CENTRIFUGAL PUMP FOR THE SUPPLY OF FINELY DIVIDED SOLIDS AND PROCESS FOR THE GASIFICATION OF COAL PARTICLES

摘要

Centrifugal pump for the supply of finely divided solids to a pressurized vessel (1), comprising a rotor (5, 6) which is rotatably arranged in the vessel (1) and a supply tube (7) for the supply of the solids in a carrier gas. The tube (7) is axially connected to one side (5) of the rotor. A discharge tube (8) for the carrier gas is connected to the other side (6) of the rotor in line with the supply tube (7). The pump is very suitable for application in the gasification of coal particles. The coal particles are supplied to the gasification reactor with the aid of the centrifugal pump.
