Deflector for square chimney. Flugart on the chimney pipe: what is needed and how it works. Working deflector with windproof system

Chimney is designed to remove harmful combustion products from the room. The smoke channel provides a natural thrust resulting from a pressure and temperature difference. To maximize the possibility of chimney, a smoke pipe deflector is installed on its upper part.

Principle of operation of the device

The deflector, by virtue of its design, contributes to the strengthening of natural thrust in chimney. This process is a consequence of low pressure zone when air exposed to the components of the device.

In addition to strengthening the thrust of the chimney, contributes to the protection of the chimney from clogging and moisture.

The deflector mounted on the chimney pipe is capable of increasing the system of the system by approximately 20%.

Choosing a deflector

Before installing the headband of the chimney, it is necessary:

1. deal with the existing species and features of each design;
2. choose equipment, depending on the diameter of the chimney used.

Types of device

Currently, smoke pipe deflectors are divided into the following types:

1. deflector TsAGI. The most common device. The equipment works better with strong wind. The higher the deflector is installed above the roof level, the more the thrust occurs in;

1. the deflector Grigorovich. The device works poorly at the bottom wind;

1. singite rotating deflector. The device works on the basis of the fan principle;

1. H-shaped deflector. Widespread. Successfully operates at any direction of the wind;

1. deflector "Astato". Refers to the category of open headings;

1. round Deflector "Volper";

1. deflector Wheel. Unlike ordinary deflectors, the device rotates depending on the wind.

Such a device consists of the following items:

1. half-cylinder protecting the system from strangling wind;
2. covers preventing clogging of the chimney;
3. the canvas rotating depending on the direction of the wind;
4. central axis connected to all device elements;
5. sanger serving an additional element of the attachment of the deflector to the smoke pipe.

Selection of deflector

The selection of the device is determined by the diameter of the smoke tube used and is calculated by the table below.

The parameters n and D devices correspond to the following scheme.

If the required deflector parameters cannot be selected according to the table presented above, they are calculated based on the following rules:

1. the height of the device (denoted as H) should be at least 1.6 internal diameters (denoted as D);
2. the width of the diffuser located in the upper part of the equipment (D) is 1.3 internal diameters (D);
3. the top cap or umbrella depending on the selected model of the deflector should be at least 1.8 from the inner diameter (D).

Installation of the head

Installation of classic deflector

Installation of the deflector is not complicated. Install the device can be independently without resorting to the help of qualified specialists.

For installation, you will need:

1. equipment itself, selected at will and appropriate parameters;
2. tools for fastening bolts to which include: screwdriver or ordinary screwdriver, pliers, wrench and so on;
3. two stairs. One for lifting on the roof. Another for lifting on the lip of the roof.

When installing the head, you can not forget about the technique of own safety. For high-rise work, it is more expedient to use additional insurance, which prevents the possible advent of the installer.

Before starting the installation of the deflector, it is recommended to disassemble the acquired device and carefully get acquainted with the form of the structure and existing internal connections. Mounting itself is made according to the following scheme:

1. the bottom glass of the device is attached to the yield of the chimney with bolts;
2. using special clamps to the bottom, the upper part of the deflector or diffuser is attached;
3. the cap or umbrella protruding the cover of the equipment is installed on the brackets.

Installation of deflector-weather

The method of installing a deflector-free-free or windproof deflector is somewhat different from the installation of other types of devices.

To establish such a deflector (based on the drawing), you need to hold the following steps:

1. inside the installed chimney (in the figure, the letter A) are securely pinned bearings or letters (designated e and g);
2. the central axis - b is attached to bearings;
3. in the specified sequence, the axis is dressed: a semi-cylinder, which is a screen (D), a deflector cover (g), a fluouger web (B).

Any type of deflector is subjected to a constant influence of strong winds and precipitation, so when installing the structure, special attention is paid to the strength of all fasteners.

To properly establish a deflector in various situations, it is necessary to clearly follow the following advice:

1. under the device cover, it is advisable to additionally install the check valve that protects the correct system's proper performance even at the grassroots wind. Some deflectors are already equipped with a device. For other, the check valve is acquired and mounted additionally;

1. for the installation of a round deflector on a smoke tube of a square or rectangular shape, special adapters are used. Additional adapters are used and, if necessary, arranging the transition from one diameter to another;

1. all components of the device must be securely secured. If the deflector is installed on pipes having a large diameter, the equipment requires additional attachments, usually constructed from metal strips. It is necessary that the device is as little to be exposed to a strong wind capable of damaging the system.

Deflectors are used exclusively for furnaces and fireplaces that work on fuel solid. Equipment relatively inexpensive. Make a deflector, as well as install it, you can independently.

