How to Run a Coal Fired Boiler at the Best Efficiency

Jul 05, 2009 · 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.

AVAILABLE AND EMERGING TECHNOLOGIES FOR REDUCING

Pulverized-coal (PC) boilers offer a more efficient alternative to stokers for burning coal. PC boilers are used in large ICI units. In PC boilers, the coal is pulverized to very small particles in large devices called pulverizers or mills. These coal particles are then blown with air into the boiler through a "burner," where they are then
