Centrifugal pump for feeding solid particles to a pressurized vessel and process for feeding solid fuel to a high pressure gasification reactor.

摘要

Centrifugal pump for particulate matter, e.g. pulverized coal, comprising two discs being kept at a distance from each other. The distance (d) between the two discs decreases as a function of the radius (R) of the discs in such a way, that R x d is kept constant. Process for feeding pulverized coal to a high-pressure gasification reactor using this pump.
