Abstract
Dry coal powder is fed to a high-pressure coal gasification reactor from a high-pressure chamber in inert gas. The powder is introduced in the chamber via a centrifugal pump having an inlet tube passing through a wall of the chamber and a rotor inside the chamber, which rotor throws the powder into the chamber through radial nozzles by centrifugal force. Gas leakage from the chamber through the centrifugal pump is created to prevent blockage.