Regardless of the type of fuel, the mandatory part of the heating system is chimney. It depends on its competent device, it will be so warm in the house.

A special type of fuel gas, because it is insecable, so many are concerned about the question: is it needed a deflector on the chimney of the gas boiler and will there be such a solution to the problem? Let's try to deal with this difficult question in our material.

In modern performance there are deflectors of different types, so you can choose a model for the house performed in any architectural style.

Structurally, these devices differ:

• flat top;
• two skates;
• semicircular lid;
• folded impurge.

Each of them is distinguished by certain advantages: the opening cover on the deflector allows control over the process of removal of combustion products.

As a decorative element for the roof made in the style of Modern, the flat top is perfect, the best protection against atmospheric influences is a double mini-roof. A galvanized metal is mainly used as a material for their manufacture, but sometimes it is covered with a layer of plastic or enamel.

What is a deflector?

Strong wind is able to disrupt the stable operation of the gas boiler. In such conditions, automation and boiler are often triggered. Combustion products from the gas boiler with ineffective disgust provide a threat not only to health, but also the lives of people.

To enhance cravings by optimizing airflows or deflectors are used. Translated, its name sounds like a reflector deflecting. The Bernoulli effect was used in its work, based on lowering pressure during the flow around the obstacle by air flow. It deflects air masses, increasing the strength of the chimney's main flow.

The chimney of a gas boiler, equipped with a deflector, will not fade with strong wind gusts. The design becomes more efficient, because The force of traction increases to 20%

The thrust amplifier operates effectively with any wind power and even during strong gusts, if available, the thrust will not turn into. But with complete ulothels, this aerodynamic device performs the role of an umbrella and practically inactive, and sometimes reduces the thrust. For this reason, many specialists do not advise conflectors to gas chimneys.

Despite the increased requirements for the deflector installed on, in some cases this is the only solution to the problem. If this device is not laid in the project, it is necessary to coordinate its installation with gas workers. Only by performing this condition, you can start the installation of the deflector.

According to the specifics of the device and associated with this principle, the deflectors are divided into the following varieties:

Self assembly of device

First, it is harvested pattern, then lay them on a sheet of metal and cut parts using special scissors. The housing is folded, fasten the edges with rivets. The onward and lower cones are fixed on with each other, using the first edge for this. It is more and in it can be cut in several places special fasteners with a width of about 1.5 cm, and then bend them.

Before assembly in the lower cone, 3 racks are installed, evenly distributing them around the perimeter and using threaded studs for this. To connect an umbrella with a diffuser on the latter, fasten with rivets loops made of metal stripes. Racks are screwed into the loop and for greater reliability perform fixation with nuts.

Next, work on the installation of the manufactured deflector for the chimney of the gas or other type of boiler. The collected device is placed on the pipe and fix with the use of clamps, not allowing gaps. Sometimes the joke is treated with heat-resistant sealant.

Assembling a simple plate model

The easiest to implement the project is the manufacture of a disflector plate model. Such a hood for chimney can easily be made with your own hands. Its geometric parameters depend on the diameter of the pipe:

For heat plants that work on different types of organic fuel - an indispensable condition of smooth and efficient work is to install high-quality smoke systems. To combine the fuel in your stove or boiler with full heat transfer - it is necessary to organize the air flow to the flue space, and the combustion products and smoke should be removed not only from the furnace, but also beyond the building. In the event that the heating device does not provide for the installation of the air superior system, then the traction in the furnace is created by an exceptionally chimney system. Flugart on the chimney pipe is the completion of the smoke system and contributes to ensuring uninterrupted and efficient operation of the furnace.

Fluagarks and deflectors are installed on pipe shells and are designed to deviate flue stream in accordance with the direction of the dominant wind. Actually the name "Deflector" itself is a tracing with a Latin concept "reject".

Deflectors and flugars are designed to ensure complete gas removal from the chimney system. Stagnation and incomplete removal of combustion products occur in chimneys for the following reasons:

• A strong impetuous wind can interfere with the normal outlet of the combustion products from the chimney. The wind, strangling in an unprotected tube glider, can break the chimney thrust.
• Also, incomplete removal of combustion products can interfere with the wrong arrangement of the chimney on the roof.
• Combustion products can be stirred in a pipe and due to its improper design: insufficient cross-section and excessive amounts of knees with bending.

Fluagarks and deflectors on the headings of chimneys act on aerodynamic principles, forming a stable thrust in the pipe, regardless of the current direction of the wind stream. These devices change the air vents vector, directing it to the side, which ensures the most effective removal of combustion products.

