Steam Calculators: Boiler Calculator - Energy

As a safety factor to assure complete combustion, boilers are fired with excess air. One of the factors influencing NOx formation in a boiler is the excess air levels. High excess air levels (>45%) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.

A clean and tidy boiler room, particularly in the area of the combustion air intakes and the burner air inlet damper, is paramount in maintaining proper combustion. Such things as newspapers or animal hairs on fan inlet screens, dirt-encrusted fan blades, and birds' nests in unprotected stacks have all been seen to contribute to sooting and/or the generation of carbon monoxide at various times.

17/3/2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
