The most effective deflectors for chimney do it yourself. How to choose and install a chimney deflector. Installation of ventilation deflector

№	internal chimney diameter, D, mm	height of the deflector, H, mm	diffuser width, D, mm
1	120	144	240
2	140	168	280
3	200	240	400
4	400	480	800
5	500	600	1000

If you did not find the desired value in the table, then calculate sizes in the following formulas:

D \u003d 2d;
umbrella width \u003d (1.7 ... 1.9) d;
full deflector height \u003d 1,7d.

It is necessary to determine the diameter of the chimney and the parameters of the structural elements as possible. Calculations should also be verified. It depends on how well the deflector will determine and how it will perform its functions. Pipe shapes and devices must match. For example, in the presence of a square chimney, a deflector should be done in the same way. However, such a form can lead to less efficient operation of the device.

The sequence of actions is as follows:

If going the deflector Grigorovich, It is necessary to supplement the design by the reverse cone, which in diameter should be 3-4 cm less than the protective umbrella. When both parts are made, smaller must be inserted into a large and circle by the marker. Then, on a large cone, cuts are made to the conducted line to get about 8 strips at the same distance. These elements are flexing inside. With their help, the reverse cone is securely fixed in a protective umbrella without the use of fasteners or welding.

When using the reverse cone, the umbrella mounting to the diffuser is better to carry out with spills. For this in the reverse cone, three holes are drilled in a circle. They are inserted with studs that are fixed with nuts. The cone is then attached to the umbrella, as described above. With the outer side of the top of the diffuser, loops made of tin or aluminum. The free ends of the studs are inserted into the loops and are fixed. The resulting device is not afraid of a strong wind, differs by high reliability and long service life.

Design can be chosen any. It is important to fulfill the correct drawing of the deflector, according to which the product is manufactured.

Installation

To install the aerodynamic device, three holes are drilled on the chimney. The design is inserted into the pipe and fastened by bolts. Then the axis is collected on the axis, the cylinder, the fluger and the protective cap. Everything is attached to rivets.

In order for the deflector and the device to determine the wind direction normally function, you need to monitor the state of the bearing. It should be well lubricated, otherwise his rotation will be difficult. In winter, it is impossible to allow icing design.

In any house where the furnace heating is very important to create a good thrust in chimney. A significant element in the gas removal system is a device that enhances the output rate of combustion products. This design is called a deflector, it not only increases the craving, but also protects the channel from getting garbage or precipitation. The device of this product is quite simple, which allows you to make a deflector for chimney with your own hands - the drawings for which you can make a design, understandable and simple.

There are many types of devices increasing the chimney. There are pretty uncomplicated options for popularity - the deflectors of TsAGI, Grigorovich, smoke, enshrined on brick trumpets. Although in such complex structures as deflectors-freezers, there is an advantage of which they also enjoy success - these devices provide decent cravings at any direction of the wind.

Deflector on chimney

What is needed from materials and tools

When creating any of these pipes on the pipe to remove the combustion products, you can use materials and a tool that do not require special skills such as, let's say, the ability to work with the welding machine. To make a deflector for chimney with your own hands, it is enough to use:

cyanka from the tree or rubber;
scissors for metal;
roulette;
line;
special chalk for metal;
electric drill;
riveter manual;
metal drills;
metal hacksaw;
scissors are ordinary;
simple pencil.

Types of deflectors

Make the device is easy, having available:

sheet metal, for example, galvanized iron;
metal strip or small steel corner;
aluminum rivets (drills are selected by rivet diameter);
for fastening the product on chimney bolts with nuts;
cardboard to prepare patterns.

Deflector scheme

The first stage of work - drawing up drawings and patterns

Before starting to make a deflector for chimney with your own hands, prepare drawings on ordinary paper. For each option, there is a specific ratio that affects the efficiency of the device during gases. Therefore, a product scheme is created with an indication of the size according to which the required amount of materials will be calculated and the pattern was created for the cutting of sheet metal.

After preparing the drawings, the patterns are made, used in the future for the construction of the elements of a specific device. Making the necessary patterns, proceed to the creation of a metal structure.

Grigorovich Deflector - Production Stages

The simplest product is the Grigorovich device, which is easy to make most people.

Calculations and preparation of drawings

When drawing drawings and smelling the sizes of this product, the following ratio is applied:

the height of the structure is approximately 1,7d;
the cap is needed to make 2D width;
the width of the diffuser should be about 1,3d.

Homemade deflector Grigorovich

Under the symbol D is meant the diameter of the smoke channel. If another size ratio is applied during the manufacture, it will negatively affect the efficiency of the device created.

According to drawn drawings, the patterns are prepared, used when stripping galvanized iron on the elements from which the product is then collected. To do this, on the cardboard, using a rulette, roulette and pencil, carry the contour of the elements in the deployed form and in full size. Making a deflector on the grigorovich chimney pipe, prepared patterns for an external cylinder, diffuser and cap.

