ABSTRACT:
Method and apparatus for introducing finely divided solids, especially particulate coal, into a gas-containing vessel, utilizing a centrifugal pump having a feed inlet and a rotor. The rotor is surrounded by a second gas of lower density than the first gas in the vessel in order to reduce friction. The second gas can be at a lower pressure or a lower molecular weight than the first gas, low pressure hydrogen being preferred.