When using fluguards and deflectors, the wind does not interrupt the flow of expiring combustion products, and enhances it. These devices also compensate for the reduction of thrust caused by turns in the chimney system.

The correctly selected deflector or fluorca provides an increase in chimney efficiency up to 20 percent. Also, this equipment protects the chimney channel from atmospheric precipitation from entering it.

Deflectors and flugartes can be installed on both individual and collective chimney systems. These devices can also be placed on ventilation pipes, including on the ventilation systems of garbage disposal.

Construction of deflectors and flugames on flue pipes

The main parts of deflectors and flugas installed on the flue pipe are the following details:

• The lower part is a cylinder, which can be made from metal, ceramics or asbestos.
• Next to the cylinder attaches the top glass. It is fixed on several racks and has a shape of a truncated cone expanding down.
• To protect against atmospheric precipitation to the top glass-diffuser, an umbrella-cap having a cone-shaped form is mounted.

The upper and lower parts of the diffuser can be equipped with ring abnormalities. They deflect the wind flow from the vertical direction. The design of deflectors and flugars is calculated in such a way that the wind stream from any side does not interfere with the effective expiration of combustion products from the chimney channel, and formed a stable thrust in the pipe.

Materials of making deflectors and flugas usually serves galvanized steel. Such material is almost perfect for working in aggressive conditions of the external environment: after all, these devices are not only ordinary atmospheric precipitation, but also hot combustion products. Such a combination can cause accelerated corrosion from any unprotected metal.

The principle of a chimney pipe deflector

The principle of operation of the deflector is based on the following aerodynamic principles:

When exposed to wind flow from top to bottom, the expiring combustion products through the lower ring of the hole begins.

If the wind begins to blow up, the gases begin to expire through the top ring canal.

If the wind stream is directed parallel to the horizon, then the removal of combustion products occurs through both holes.

The smallest thrust level of such a design shows if the wind stream is directed from the bottom up. Prevents the expiration of gases in this case the upper umbrella. In order to prevent operation interruptions - an umbrella can be manufactured in the form of two cone-shaped structures connected by wide parts. In this case, the negative moments of the work of the deflector are compensated.

How to make a deflector for chimney with your own hands

Understanding the principle of work of the deflector on the chimney pipe you can proceed to its manufacture with your own hands. The deflector installation process is as follows:

After the formation of the lower glass, three or four racks are fixed on it.

To the bottom of the deflector is attached the upper cylinder. This can be done with the help of clamps.

Through brackets on the top of the deflector, the cap is fixed.

When installing a round-cross-sectional deflector on a square chimney, transition nozzles are used.

If the chimney pipe has a too large cross section (for example, a fireplace tube), then a set of supports made of steel are used for its connection with a deflector.

Purpose and Device Flowage Pipe Chimney

Oddly enough, but the weather, and more or rather, the fluorca is not only a home decoration, but also a device that provides an increase in thrust in chimneys of heating systems without using additional power sources, such as electricity.

This device protects the headband of the chimney pipe from the wind.

The fluorca consists of a lid of the conical shape, the screen that has a configuration of the semi-cylinder and, actually, the fluger. All device is fixed on the bearing or on a freely rotating axis.

Fluugarca is a moving device that changes its position depending on the direction of the wind flow and thereby protects the tip of the pipe from the impact of the wind.

In the wind - the fluorca unfolds to its flow by a convex half-cylindrical part. The wind goeshes the tip head and enhances the thrust in the chimney system, producing a kind of "SUPPLC" products of combustion.

Fluugark can be used in a variety of systems. A significant disadvantage of such devices is the rapid wear of moving elements that provide free rotation. In addition, in the winter in the rolling parts of the flugark can accumulate and freeze moisture, which significantly reduces the effectiveness of its work. During the periods of strong frost moisture, the fluger will stop rotating, which will lead to the opposite effect: the wind will start the air and blend it into the pipe and the boiler! As a result, such devices are not recommended to be used in areas with harsh climatic conditions. In this case, classic deflectors are better used on chimney pipes.

The use of deflectors and voaging will ensure efficient operation of thermal systems of your structure.

The smokers are the same important elements of heat plants, as well as furnaces, fireplaces and boilers operating on organic fuel. They are simply necessary: \u200b\u200bfor the proper functioning of the heating system, it is necessary to provide the optimal and output of combustion products. If the chimney for the heat generator is made and designed competently, it should provide a stable and natural output of combustion products, working without chance. In the other case, if these rules are not observed, you can create special blockage on the path of wind threads and use such a device as a chimney deflector. It will give the opportunity to restore and increase the craving, as well as continue the combustion procedure.