Calculation of diffuser

Stages and nuances of making deflector

Using the prepared patterns, the contours of the necessary parts are applied on metal sheets, rolling out the shape of cardboard with a special chalk. In the absence of a special chalk, a simple pencil can be used. The details of the details in the places of the admission are added 20 mm, which will allow you to save the necessary configuration of finished elements when assembling.
Through the scissors for the metal, the elements needed for assembly are cut out of galvanized metal, thereby preparing an external cylinder in the unfolded form, a diffuser, both parts of the cap - the cap-umbrella together with the reverse cone.
Then, with the help of the hacksaw, the metal strips of the desired length are cut by pieces or a corner, through which all items will be connected to the finished product.
Details give the necessary form by turning and flexing them in a certain way.
The next operation is the assembly of the product. The elements are applied to each other and, using an electric drill, drill the necessary holes. Using rivets, placed in the prepared holes, the parts fasten each other.
For the installation of the Grigorovich device on the chimney, two options can be used - in the first case, through the mounting holes are drilled through which the design is fixed with the chimney fastener, and in the second version, a sciabling clamp from the strip is made by which the deflector is fixed on the pipe.

TsAGA nozzle for chimney

The procedure for making the deflector of the TsAG

The device developed at the Central Aerohydrodynamic Institute (TsAGI) is equally common. Due to the simple design, it will not be difficult to make such a deflector with their own hands.

Preparation of drawings and patterns

Initially, drawings are preparing, when compiling which produce the size of the product size. Based the diameter of the chimney, denoted by the D symbol. When designing, the product uses such a size ratio:

the size of a wide part of the diffuser is 1.25d;
ring diameter - 2D;
rings height - 1,2d;
distance from the bottom edge of the ring to a narrow part of the diffuser - D / 2;
the height of the diffuser - D / 2 + 1,2D;
umbrella width - 1,7d.

TsAGA nozzle size ratio

From how correctly the patterns are made, the ease of assembling the product from the elements created by such templates depends, and in the future it will affect the design efficiency. It must be prepared for the following details:

diffuser;
inlet nozzle;
ring;
umbrella.

Features of creating diffuser and umbrella templates

For the manufacture of the pattern of diffuser, it is necessary to make the right calculation, thanks to which the figure with the required circuit will be. To do this, use an option for creating a truncated cone. As the data on which the calculation will be built, take the following:

diameter of chimney - D1;
the diameter of the circle, by the amount of which the diffuser increases in a wide part - d2;
diffuser height - H.

Preparation of the umbrella template

With lecturer for an umbrella easier. It is necessary to draw a circle, the diameter of which will be 1,7d. Next - two radius lines so that the angle between them amounted to 30 °. Then cut out of cardboard leaflers, not forgetting to cut the area between two lines of radii.

Templates for the outer ring and the inlet nozzle have a rectangular shape, so they will not be made of difficulty.

The procedure for the manufacture of the deflector of the TsAGI

After preparing templates, work with metal begins. Making the deflector on the pipe with your own hands, do the following:

Through the lecturer paint the necessary contours of parts on the metal. At the same time added in places of the admission of 20 mm. Lines are applied by a special chalk or a simple pencil.
The metal scissors cut out the details along the contour in the deployment.
Through the knobs, the metal strips are cut into pieces of the required length or a metal corner - these segments will be used to fasten the design parts made of galvanized iron.
The carved elements are bent properly, in the places of the allen make holes, and the edges are fixed with rivets.
Next, the product is collected - elements in places overlay are drilled by each other, through the resulting holes parts are fixed relative to each other rivets.
Fastening to the chimney of construction can be prepared in two options - make holes for fasteners in the inlet or additionally from the metal band to make a scarehouse clamp for which the bolt with nut is needed.

Option of adapter for rectangular chimney

Production of the nozzle on the chimney with a square or rectangular cross section

Creating a smoking deflector with a square or rectangular cross section, you can use two design options.

Use in the adapter design

Initially prepared the drawing and template for which the adapter will be cut from galvanized steel in the deployment.

Drawing of adapter for a deflector on a chimney with a rectangular cross section

After preparation, Pekal moves to work with the metal:

Using Pekal inflicts an adapter contour to galvanized metal. You must not forget about the deposit area, adding 20 mm to the contour.
Scissors for metal cut out the product.
Then the flat element is flex in such a way that the product of the desired form is obtained.
In the place of the allen, they are done using the electric drive holes.
The hand riveter fixes the superimposed edges of the adapter.
For attachment to chimney, holes are made through which the adapter using fasteners will be fixed on the pipe.
In the location of the device and the adapter also make holes for tie bolts.

Smoke

Technology Creating a simple smoke

The second option is the manufacturer of a visor fixed on a rectangular chimney. With the task, how to make a doom on the pipe with your own hands, any person will be able to figure out, since the design is extremely simple and the calculations are simple.

