(EN) Treatment of granular solids in an annular fluidized bed with microwaves

Abrégé
(EN)
This invention relates to a method for the thermal treatment of granular solids in a fluidized-bed reactor ( 1 ), in which microwave radiation from a microwave source ( 2 ) is fed into the reactor ( 1 ), and to a corresponding plant. To improve the utilization of energy and the introduction of the microwave radiation, a first gas or gas mixture is introduced from below through a preferably central gas supply tube ( 3 ) into a mixing chamber ( 7 ) of the reactor, the gas supply tube ( 3 ) being at least partly surrounded by a stationary annular fluidized bed ( 8 ) which is fluidized by supplying fluidizing gas. The microwave radiation is supplied to the mixing chamber ( 7 ) through the same gas supply tube ( 3 ).
