Introduction to Boiler Control Systems

The pulverized fuel system is nowadays universally used for large capacity plants and using low cost (Low grade) fuel it gives high thermal efficiency and better control as per the load demand. In a pulverized fuel firing system, the coal is reduced to a fine powder with the help of grinding mill and then projected into the combustion chamber with the help of hot air current.

CFBC Boiler vs Pulverized Fired Boiler

Dec 11, 2015 · In FBC boilers operating at ~850°C, there is an inherent lower production of NOx auto-matically, as the combustion temperature is low. Even In PF boilers, Flame temperature reduction from 1480-1500 to 1250° C will impact NOx generation by 10 fold. These boilers also offer a very convenient way of reducing the SOx emission within the furnace