The drawing is prepared on the basis of calculations, thanks to which they find out the necessary dimensions of the product. Then, on the basis of the drawing, the pattern was created, used when drawing contours of parts on a galvanized iron sheet.

Drawing of the smokery on rectangular chimney

After preparing the template, the production of the product itself is proceeded:

Using the pattern, the contours of the unfolded smoke of the smoke on a galvanized iron sheet applied a special chalk. You must not forget about the places of the allen, adding 20 mm on the edges of the part.
The metal scissors are cut out the details according to the contour.
The metal strip is cut with a metal strip or corner. To fix the deflector on the chimney, most conveniently use the corner.
The parts cut from the sheet are bended so that the smoke umbrella accepted the necessary form.
Next, build products with drumming in the right places of holes and fixation of parts rivets.

Making a deflector-free

Independent manufacture of deflector-free

The fluger allows you to reduce the height of the pipe by increasing the thrust, as it is always in the right attitude towards the wind, prevents falling into the pipe and adorns the roof.

Tools and consumables for work

To make one of the variants of the Fluagark on the chimney pipe with your own hands, you need to add to the above tools and materials Add:

set of wrenches;
cut pipe;
metal (preferably from stainless steel) rod or ready-made stud;
cut for cutting threads on the rod;
tap for cutting threads under fixing bolts;
bolts for fixing bearings in the pipe;
8 nuts that need to be screwed into the rod for fixing bearings and fastening the deflector housing.
two bearing, the size of which is selected by the diameter of the rod and the inner diameter of the pipe.

Drawing of the deflector in the form of a fluger

Step-by-step instructions and important comments

Operating procedure:

Initially make the drawing along which it is further made of patterns for details from galvanized steel sheet.
Using the pattern, the contours of the elements of the deflector on the steel sheet with a special chalk or marker.
Metal scissors cut out parts made of metal sheet.
Of the prepared elements, the body of the deflector is collected by drilling holes and fasten them with rivets. You must not forget to make the brackets by which the case will be attached to the rod.
Cut the rod either the heel of the required length is enough to fasten the bearings and fixing the deflector housing.
If the rod is used, then the thread is cut.
Further on the stud fasten two bearing with the distance between them, which is necessary to create sufficient stop when the deflector-free deflector is rotated. To fasten each bearing, first get the first nut, followed by the bearing on the axis, then the second nut turn the second nut and perform the tightening of the nuts to a good fixation of the bearing.
Crop the pipe to the required length.
The pipes are done in the places of bearing places. Cut by a tumbled thread for bolts that bear the bearings will be fixed in the pipe. Also prepare holes for fixing the supports that lock all the device.
The steel strip is made by a ring for fixing the deflector to chimney.
Cut the segments used as a support for fastening the block with bearings to the ring fixing the product on the chimney.
Perform the final assembly of the product using rivets and fixing bolts.

Decorative weatherman

Options for how to make a deflector on the pipe with your own hands, quite a few. Each chooses what type of device is best suited. It is only necessary to note that such a design, placed on a pipe for the removal of combustion products, performs several useful functions - increases the thrust when the gases are tapped, protects the chimney from entering the garbage and precipitation. After installing the deflector on the chimney, the efficiency of heating in the house is significantly increasing.

Good traction is the most important condition for the normal operation of any furnace. Most often, the problems with the burden are caused by wind, atmospheric precipitation and garbage, scoring chimney. The most convenient and simple solution in such situations is the installation of a deflector. This device does not give the wind to whiten the pipe, protects the chimney from the fallout and leaves, contributes to the free removal of combustion products. To correctly perform the installation of the deflector, you should read more details with the features of its design.

Standard device includes three main elements - cylinder, diffuser, protective cap (umbrella). Additionally, the design is equipped with ring abnormalities, which are located at the bottom and around the diffuser. There are several varieties of deflectors that differ in the form, dimensions and number of elements, but all of them, regardless of the species, work according to one principle.

The design is installed at the very top of the chimney and creates an obstacle to air flow. When the wind strikes the wall of the cylinder, it loses its strength and is broken into a plurality of small air flows of weak intensity. Some of them rises through the case and captures the smoke coming out of the pipe. This is exactly what increases the thrust in the chimney channel.

Due to the absence of curvatures, smoke and carbon monoxide, do not fall back into the pipe, and completely output. In addition, the deflector prevents the pipe clogging through the top and performs decorative functions.

It has been proven that after installing the deflector, the efficiency of the heating device increases by 15-20%. Of course, the deflector itself will not give anything if the chimney is not installed enough or incorrectly selected the cross section of the coupling pipe. It matters and the location of the pipe on the roof.

