Boiler/Burner Combustion Air Supply Requirements and ...

Boiler room temperatures at the burner fan inlet should be controlled between 50°F and 100°F in order to limit variability in the amount of combustion air delivered to the burner. The venting system can affect both the amount of air required in the boiler room and the performance of the combustion air fan regarding its ability to deliver the required amount of air flow.

Adjustment of the burner affects the amount of CO produced. Insufficient primary burner air increases CO production. Restricted air inlets often produce a noticeable disruption of the flame and a change from blue to yellow. Another cause of insufficient primary air and incomplete combustion is excess gas flow to the burner.

Optimal Combustion Process - Fuels and Excess Air

Even so-called "on-ratio" combustion used in boilers and high temperature process furnaces incorporates a modest amount of excess air - 10 to 20% more than needed to burn the fuel completely. If insufficient amount of air is supplied to the burner unburned fuel soot smoke and carbon monoxide are exhausted from the boiler.

Primary air is the air that is mixed with the fuel at or in the burner. Secondary air is usually the air that is brought in around the burner. Tertiary air is usually the air that is introduced downstream of the secondary air or through other openings in the combustion furnace. Good combustion requires: the proper proportioning of fuel and air
