The largest pressurised fluidised bed power plant in operation is a 360 MW unit in Japan. This plant, with a supercritical boiler, has a claimed efficiency of 42%. Although commercial fluidised bed power plants with capacities of over 400 MW are available, the units have not proved as efficient as supercritical PC power plants for coal combustion. Their sulphur and nitrogen oxides emissions, though lower than from a PC power plant …

Coal-Fired Boiler - an overview | ScienceDirect Topics

Jul 05, 2009 · Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

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.