Types of deflectors

Type of device	Characteristics
	The most common option. It has a cylindrical shape, is made of stainless steel or galvanized steel. Connection type - nipple, flange
	The design is similar to the deflector of the TsAGI, but has small differences in the upper part. It is made of galvanized, stainless steel and copper, most often used for chimneys in the baths
	Advanced version of the TsAGI is designed for areas with predominant low wind. Provides good traction even in windless weather
	Very efficient and simple design of open type. Provides high-quality cravings regardless of the direction of the wind. Made from galvanizing and stainless steel
	Reliable design, effective for any direction of wind. It is made of stainless steel, the connection is performed using a knob on the device pipe
	A device with a rotating housing and fixed in the top of the vane. It is made of stainless steel or painted carbon steel
	The device rotates only in one direction, effectively protects the chimney from clogging and precipitation, is excellent for gas boilers. Does not work in the calm and under icing

The main differences are in the form of construction and the number of components. Material for the manufacture of such devices is stainless and galvanized steel, less often copper. In form, they are cylindrical, square, round, open and closed type. The devices of one species may differ in the upper part: some products are performed with a cone-shaped umbrella, others have a double or hip roof, the third is made flat or with decorative figured elements.

The diameter of the deflector varies in the range of 100-500 mm, the width of the diffuser from 240 to 1000 mm, the height of the structure - from 14 to 60 cm.

The device is attached to the chimney with the help of brackets, clamps, bolts, using the sealing tape. For manufacture, it is used with a thickness of 0.5 to 1 mm thick, depending on the diameter of the deflector itself. Additionally, the device can be equipped with a brawler if there is a risk of roof fire.

FEATURES OF MONTAGE

The location of the deflector directly affects its efficiency. When installing the design to the chimney, certain conditions should be observed:

Self-making device

To work, you will need:

a leaf of galvanized or stainless steel with a thickness of 0.5-1 mm;
scissors for metal;
riveter;
drill;
tight paper or cardboard sheet.

The most important stage is drawing up the drawing. To do this, it is necessary to measure the inner diameter of the chimney and calculate the parameters of the product on the table.

If the internal diameter of your chimney differs from the above parameters in the table, the calculations are performed as follows:

the diffuser width is 1.2 D;
the width of the protective umbrella is 1.7-1.9 d;
the total height of the structure is 1.7 d.

And measurements, and calculations should be as accurate as possible so that it does not have difficulty in installing the design and its subsequent operation. If the pipe has a square cross section, then the deflector must be made square, although the cornering of the case slightly reduces the efficiency of the device.

Step, Nos.	Description	Illustration
Step 1.	The paper performs the drawing of the details of the deflector in full size and cut.
Step 2.	Billets fasten and try on each other. If all the elements coincide, you can start the disclosure of the galvanized.
Step 3.	Templates are unfolded on galvanized, carefully rub the marker, cut out with scissors for metal. On cuts, the metal is sweeping on 5 mM passatages and fell into the hammer.
Step 4.	In the places of bends, the metal must be opened with a hammer to make the edges of thinner.
Step 5.	The discharge of the diffuser is cooled with a cylinder, drill holes for fasteners and connected by bolts or rivets. You can use and welding, but not only arc, and semiautomatics so as not to burn metal through.
Step 6.	The external cylinder makes the same way. Next, the cap is minimized by the cone and also combine rivets or welding.
Step 7.	From the galvanized, 3-4 strips of 6 cm wide and up to 20 cm long. The strips are sweeping from two sides along, closed with a hammer over the entire length. From the inside of the cap, retreating from the edge of approximately 5 cm, drilled around the circle the desired number of bolts under the bolts. Fix the strips of galvanizing on the cap and give them a P-shaped form.
Step 8.	With the help of these homemade brackets, the cap is attached to the diffuser, and then insert the entire design into the shell.

If in the design there must be a reverse cone (the grigorovich deflector), the diameter of the protective umbrella is made by 3-4 cm more than the diameter of the cone. After assembling both elements, the cone is applied from the inside of the umbrella and drive around the perimeter with a marker. Then they make two cuts on the protruding part of the umbrella and sweep the resulting strip inside. In the same way, another 6-8 strips are made at an equal distance from each other, bend them inside and reliably fix the reverse cone without additional fasteners and welding.

To the diffuser, the cap with a reverse cone is more convenient to fix with construction studs. To do this, three holes around the circle are drilled before installing the cone on the umbrella, the ends of the studs are inserted and the nuts are twisted. Then we put on top of the umbrella, the cone is fixed in the method described above. In the upper part of the diffuser, from the outside, stick the hinges from tin or aluminum and insert the lower ends of the studs. Such a design withstands the strong gusts of the wind, serves a long time and reliably.

Such a way can be collected by a deflector of any type, the main thing is to make the right drawing. The only difference will be in the amount and form of details. The finished device remains only to mount the chimney.