Causes of shrinking pipe

The main causes of smoke, as a rule, can be called three points:

• Incorrectly chosen (very small) size section of the pipe for chimney.

• Folding into the smoke tube (which is very often at the time of the impustary and strong wind), and besides this, the pressure on the smoke, which comes out of the chimney pipe, as a result of which the thrust thoroughly falls and some smoke remains inside.

• A small height and illiterate installation of the chimney on the roof.

All about the deflector

Deflector's purpose

- Deflectors should ensure the gain of thrust using the deviation of the air flow. Different designs of deflectors carry out the same procedure - the occurrence of a field of low pressure when flow around the barriers to the surrounding air. At the same time, the wind does not disturb the craving, but only enhances it.

- With the help of a deflector, it is possible to achieve a solid increase in the PDD of the pipe (up to 20%).

- Deflector on the chimney of the gas boiler, fireplace, furnace ... Protects the chimney channel from snow and rain, as well as different garbage, etc.

Tip: Installation of the deflector for chimney will give an excellent thrust increase if the chimney is not direct, but with two or four turns.

Using a deflector

Today, the smoke of the chimney is used as special air emission systems from these structures:

- garbage chute:

- discharges of emissions of all exhaust combustion products (from the operation of the generator, gas column, solid fuel boilers ..);

- collective and individual chimneys;

- individual and collective channels of natural ventilation.

Deflector options

There are deflectors of a variety of designs:

• grigorovich deflector;
• cahga's deflector;
• defl. N-shaped;
• defl. Star (Shenard);
• round deflast. "Volper";
• Astato open deflector.

Structure of deflector

It consists of such components:

- umbrella - or cone-shaped;

- lower cylinder;

- Diffuser - upper cylinder.

Installing a deflector for chimney

- The deflector is made of galvanized iron.

- The work of the lower cylinder, usually performs a ceramic, metal or asbestos-cement chimney to which the deflector itself is installed.

Tip: Diffuser, Cap and Reverse Cone can be collected independently on aluminum rivets or weld special. contact welding with a rivet.

Important: patterns of elements depend on the chimney diameter. Pipes, but the proportions of the dimensions of the deflector parts must be adhered to strictly.

How the deflector works

The deflector works in this way:

1. Air flows, when hit along the walls of the upper cylinder, enhance it from all sides.
2. Another part of the air flows, moving along the surface of the cylinder, turns up and immediately sucks the whole smoke, departing from the pipe both from below, and on top.
3. Movement in the pipe becomes very active and the thrust increases accordingly.
4. When the wind does not blow in the horizontal direction, but from the bottom-up, or on top-down, at an angle, then the chimney deflector helps to increase the thrust. The wind through the gaps passes into the upper cylinder and sucks the smoke that enters the pipe.
5. The only minus that is present in all deflectors is observed at that time when the wind blows: vortices, slowing and preventing the yield of smoke are formed.

Tip: If the bottom wind occurs, you need to put a reverse cone under the cap (umbrella), it is possible to reflect the air flows with smoke, in particular, to dissect and remove them.

Working deflector with windproof system

The chimney deflector with windproof (or fluger) works like this:

— When the wind direction changes, the fluger turns, and then together with him begins to spin and the curtain flashes the smoke tube from the wind - so smoke can come out without obstacles to the fraction of the chimney.

- Wind streams, sliding at the top of a semi-cylindrical screen, suck it, thus enhancing thrust.

Tip 1: so that the wind vane - easily and freely rotated together with the canvas, the bearing of the deflector must be constantly lubricated, and in the winter time to knock off the nondes arising from the condensation of the steam, at the same time emerging with smoke from the chimney pipe.

Tip 2: The deflector on the chimney with windproof function is good to buy and use in southern, warmer areas where winter is not so severe, but much more sunny days.

Features of using deflectors

• Fixing the chimney deflector having a round cross section to rectangular or square smoke brick pipes, occurs with the help of nozzles (transition).

• The transition from square forms of pipes to the round sections of the deflector occurs only with gradual brickwork.

• If the chimney with a considerable section, then the deflectors attach special backups or broken steel legs.

• Deflectors need to be used for those fireplaces that work only on solid fuel.

The chimney system is one of the key elements of any thermal installation, it is not inferior to other elements of the design. In order for the heating equipment to work correctly, the system should be ensured by a stable influx of air and the output of fuel combustion products. Usually, the chimney is used for these purposes, which, with competent design and installation, will allow the system to fully work on a natural line, all the remains in the atmosphere.

