Chimney for the furnace: device and circuit

The chimney acts as an irreplaceable component of the heating system. From how correctly it will be possible to build it, the efficiency of heating and safety of operation will depend. That's why its device needs to ask before it is built. Choosing a chimney for the furnace, you can consider several varieties of such designs, they can be:

• Walled;
• Nasadnymi;
• Indigenous.

The technology for fitting these chimneys is similar, but there are some differences. It is important to consider that each design can be used in a particular case.

Construction of a wall chimney

The wall chimney for the stove is part of the wall and passes through its inner space. It is important to consider before planning the construction works that the wall should be made of red brick. Sometimes there are surfaces of wood, but the place under the chimney in this case should be faced with red brick.

Considering such a chimney for the furnace, it should be noted that the walls of the node should be more than 1/2 bricks in thickness. In the place where the furnace is connected to the chimney, there are hinged sleeves, which are elements having a horizontal direction. They act as part of the smoke channel.

Channels are laid out of bricks, but sleeves along the length should not be more than 2 m. For hoses, steel pieces are used in the form of corners, which are laid in the oven at the stage of its erection. The outlet channel must be 6,5 cm below the steel corners. The ends of the corners are sealed in the chimney, and in the pipe they should be located at the same distance, that is, 6.5 cm.

Corners usually have a horizontal arrangement or a slight slope, directed toward the removal of smoke. Spreading such a chimney for the oven, you will have to form the walls of the sleeve, the thickness of which is equal to a quarter of the brick. This indicates that the products should be laid on the edge. It is important at the same time to ensure vertical ligation of the joints.

The unit assembly assumes the presence of a base that is on the top of the furnace or on the floor. The foundation will have the appearance of a platform filled with concrete. It must have an equal basis. After the laying of the first row begins, use is made of clay mortar. It is important to align the corners. Then further brick laying is carried out, at which an opening is made in the chimney with a door for preventive cleaning. If it is a private house, then the galvanized sheet steel should be laid in front of the oven, the same technology needs to be acted upon by the chimney hoses.

The device of the root chimney

Chimneys for sauna ovens are presented today in several varieties. They can be indigenous. In this case, the node will have a foundation for which the pit is prepared, taking into account the dimensions of the chimney. The internal space of this part of the furnace must be 135 x 260 mm, only under such conditions it will be possible to guarantee smoke evacuation and normal draft.

It is necessary to damp the foundation pit by 30 cm. The bottom should be filled with crushed stone or gravel, which is covered with sand. Layers should have approximately the same thickness, which is 15 cm. The pillow is compacted and well leveled.

The sauna stove, the chimney of which will have a radical construction, assumes the presence of leveling screed, which is prepared from cement mortar. Make the composition must be liquid, which will ensure the smoothness of the surface. Once the screed has dried, you can start laying the chimney.

Recommendations of a specialist

First, the first layer of brick is arranged, then you can start to remove the corners using the building level or the plumb line. The laying should be carried out to the level where the hose is to be connected to the furnace. Its fixing is carried out by metal corners, the second ends of which must be installed in the chimney, as in the above-described case. Place the joint with a clay solution. Masonry of products should be carried out with a bandage of half a brick.

When should I select a chimney flue

Chimneys for sauna ovens can also have a nasal structure. It can also be used for solid fuel boilers. Installation is carried out directly on the stove or fireplace. Among the advantages should be allocated the possibility of using asbestos-cement or steel pipes.

Arrangement of a perforated chimney

Boilers, ovens, chimneys of which usually have an embankment design, can be installed independently. That is why before starting work it is necessary to take an interest in the device of this unit of the heater. The difference in technology in this case is only that the chimney will be adjacent to the stove.

The system will not have a foundation, but the heater itself will act as the basis. However, there are still some tips that need to be applied when building a chimney independently. The design should be brought to the building's skate, and when choosing the height of the pipe, be guided by the distance to the ridge. The most suitable parameter in this case is 0.5 m above the ridge, if the distance to it is less than 1.5 m.

If there are nearby wooden buildings or trees that could be in contact with the pipe, you can build the unit with a ceramic pipe, which will reduce the risk of a fire. At the end of the chimney, you should install a visor that protects the pipe from rain and debris. The furnace chimney scheme assumes the presence of a grid, which is located inside the chimney, at its end. This will eliminate the emission of unburned particles, for example paper.

Conclusion

Quite often for stoves, coaxial chimneys are also used , which can have a knee with a right turn angle. The design should have a tip, connecting clamps and decorative lining. The device should be started by selecting the place where the pipe is taken to the street. It should be closer to the heater.
