      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