Installation of deflector

You can set the design in two ways - directly to the chimney and on the cut pipe, which is then put on the smoke channel. The second method is much more convenient and safer, since the most time-consuming process is performed below, and not on the roof. Most factory models have a lower nozzle, which is simply worn onto the pipe and fastened with a metal clamp.

Fastened Deflector - Photo

To install a homemade deflector, you will need a tube cut, a diameter of a little larger than the diameter of the chimney, and threaded studs.

Step 1. At one end of the pipe, retreating from the cut 10-15 cm, mark the circumference of the drilling site under fasteners. The same labels also put on a wide part of the diffuser.

Step 2. Drill holes in the diffuser and the pipe, try the elements to each other. The upper and lower holes must accurately coincide, otherwise the fasteners will not be able to install exactly.

Step 3. Drops through the holes of the studs and fix them with nuts on both sides on the diffuser and on the pipe. Screw nuts should be uniformly so that the deflector body is not deformed.

Step 4. Raise the design to the roof, put on the chimney pipe and fasten the clamps.

It is very important that on this site there is no gaps between the elements, and therefore it is necessary to delay the clamp very tightly. Additionally, you can process the joint along the perimeter with heat-resistant sealant.

Installation of such a deflector is a bit different, as its design has certain differences. First, three holes are drilled in the smoke tube at one level under the mounting bolts. A ring part of the device is inserted into the chimney slice and fixed with bolts. Next, the axis is inserted into the ring bearing, the cylinder is dressed on it, then the fluger canvas, protective cap. All items are connected using brackets or rivets.

When choosing a deflector with a vane, remember that bearings require regular lubrication, otherwise the device will not rotate. It is also impossible to allow icing icing, and knock down, as soon as it appears.

How important the ventilation system in the house is likely to understand the beginners of developers and those who decided to conduct the modernization of this system. Properly working ventilation is the key to good well-being of the inhabitants of the house, the lack of unpleasant odors (dampness, mold, gary and others) and condensate on the windows, the timely removal of the accumulated carbon dioxide and radon (harmful gas entering the construction structures from the soil).

What is a deflector and why he need

It is known that the most common ventilation system is natural. It has a flow of fresh air and the exhaust exhaust occur with the help of different temperature and atmospheric values \u200b\u200bindoors and beyond. But, unfortunately, for the ventsy system, this difference of regimes is relevant only during the cold season. In the summer months, the pull in the hood is practically absent. But during this period it can be "forced" to work. The effectiveness of the ventilation system is favorably affected by such a phenomenon of nature like wind.

And in order to enhance such an impact, in the exhaust part of the ventilation system, a special device - Volpert-Grigorovich deflector. Installed - on the top of the exhaust pipe or channel. The basis of the work is the physical laws, namely, Bernoulli law.

Important! Wind streams, lying walls of the deflector outside, create discharged air almost all over the perimeter of the device. Such a process makes it possible with a sufficiently large force to "suck" the spent air from the exhaust. If it is simpler, then the additional thrust is created by the wind, blowing a deflector, and it occurs even from a small breeze.

Design of the deflector Volpert-Grigorovich

Interest in the deflector of this design is indicated by the fact that it was connected by the development of Volpert and Grigorovich. It consists of only three elements bonded:

diffuser;
covers;
reverse cone.

The presence of a reverse cone (under a protective visor) makes the efficient operation of the device at low winds. A feature of the Volpert-Grigorovich deflector is the curvilinear surface of the diffuser and the presence of a lid in the form of an umbrella. The reverse cone allows not to make such a rather complex surface of the diffuser, the more simplifies the design. Therefore, the homemade deflector of Volpert-Grigorovich is easy to manufacture and, at the same time, more efficiently, other devices for improving work or ventilation (chimney) system.

The deflector is made by rounded shape. Perhaps a square device if the installation is performed on a square air duct. But, as practice shows, the design of such a form is not desirable, since the angles do not give the opportunity to correctly move around with air masses, and this affects the quality of the work of the deflector. In such cases, they come out of the situation with the help of an adapter installed on a vent car.

Device effectively all year round

Installing the device allows you to create cravings at any time of the year. This is the main advantage of the Wolpert-Grigorovich deflector. In addition to it, there are some more indisputable advantages.

Due to the simplicity of the design, it may be made independently.
Returning to the school course of physics, it should be reminded than the longer the pipe on the roof, the better the thrust. The deflector, not extending the chimney, will increase the craving at as much as the 2 meters of the pipe added.
The efficiency of the heating device increases to 25%, and the ventilation system is up to 20%.
Installing the design deflector Volpert-Grigorovich allows not to use a forced exhaust system.

Warning! The deflector cannot be put on the exhaust pipe of the gas boiler. This requirement is reflected in SNIVA 41-01-2003 Heating, ventilation and air conditioning and is mandatory for systems installed in all buildings and structures (residential and non-residential premises).

Making a deflector with her own hands: Step-by-step instructions

The design is enough to make it, but it is necessary to make calculations. It is very important to determine all the sizes, otherwise their violation is fraught with improper work of the deflector, which loses all the meaning of its use.