In some cases, the arrangement of a full chimney is impossible, but the need for thrust because of this does not disappear. In order for the system to continue to function, you need to install a deflector on the gas pipe, which will provide normal traction and will allow thermal equipment to work. This article will talk about deflectors and their features.

Causes of chimney pipes

Often, when using the chimney, such a phenomenon is found as the smoking of the pipe, which can occur for the following reasons:

1. Strong air gusts aimed into the chimney. As a result, there is a serious obstacle that does not allow smoke to enter the atmosphere. The thrust is reduced, and smoke remains in the system, sooner or later, starting to fall into the building.
2. The weak work of the chimney can be explained very simple - if the design was initially calculated incorrectly, then there can be a speech about normal operation. For example, the installation of too narrow chimney will necessarily lead to a weak traction and insufficient allocating combustion products. The same can be said about the lack of height or improper placement of the pipe on the roof.

If from the second reason you can get rid of the design stage, if the chimney is not yet installed, then with the first reason it will be necessary to encounter, so the need to install the chimney still remains.

Application of deflectors

The main quality of deflectors, for which they apply - the ability to strengthen the craving due to the leading of external air flows. Regardless of the design, any deflector works on a single principle - the intercom of the air creates a low pressure zone, due to which the thrust increases in the chimney. A good deflector can increase the efficiency of the smoke system by 20%.

In addition, the deflector has an additional feature that occurs indirectly - an obstacle to the chimney is prevented from entering atmospheric precipitation and various garbage.

The design of a simple deflector includes two cylinders, one of which is lower, and the second from above, and a protective cone, also called an umbrella. The lower cylinder is usually part of the chimney made of metal or asbestos cement. For the manufacture of deflectors themselves used galvanized metal.

There are several standard options for deflectors:

• Cahga's deflector;
• "Volper" with a round corps;
• Grigorovich deflector;
• Open deflector Astato;
• N-shaped;
• Star-shaped "SHENARD".

Different types of deflectors are used in the following types of designs:

• Collective and private ventilation mines;
• Collective and private chimneys;
• Gas removal systems and their combustion products;
• The trunks of garbage disposal.

Installation of a deflector for chimney do it yourself

Not only rivets can be used to build structural elements, but also contact welding - not a noticeable difference in the end. When working it is important to correctly choose the ratio of the size of the details of the deflector so that it can then be installed on the chimney.

The principle of operation of the deflector assembled in this way looks like this:

• Any air flow trying to pass through the upper cylinder meets the obstacle and bypassing it;
• The air flows passing over the cylinder are folded up and pulling the smoke from the pipe;
• Due to the piping in the pipe, the movement is intensified, so the traction becomes an order of magnitude more.

Even if the wind streams are directed not strictly horizontally, and on another trajectory mounted on the chimney pipe cone still performs its functions. It turns out that the wind turns out in the upper cylinder, passing through the gaps of the structure, as a result of which the smoke sucks out.

Installation of a disflector with windproof device

The deflector with wind protection is mounted as follows:

• Two bearing and vertical axis are recorded in the chimney on two levels;
• A semi-cylindrical shirma, a canvas of the fluger and the roof of the structure is consistently installed on the axis.

The principle of operation of this type of systems is as follows:

1. When the wind direction changes, the fluger is turned off and pulls the curtain covering the chimney from the wind. As a result, smoke can be released from the leeward side of the chimney at any time.
2. Air flows are tangent over a half-cylindrical screen and pull up smoke, increasing the craving in the system.

To increase the efficiency of the design, it is necessary to periodically lubricate the bearing of the deflector, and during the cold season, it is also eliminated to be removed, which occurs in the design due to condensate. Taking into account the last nuance, it can be said that such a nozzle on the chimney pipe from the wind will be able to effectively protect only those designs that are located in the warm regions.

Features of deflectors

By installing a deflector on the pipe, you need to know about some features of its application:

1. To secure on the chimney of a square or rectangular shape, a round deflector, you need to use special transitional pipes.
2. If the set chimney has a large cross section, then the deflector needs to be installed on special legs or use steel backups.
3. By installing the transition from a square chimney to a round deflector, you need to take into account the gradual science of brickwork.
4. Installation of deflectors is required only for heating equipment operating on solid fuel - in other cases, any protective cone on the pipe will be useless.

Knowledge of these nuances will allow you to choose the optimal pipe deflector for the chimney and set it so that it can increase the efficiency of the entire heating system.

Conclusion

The installation of a deflector on a pipe of solid fuel heating equipment makes it possible to increase the craving in the system and simplify the output of combustion products into the atmosphere - and this not only improves the quality of the system, but also prevents smoke to get into a residential premises where it can harm human health.
