  • Calorific Value of Fuels: Definition, How to Calculate

    A bomb calorimeter was used to determine the calorific value of a sample of coal and the following readings were recorded: When the fuel is fired in a boiler, the calorific value given by bomb cannot be realised in furnace because the water vapour cannot give up its enthalpy as it does in the bomb. Also the bomb works at constant volume while Get Price

  • Boiler Efficiency - an overview | ScienceDirect Topics

    The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.Get Price
