Coal-Fired Boiler - 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.

Understanding Coal Power Plant Heat Rate and Efficiency

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.

Conversion of Existing Coal-Fired Boilers to Natural Gas

Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency. This efficiency loss is offset somewhat by the lower amount of excess air required to burn natural gas. Boiler efficiency decreases are to be expected in the 3% to 4% range, depending on the current fuel and boiler …
