Pulverized Fuel Boilers | Газогенераторы МСД

Pulverized fuel boilers can be categorized as: 1. Industrial and small utility. 2. Large utility. Industrial PF boilers, which range from 100 to 400 tph, or 25 to 100 MWe, have practi­cally been superseded by CFBC. Hence reheat and nonreheat models covering 100-250/ 300 MWe fill smaller utility and larger industrial needs.
