FAQs

What happens if not enough combustion air?

The fire smokes when the air supply runs out and the combustion air source is cut off. There is incomplete combustion, and carbon monoxide is produced. The fire then goes out, but often before the flame detection system can act to close the fuel safety shutoff valve(s).

What causes poor combustion?

Inadequate air-fuel mixing, inadequate residence time, insufficient temperature, and little total extra air are the main causes of incomplete combustion.
