configuration while the boiler 10 was fired by coal feeders and four (4) bark chute openings evenly spaced above the feeders. Boiler 10 was designed to burn stoker coal and wood fuel on an air cooled traveling grate. Both boilers 1 and 2 were designed to generate 110,000 pph of steam flow, while Boiler 10 had an MCR steam flow rate of 225,000 pph.

Combustion Efficiency and Excess Air

Jul 05, 2009 · 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.
