A centrifugal pump for feeding pulverized material such as coal particles from a low pressure zone into a high pressure zone, said pump having nozzles mounted on a rotor. The pulverized material is ejected into the high pressure space through the nozzles, and gas is supplied to the nozzles to control the flow rate of the pulverized material. Devices are provided that ensure mass flow of the material through the nozzles, even if the nozzles have a short length.

A centrifugal pump for transferring solid particles from a low pressure zone into a high pressure zone comprises a centrifugal rotor and a housing that are each rotatable about a central axis. The rotor debouches particles into the interior of the housing and a screw conveyor is arranged in the housing for transporting particles along the inner surface of the housing to an outlet which is coaxial to the central axis.
