Therefore, in practice more air than ideal must be supplied to burn all fuel completely. The amount of air more than the theoretical requirement is referred to as excess air. Power plant boilers normally run about 10 to 20 percent excess air. Natural gas-fired boilers may run as low as 5 percent excess air.

1.4 Natural Gas Combustion

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas

Why do boilers leak carbon monoxide? How can this be

Oct 27, 2016 · Boilers don't exactly “leak” carbon monoxide, they actually create it. Without getting overly technical, CO is a product of incomplete combustion due to insufficient availability of oxygen.


The burning of natural gas is cleaner than the burning of oil and coal. When gas is burned with insufficient combustion air some volatile hydrocarbons can be created, which could become a safety hazard; care should be taken to avoid dangerous conditions.
