Combustion of Coal
Oxy-fuel combustion is a pulverized coal combustion process practiced in coal-fired power plant. In a traditional power plant, the pulverized coal used for fuel is fired and the oxygen comes from injected air. Pulverised coal combustion technology is mainly used for steam generation in the power plant, where most of the cases suspended coal
