Valueinuse assessment for thermal coal. Dan J. Eyre, in The Coal Handbook (Second Edition), 2023 Boiler efficiency and carbon burnout. Boiler 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.
