Read MoreBoiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
