Abstract
Combustion gases from combustion of a coal-in-oil fuel mixture are used as an inert carrier gas in a fluid energy pulverizer used in the formation of the fuel mixture. A portion of the hot combustion gases is separated, cooled and compressed and passed to a heat exchanger where that portion is heated by the remainder of the combustion gases, the hot, pressurized portion led to the fluid energy pulverizer for use as a carrier gas for pulverizing of further coal.
