Boiler Efficiency - an overview | ScienceDirect Topi

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.
