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. There are a few minor losses in boiler which can also

Conventional Coal-Fired Power Plant - an overview

A conventional coal-fired power plant with post-combustion capture has to separate carbon dioxide from a flue gas mixture in which there is a large amount of nitrogen. The oxyfuel process, by removing the nitrogen at the start, so that coal burns in oxygen instead of air, sidesteps this problem because the flue gases from the combustion process
