1, the chimney height is not enough, which leads to low pumping force, especially when the air pressure is low, and advection wind may fall back from the chimney. The solution is to heighten the chimney or add a hood that can be adjusted with the wind;
2, chimney air leakage will reduce the pumping force, the corresponding method is to wipe a gap to block the air leakage;
3. When the stove is ignited, the smoke is poured out because the chimney suction has not yet formed. The longer the horizontal flue is, the slower the chimney suction will form, and it will be better to make the horizontal flue upward.
4. Add an induced draft fan to the flue.
Extended data:
If the exit of the chimney is a window, it is recommended to use iron sheet, which is made in the street. The style is a square iron plate with a round hole slightly larger than the chimney in the middle. Pay attention to the diameter of the chimney before buying. If the exit is on the wall, it is recommended to use mud-I feel that the gap is not very big and will not affect the appearance too much. Of course, white ash (lime) will do. That would be more beautiful!
This function is:
1, to prevent air from entering the furnace and destroy the stability of the atmosphere in the furnace.
2. Prevent the leakage of the atmosphere in the furnace, reduce the pressure of the atmosphere in the furnace and increase the consumption of the atmosphere in the furnace. If the atmosphere in the furnace contains combustible and harmful gas components such as CO, H2 and CH4, the gas will leak into the workshop, which will worsen the operating environment of the workshop.
