One of the most essential parts in the chimney vent is Normal operation of your furnace will not be possible without good traction means by a sufficient air flow and the correct output gases. All this is provided by a qualified and qualitatively manufactured chimney. However, there are a number of factors that significantly worsen traction and reduce the efficiency of the furnace. These are precipitation, strong wind, and debris that clog the chimney and interfere with its normal operation. Chimney, begins to smoke heavily.

Consider how a deflector for the flue pipe
presence good chimney contributes to the stability and natural products exitGoran - an important condition for operation of the heat generator, operating without pressurization. If there is no such device, then a deflector for the chimney should be used. This device creates an obstacle in the path of the air flow formed by a gust of wind.
Such a simple but effective structure, like a deflector, perfectly protects the chimney from blowing wind, precipitation and debris. To its functions, one can also include a good removal of smoke from the pipe.
Before installing the deflector on the chimney pipe, it is necessary to familiarize yourself with the principle of its operation
According to specialists, after the deflector installation, the efficiency of the heating system becomes higher by 15-20%.However, this device will operate only if the chimney is installed without errors and flaws. Its height should be sufficient, and the cross-section correctly selected. Of no small importance is the location of the pipe on the roof.
The principle of operation of the deflector in the chimney:
- upper cylinder wall prevents air flow, which in a collision with him just his girdle;
- Some of the air coming from the common jet rises rapidly up the cylinder and finds smoke coming from the chimney;
- intensively moving in the pipe smoke sucked outside air, then it becomes much more productive and increases traction.
- Regardless of where the air flows to the deflector are from, the required draft in the heater will be of good quality.
There are gaps in the upper cylinder through which smoke is sucked in by air. However, at the same time when the wind from below, the air flow can form under some twists deflector hood that will retard and prevent the exit of smoke from the chimney. This defect, unfortunately, is inherent in all deflectors. But many solve it by installing under the umbrella deflector upside-down cone. Such a simple adaptation will lead to reflection, dissection and removal from the chimney of air masses mixed with smoke.
Simple deflector on the pipe with your own hands: calculation and drawings of the product
If your chimney is not fully completed and from time to time you see that there are problems with the discharge of combustion waste, you can try to solve this problem in two ways: to buy a ready deflector, Corresponding to the parameter of your chimney, or to make a homemade device.
If you have chosen the second solution of the problem, then first you need to draw a drawing of the deflector, which you will put on the chimney. Without this type of design, you can not be taken for work. The design diagram must be present.
Specialists recommend additionally to calculate the deflector before installing
Only after you carefully measure all the parameters and draw up a competent drawing of the device, you can proceed to practical actions. In addition, before you start to manufacture the deflector on the chimney, you need to prepare some materials and tools.
For the manufacture of the deflector you will need:
- Stainless steel sheet, 0.5-1 m in size. If there is no stainless, then it is suitable and galvanized, although it will serve less.
- Shears for metal;
- Riveter;
- Drill;
- Thick cardboard;
- Drill;
First, all the details, strictly in size, are drawn on a cardboard in full size, and then cut out. Paper elements are assembled as they are required to be in the finished product. If everything is assembled correctly, then all the same actions can be done with a sheet of metal. To do this, put the paper elements on the metal and draw a marker. Then we cut out all the details with scissors. In places of cutting, pieces of metal should be bent by pliers and taped with a hammer. The diffuser is made from a piece of metal rolled up by a cylinder. In the edges holes are drilled, the edges are fastened with rivets, bolts, welding to choose from. Similarly, we make an external cylinder. Beyond that, make a hood made of cone-rolled metal. In the next step, we cut 3-4 strips from the sheet, about 20 cm in length, about 6 cm in width. We fold the sides and beat them with a hammer. In the hood at a level of 5 cm from the edge, drill holes for the bolts. Strips attach to the hood and bend them in the shape of the letter P. Cramped umbrella attach to the diffuser. At the final stage, the resulting design is inserted into the outer cylinder.
How to make your own hands deflector Grigorovich
Among the devices for chimneys should be mentioned deflector Grigorovich. This design allows you to increase traction by 20% and improve the energy efficiency of the solid fuel boiler.
Produce your own hands deflector Grigorovich possible if pre-acquainted with all the nuances of this process
If you collect deflector Grigorovich, the need to supplement the instrument inverted cone. Then the protective umbrella is made in diameter larger than this cone by 3-4 cm. Having manufactured both parts, it is necessary to enclose the smaller one in a bigger one and carefully draw a marker. After this, on a larger cone, we make incisions before the line, resulting in the order of 8 strips located at the same distance. Strips bend inwards. With their help, our return cone is securely fixed in a protective umbrella without welding. When using this cone, the mounting of the umbrella to the diffuser is best done with the help of pins.
The received design will be distinguished by high reliability, it is not afraid of strong gusts of wind and will serve you for a long time.
deflector to the chimney consists of:
- inlet pipe;
- Enclosures;
- Diffuser;
- Umbrella( wolf);
- Brackets.
To install this deflector on the chimney, you need to drill 3 holes exactly at one level. The device is inserted into the pipe and bolted. Then we assemble a bearing, a protective cap, a comfrey, a cylinder and a weather vane on the axle. We fasten everything together with rivets. In order for the deflector and the weathervane to function normally, it is necessary to monitor the condition of their bearings. It needs to be well lubricated, otherwise rotation will be difficult. Take care that in winter there is no icing of the structure.
Practical deflector for the flue gas boiler
The heating system must necessarily include a channel for removing smoke from the furnace. The task of this device is to remove harmful combustion products. Its proper functioning affects the operation of the heating equipment.
Choosing deflector to the chimney, you must take into account the quality and practicality
very important to follow, to ensure that the system was intact. If this is not adhered to, the design will not work properly. The wind will blow out the boiler and the room will cool down.
When a strong gust blows the flame of the burner, the gas boiler will go out. In order for this not to happen, it is necessary to take appropriate measures - to install the deflector on the chimney.
What is the deflector to the chimney:
- Protect smoke ducts from precipitation;
- Eliminates the occurrence of debris in the boiler;
- Will cover against strong gusts of wind;
- Will improve the draft of the boiler.
Externally the deflector looks like a hood, put on a smoke exhaust pipe. This construction should be made with a build-up. It will help to protect the boiler from blowing. In some cases, where there are often strong gusts of wind, use the H-shaped deflector.
What is the deflector on the chimney( video)
The deflector is a device installed in the chimney head. The task of this device is to improve traction and protection from debris and precipitation. The deflector for the chimney can be divided into several varieties. This product can be with a flat top, or it has the shape of a semicircle, which opens the lid.
