摘要： The present invention relates to a method and a plant for the heat treatment of solids containing iron oxide, in which fine-grained solids are heated to a temperature of 700 to 1150° C. in a fluidized bed reactor (8). To improve the utilization of energy, it is proposed to introduce a first gas or gas mixture from below through at least one gas supply tube (9) into a mixing chamber region (15) of the reactor (8), the gas supply tube (9) being at least partly surrounded by a stationary annular fluidized bed (12) which is fluidized by supplying fluidizing gas. The gas velocities of the first gas or gas mixture and of the fluidizing gas for the annular fluidized bed (12) are adjusted such that the Particle-Froude-Numbers in the gas supply tube (9) are between 1 and 100, in the annular fluidized bed (12) between 0.02 and 2, and in the mixing chamber (15) between 0.3 and 30.

摘要： 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.

摘要： The granular sponge iron is supplied to a roller press at temperatures of 600 to 850.degree. C. for molding the hot briquets. There is produced a strip structure of sponge iron containing formed hot briquets, which are arranged at a distance from each other. By smashing the strip structure, the hot briquets are separated from each other, so that fragments of the strip structure are obtained. The hot briquets and at least part of the fragments are cooled to temperatures in the range from 20 to 400.degree. C., and the cooled briquets and fragments are passed through a rotary drum. In the rotary drum, fine-grained fines of the briquets and fragments are produced. Subsequently, these fines are separated from the briquets and fragments, as they exhibit a pyrophoric behavior.

摘要： According to the invention, a fluidizing gas is introduced upwards into the fluidized bed (3) through a valve grid (2), said stationary fluidized bed (3) containing solids with different grain sizes. A supply pipe (10) is disposed in the area of the fluidized bed, the mouth of said pipe being located above the valve grid (2) and its outlet (12) leading outwards from the fluidized bed (3). Part of the solids located above the valve grid (2) is blown into the supply pipe by a gas jet (13) which is directed upwards and fed separately from the fluidizing gas and pneumatically evacuated from the fluidized bed through the supply pipe (10). Normally, the flow speed of the gas in the supply pipe is at least two times higher than the speed of the fluidizing gas in the fluidized bed.
