Atmospheric chimney — is a vertical pipe or system of pipes designed to remove flue gases from heating equipment (boilers, fireplaces, etc.) into the atmosphere due to natural draft.
Atmospheric chimney: operating principle
In atmospheric chimneys, draft is created by the difference in pressure between the hot gases inside the chimney and the cold air outside. The efficiency of the chimney depends on its height, the temperature of the exhaust gases and the diameter of the pipe.
This type of chimney does not require fans or other mechanisms to force the removal of combustion products, but may be less efficient than chimneys with forced draft, especially in adverse weather conditions.
Forced draft chimney: what is the difference
It is a flue gas exhaust system that uses a fan or turbine to create draft and efficiently remove combustion products. Unlike an atmospheric chimney,
