  • Boiler Efficiency - an overview | ScienceDirect Topics

    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. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.

    • Is a high efficiency, condensing gas boiler the best

      Aug 13, 2018 · For example, a 30-year old boiler might be 70% efficient, meaning that for every dollar you spend on gas, 30 cents of heat escapes through the chimney or vent pipe. In comparison, a condensing boiler may provide up to 96% efficiency, which means that only 4 cents of heat escapes. That’s a big difference!
