How to Calculate Boiler Efficiency, Boiler Efficiency

Combustion boiler efficiency generally describes the ability of a burner to burn the entire fuel into the boiler combustion chamber (furnace). The efficiency of this type is calculated from the amount of fuel that does not burn along with the amount of air combustion air (air excess). Burning boiler can be said to be efficient if there is no

Boiler Combustion | CleanBoiler.org

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.

In the U.S. an oil fired boiler is turned on and off by the aquastat control. The thermostat starts the circulator; as water temperature returning to the boiler drops it to the cut in temperature the aquastat turns on the boiler. For a warm air furnace the thermostat turns on the burner, the plenum heats up, and the fan limit turns on the blower.
