Abstract

A plant for the heat treatment of solids containing iron oxide. The plant includes a reactor including a fluidized bed reactor. The reactor includes a gas supply system disposed in the reactor, a stationary annular fluidized bed which at least partly surrounds the gas supply system, and a mixing chamber. The gas supply system is configured so that gas flowing through the gas supply system entrains solids from the stationary annular fluidized bed into the mixing chamber.
