How to Run a Coal Fired Boiler at the Best Efficiency

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.

Coking – Coking or coal pyrolysis is the way coke is produced by heating coal in an oxidation free atmosphere. Flue gases at temperatures between 1150°C and 1350°C heat up coal indirectly to 1000-1100°C for 14-24 hours. At the end of the grate, coke is fully carbonised and it is quenched mostly by water, or by inert gas. Air cannot be