Step number 1 Calculation

For settlements, it is necessary to know the main indicator - the cross section of the pipe to which the deflector is installed. Knowing it can be calculated the remaining sizes.

A good thrust is the key to the normal operation of the furnace, therefore the design of the chimney should be given no less attention than the most heaters. To improve the aerodynamic properties of the chimney, a special reflector is installed on its edge, or, in a different way, the deflector. This simple fixture will not only increase the thrust, but also protects the chimney from garbage and precipitation. There are various designs of reflectors ranging from devices developed by homemade craftsmen, and ending with models over which engineers have worked out. Any of these deflectors can be made with their own hands, if you follow the drawings and have the minimum skills of working with the metal.

Why do you need a deflector for chimney and how it works

Even the best oven will not be able to show the good results of the work if its chimney will not create the necessary traction. It is this factor that affects the efficiency of air supply and timely removal of exhaust gases.

Various deflectors have common structural elements.

For the manufacture of deflectors, it is best suited for a sheet galvanized or stainless steel. In addition to these materials, the industry mastered the release of devices with a protective enamel layer or a coating of heat-resistant plastic.

Among the many deflectors that can be made with their own hands, you can highlight several of the most popular designs.

The TsAGA deflector refers to universal devices that can be installed on any pipe - oven, exhaust or ventilation. Developed in the Central Aerohydrodynamic Institute. Zhukovsky device has a simple design with an open running part and protect against reverse thrust. There are two varieties of TsAG reflectors intended for external or internal installation. Thanks to multiple advantages, the deflector of this type was widely popular with domestic masters. At the same time, the design is not devoid of flaws. "Weak link" is a narrow passage section, which can overlap with a layer of nondes on the inner cylinder. In addition, the TsAGA deflector is not effective enough at low wind and calm - under these conditions, its design creates a small resistance of natural straight.

Dellek TsAGI is characterized by simple design and excellent performance.

Tarldy

This deflector received its name because of several cones (plates) in its composition and refers to devices with an open running part. The reflector has a protective umbrella combined with a cone and the lower part in the form of a cap with a hole for the exit of smoke. The vacuum occurs due to the plates directed towards each other, which form a tapering channel for incoming air flows.

In the disflector, the vacuum occurs in the gap between the cones directed to each other

The device has a design with a reflector design. Differences relate only to the top of the deflector. The cap protecting the inner part of the chimney from garbage and precipitation is installed on top of the diffuser, which eliminates some shortcomings of the device developed in TsAGI. Zhukovsky.

"Volper" has minimal differences from the TsAGA thrust amplifier, which provide him with advantages in the absence of wind

One of the most repetitive structures is an advanced deflector of the TsAGI. Smoke that comes from the chimney, passes through the narrowing channel of the diffuser, which increases the speed of its expiration. The Grigorovich deflector is best suited for chimneys installed in lowlands and in areas with a weak movement of air flows, since it is able to give good traction even in a full calm.

Grigorovich's deflector - an ideal solution for terrain with weak air currents

N-shaped

Deflectors, the silhouette of which resembles the letter "H", are designed to equip the chimneys of powerful furnaces and boiler plants. In such devices, the flow of exhaust gases is divided into two parts and with acceleration goes through two side diffusers. The advantages of the structure are to significantly improve the thrust when the air masses move in any direction. In addition, the n-shaped deflector does not require a visor setting, since the mouth of the chimney protects the transverse tube of the device.

H-shaped thrust amplifiers are designed for installation on chimneys of powerful thermal units

Rotating

The device is performed as a sphere with a plurality of curved side blades. The presence of blades allows the instrument to rotate in a certain side and work like a turbine. Rotary deflectors are best suited for gas boilers and perfectly cope with the protection of chimney from garbage and precipitation. The disadvantages of this type of devices consist in their low efficiency in icing and the absence of wind.

Numerous blades of the rotating deflector create a traction like a turbine

Deflector-weatherman

Such a reflector has a rotating part (flugark), which rotates when the wind direction changes. At the same time, the deflector curtain flashes the chimney from the incoming air masses and contributes to the appearance of the vacuum from the leeward side. Due to this, an active combustion products are carried out, which eliminates the inverse thrust and the formation of sparks.

The deflector with a flugyant can rotate, orienting the reflector exactly across the direction of the wind

How to make a deflector do it yourself

Regardless of which model of the deflector is selected for manufacture with your own hands, work is carried out in a certain sequence. First, the furnace pipe is made and on the basis of the tables and drawings perform the calculation of the parameters of the selected design. Further make up the deflector housing and drawings of parts with real sizes. After that, from the cardboard was cut out the patterns of all components of the deflector and transfer them to the metal. All that remains is to cut the workpieces of parts and assemble them into a single design.

