Abstract
A centrifugal pump for feeding pulverized coal into a reactor of a high pressure coal gasification system is disclosed. The coal is pulverized and fed by conventional means into a hopper wherein that coal is mechanically pumped, by a modified screw which compacts the coal and releases entrained air and gases from that coal, to an impeller which serves to centrifugally sling the coal at high velocity into the reactor. Gases of the required type, pressure and quantity are combined with the coal at the point at which the coal is slung from the impeller in such a manner that the coal sufficiently dispersed and mixed with those gases and in proper form for gasification.
