Abstract: The method involves drawing off of a solid flow by a down pipe (6), and fluidizing the solid flow on a base (8) of the down pipe by a supply of carrier gas. The solid flow is transported to a high level by an ascending pipe (9) branched off by the down pipe, and dimension of the solid flow extracted by the ascending pipe is varied by variable supply of the carrier gas. The level of the flow or solid stock in a solid container is used as a controlled variable, and a volume flow of the carrier gas is used as a correcting variable of a control loop. Independent claims are also included for the following: (1) a method for regulating a temperature and/or mixing ratio in a mixing vessel (2) a device for regulating a level and/or solid stock in a solid container.

Abstract: The invention relates to a method and a plant for the heat treatment of sulfidic ores, in which solids are heated to a temperature of approximately 450 to 1500° C. in a fluidized bed reactor ( 1 ). In order to improve the energy utilization, it is proposed to introduce a first gas or gas mixture from below through a gas supply tube ( 3 ) into a mixing chamber ( 7 ) of the reactor ( 1 ), the gas supply tube ( 3 ) being at least partly surrounded by a stationary annular fluidized bed ( 35 ) which is fluidized by supplying fluidizing gas. The gas velocities of the first gas or gas mixture as well as of the fluidizing gas for the annular fluidized bed ( 35 ) are adjusted such that the particle Froude numbers in the gas supply tube ( 3 ) are between 1 and 100, in the annular fluidized bed ( 35 ) between 0.02 and 2 and in the mixing chamber ( 7 ) between 0.3 and 30.

Abstract: For dividing a stream of solids, which is withdrawn from a fluidized-bed tank, the stream of solids is discharged via a first downer and fluidized at the bottom of the first downer by supplying a fluidizing gas, wherein at least part of the stream of solids is conveyed to the top via a first riser branching off from the downer, wherein the remaining part of the stream of solids is discharged via a second downer adjoining the first downer and is fluidized at the bottom of the second downer by supplying a fluidizing gas, and wherein at least part of the stream of solids is conveyed to the top via a riser branching off from the second downer.