As an example, we will show how you can build one of the most popular designs in our country - the deflector of the TsAGA. This reflector on the chimney can be made with their own hands even with minimal plumbing skills.

What will be needed for the manufacture of the TsAGA deflector

Before starting work, such materials and tools should be prepared:

sheet galvanized or stainless steel thick up to 1 mm;
tight cardboard for making patterns;
pencil;
line;
compass;
tOOL-TOOLS;
pliers;
scissors - stationery and metal;
drill and swell to work with steel;
skin.

For the construction of rotating deflectors, additionally need bearings, metal pipes and rods, bolts, nuts and a tool for cutting threads.

Design work

Before starting the metal cutting, you need to calculate the design parameters and make drawings. To determine the dimensions of the deflector, it is required to measure the inner diameter of the chimney pipe (D) and make the calculation according to the following ratios:

the width of the outer ring is 2D;
the height of the outer part with the cap is 1,2d + d / 2;
diffuser diameter at the top - 1.25d;
the diameter of the visor (umbrella) varies in the range from 1,7d to 1.9d;
the height of the fastening of the outer ring - D / 2.

The drawing of the deflector of the TsAGA is applied proportions of the parties necessary to determine the sizes of individual elements.

For convenience of calculations, the external parameters of deflectors are made to the table, where they are presented for the chimney of the most common sizes.

Table: Constructive sizes of drug deflectors for chimneys of various diameters

Chimney diameter, mm	Diameter external rings, mm.	Height external rings with a cap, mm	Diameter diffuser from side release, mm.	Diameter cap, mm.	Height fastening external rings, mm.
100	200	120	125	170–190	50
125	250	150	157	212–238	63
160	320	192	200	272–304	80
200	400	240	250	340–380	100
250	500	300	313	425–475	125
315	630	378	394	536–599	158

Measurements and calculations should be performed very scrupulously, because the aerodynamic quality of the design and the possibility of its chimney without cracks and gaps depends on them. When designing a deflector, not only the diameter of the chimney, but also the shape of its section is taken into account. For a square chimney, you will need a deflector of the same configuration, at least the presence of angles and affects the efficiency of the thrust amplifier.

Making templates

The molel diffuser of the TsAGA deflector is an extension of a truncated cone.

Pattern for the manufacture of Diffuser TsAGA is a truncated cone

To make the pattern of the part, it will take the calculation using such data:

chimney diameter - D1;
the diameter of the diffuser from the release side - D2;
the limit height of the diffuser - H.

Glazo umbrella make it even easier. To do this, the circle with a diameter of 1,7d is drawn on the cardboard. You should then select the sector with an angle of 30 degrees at its base and leave a 15-20 mm science for fixing the cone board.

To fix the side of the cone, you need to leave

It remains to cut molds along the contour and separate the triangular area (selected sector) from it).

The outer ring and the inlet nozzle are performed in the form of a cylinder, so the manufacture of their patterns does not cause difficulties. It will only be necessary to cut rectangles with the parties equal to the height and the length of the circumference of the corresponding parts.

Installation instructions

After all the details of the TsAGA deflector were cut out, they produce a full-scale layout and check its compliance with the estimated dimensions. In the future, this will avoid situations where individual parts of the device are not suitable for each other, and the connecting dimensions of the structure do not correspond to the chimney diameter.

Full-scale modeling of cardboard deflectors avoids errors in work

After checking, the layout is disassembled into the components of the elements and proceed to the manufacture of metal blanks. This work is performed in stages.

We carry out the contours of lectured on the metal sheet, for which the treadmill is used from solid alloys, chalk or simple pencil. In the locations of the joints are added 20 mm in order to leave a small science.
With the help of metal scissors, the sheet of galvanized or stainless steel is cut.
The cuts of the external contours of the parts are sweeping no more than 5 mm, they are peeling with the help of pliers and get into the hammer.
The billets of the outer ring and the inlet pipe are folded with a ring with a 20-mm visiting one part to the other and through the axial line of the formation is done through holes. The drilling step depends on the size of the elements and varies from 20 to 60 mm.
After turning the diffuser in the ring, its edges are fixed with ripples
Details are connected using ripples or bolts.
When assembling a deflector, a semi-automatic type welding machine can be used - it will not give the workpiece and will allow welding in the protective gas environment.
The cap, diffuser and protective visor make the same way. Along the flexural lines, the metal is closed with a hammer. It will make a leaf thinner and will make it much less effort when processing it.
Puppet, which will consolidate the cone of the deflector, must be taken into account at the modeling stage
3-4 brackets are manufactured by which the individual details of the deflector will be connected to each other. For this, the strips of 30 mm wide and up to 20 mm are cut out of the metal sheet. To increase the rigidity of the holders by their outer edge, they make flaming width of 5 mm, which is tested with a hammer.
From the inner part of the cone make an indent 50 mm and the holes for fastening brackets are performed.
After fixing brackets to the cone, you need to adjust them to the side opposite to the top
Metal stripes are attached to the umbrella and sweep at an angle of 90 degrees.
Cone with brackets and a protective cap attach to the diffuser.
For final deflector assembly use ripple connections
The design is inserted into the outer ring and fasten with the help of ripping connections. This assembly of the TsAGA deflector can be considered completed.
If the instruction is accurately followed by a functional deflector

In the same way, you can make a deflector of any type. The exceptions are perhaps the rotating structures, which, in addition to tin work, require the manufacture of a rotary assembly.

