Pulverized coal boiler - coal powder boiler, coal fired boil

Pulverized coal boiler is a kind of industrial boiler or power plant boiler that produces thermal energy by burning pulverized coal. Coal is ground to the size of a fine grain, mixed with air and burned in the flue gas flow. It is also known as pulverized coal furnace, powdered coal boiler or coal powder boiler.

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.
