ABSTRACT:
A process for providing pressurized, pulverized coal for use in combustion or gasifying of coal by the fluidized bed or suspended particle combustion principles which comprises the steps of introducing lump coal, of stoker size to run of mine size, into a low energy liquid circulation stream; transferring the lump coal to a high energy, high pressure, liquid circulation stream; separating the lump coal from the high energy liquid circulation stream by lifting the coal through a free liquid surface, said high energy liquid draining from the coal by gravity; directing the coal by gravity transfer to a continuous mechanical dryer for removal of surface liquid; gravity transfer to a coal crusher for major size reduction; gravity transfer to a coal pulverizer for size reduction necessary for the gasification processes; transfer of pulverized coal by gas circulation from the pulverizer to a cyclone separator, said circulating gas used in the pulverizer for coal particle classifying; and final injection of the pulverized coal to a fluidized bed or suspended flow coal gasifier or any pressurized combustion chamber, and apparatus for carrying out the process comprising a combination of known components.
