How to Run a Coal Fired Boiler at the Best Efficien

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
