Combustion Air

CFW provides centrifugal fans and blowers to supply air for burning in boilers, kilns and ovens. If the combustion air fan supplies too little air, fuel will yield less energy than it otherwise would. Inadequate combustion air supply can also result in greater fouling from soot in boilers, or the generation of excessive carbon monoxide.

It is important to note that modifications to a combustion system, or poor maintenance, can also lead to a lack of combustion air. Anything that causes a pressure drop in the air supply to the boiler, including the installation of new exhaust fans in the boiler room without adding makeup air capacity, reduces the effective capacity of the combustion air fan.
