How to Run a Coal Fired Boiler at the Best Efficiency

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.

Boiler (Steam Generator) - Coal Fired Power Plant

A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam. Within this boiling process saturated steam is produced at a rate which can vary according to the pressure above the boiling water. The higher the furnace temperature, the faster the steam production.
