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.

Efficiency of a Stoker Stove Vs. a Hand Fired Stove | Coal

Nov 04, 2017· The coal stoker also tends to be all on or idle, and it is that idle position that is inefficient and losses out to the hand fired operated at a mid output but steady firing rate. The stoker should be more efficient than the hand fired in really cold weather when it runs more steadily at set firing rate.