Features of the manufacture of rotating reflectors

Since the manufacture of rotating deflectors has a number of features, consider in detail how to build a thrust amplifier with a rotating flugyant.

For the manufacture of a deflector with a rotating flugyant will need project documentation

In addition to the tools and materials that will be needed for the manufacture of the design from the TsAGA, add:

long hairpin with M10-M12 thread;
segment of steel pipe Ø 30-50 mm;
2 bearing with an outer and inner diameter that corresponds to the selected pipe and stud;
m8 bolts for fastening rotational nodes;
m10-M12 nuts in the amount of 8 pieces;
set of taps;
wheel keys.

If the suitable stud for making the axis of the thrust amplifier was not found, do not despair. It is not difficult to make it from the steel bar of a suitable diameter, using a rash for cutting the metric thread M10 or M12.

The deflector with the flugyant can be addressed to the view of the colonic bird - it all depends on the fantasy and the skills of the Master

The initial stages of work do not differ from the manufacture of static deflectors. At first they make drawing, cut out the pattern and transfer their contours to the sheet steel. The billets are cut with scissors for metal or electric bison. The flaggle curtain is assembled with ripples. The only difference lies in the fact that the body will need to attach the brackets by which the reflector will be recorded on the axis.

The stud is shortened so that its lengths it is enough to fix the bearings and the reflector housing.
Bearings are installed on the axis. The distance between them should ensure the stability and monolith of the rotary node. The attachment of rolling knots is performed using a pair of nuts, tightened with sufficient effort.
Sliced \u200b\u200bthe desired piece of steel pipe. In places where bearings will be placed, perform drilling and cut the M8 thread.
In the pipe drill holes to which the holding brackets will be attached.
From the segment of the steel strip with a thickness of 1.5-2 mm and a width of 150-200 mm bend ring (coupling) corresponding to the outer diameter of the chimney.
Four brackets are cut from the same strip, which the ring will be attached to the pipe of the rotary device.
The reflector is attached to the axis using two pairs of nuts, which are fixed in the upper and lower part.
The axis with bearings is inserted into the pipe and fixed with M8 bolts.
A fastener ring is installed on the deflector. For this, the manufactured brackets are alternately fixed on the pipe of the rotary assembly and the connecting coupling. On this assembly work end.

In the process of work, it is necessary to monitor the state of lubricant in the bearings, otherwise the design will rotate with difficulty or comes at all.

Installing a deflector for chimney

When installing a deflector, a number of conditions affect the effectiveness of its operation must be performed:

in areas with gusty winds, it is rational to use H-shaped thrust amplifiers;
in the northern regions it is unwanted to establish the deflectors of the rotating type;
when installing a round deflector on a square chimney, a special adapter is manufactured;
the thrust amplifier is not recommended to be mounted where the neighboring buildings can create an aerodynamic shadow;
the device for amplifying thrust should be blown away by the wind from any direction.

To install the deflector, you can use in two ways. In the first case, the device for amplifying thrust is fixed directly to the chimney, using clamps, rivets or threaded connections. The second method implies the attachment of the deflector to a special adapter, the internal diameter of which allows you to simply put the device for chimney. The last way is convenient to apply if access to the chimney is limited or it has a significant length.

For fixing a deflector on a chimney, a metallic clamp of a suitable diameter will fit

In general, the installation of the deflector looks like this:

Pick the pipe segment, the diameter of which several millimeters exceeds the size of the chimney.
At a distance of 10-15 cm from the end of the workpiece, the holes under fasteners are done. Such drills are performed in the connecting connector of the reflector.
The holes in the pipe and the deflector are combined, the studs are shifted through them and fix the nuts on both sides. In the future, the studs protruding inside the pipe will serve as a focus for the chimney pipe.
The device is raised to the top and sit on the chimney. For the final fastening of the design, a metallic clamp of a suitable size is used.

In order to eliminate the danger of air supply, the joint place is sealing a basalt car, asbestos cord or any heat-resistant sealant.

From how correctly the thrust in the chimney will be organized, not only the efficiency and productivity of the thermal unit, but also the safety of your loved ones depends. Improve the removal of exhaust gases will be able to even a simple deflector made with their own hands. It is only necessary to follow the exact dimensions and in the manufacture of a device for improving the thrust to show maximum accuracy and increased attention.
