ABSTRACT:
A plant for producing metal oxide from metal compounds includes a fluidized-bed reactor in which the metal compounds are heated by a combustion of a fuel to produce metal oxide. The fluidized-bed-reactor reactor includes at least one gas supply tube at least partly surrounded by an annular chamber in which a stationary annular fluidized bed is disposed, and a mixing chamber disposed above an orifice region of the gas supply tube. A gas flowing through the gas supply tube entrains solids from the stationary annular fluidized bed when passing through the orifice region.
