combustion air pre heater to save boiler energy

Combustion Air Requirements:The Forgotten Element

Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.
