Coal fired boiler - Guideline for energy efficient

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.

Jul 15, 2018 · The distribution profiles of combustion temperature, heat flux, CO mass fraction and unburnt char particles were selected to analyze the boiler performance under different cases. Results show that boiler performance deteriorates evidently when PAR is increased to 0.425, and the overall heat flux decreases by 37.0 MW.

Fuel used in the boiler should be combusted completely to get complete heat of fuel. Due to low oxygen supply or uneven oxygen supply there may be changes of incomplete combustion of fuel. Incomplete combustion will reduce boiler efficiency drastically, it must be checked regularly and controlled by proper combustion system.

How to Run a Coal Fired Boiler at the Best 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.
