Coal boiler vs wood boiler efficiency | Hand Fired Boilers

13/11/2018 · If your wood is guaranteed perfectly seasoned and is a mix of good quality hardwood its efficiency in burning will be about the same as for anthracite coal. But wood is almost never perfectly seasoned (and sometimes it isn't even close to this goal), and is also almost never a perfect mixture of average mixed quality hardwoods either.

efficiency of coal fired boilers - Zozen Boiler

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.
