Abstract: This invention relates to a method and a plant for the heat treatment of solids, in particular for reducing solids containing iron oxide, in a fluidized-bed reactor (5, 30). For fluidizing the solids, fluidizing gas is introduced into the fluidized-bed reactor (5, 30) via distributor grates (7, 32). Between a solids feed pipe (37) and a solids discharge pipe (38) of the fluidized-bed reactor (5, 30), the solids pass through multiple chambers (8, 34) each with a distributor grate (7, 32), which are at least partly separated from each other by weirs (6, 33). The pressure of the fluidizing gas introduced into the individual chambers through the distributor grates (7, 32), which are offset with respect to each other in vertical direction, substantially is the same. The delivery of the solids from the solids feed inlet 15 (37) to the solids discharge outlet (38) is promoted by the inclination of the fluidized-bed reactor (5, 30) with respect to the horizontal.

Abstract translation: 本发明涉及在流化床反应器（5,30）中热处理固体，特别是用于还原含有氧化铁的固体的方法和设备。 为了使固体流化，流化气体通过分配器格栅（7,32）引入流化床反应器（5,30）。 在固体进料管（37）和流化床反应器（5,30）的固体排放管（38）之间，固体通过具有分配器炉排（7,32）的多个室（8,34）， 它们通过堰（6,33）至少部分地彼此分离。 通过相对于彼此在垂直方向偏移的分配器格栅（7,32）引入到各个室中的流化气体的压力基本相同。 通过流化床反应器（5,30）相对于水平面的倾斜，促进固体从固体进料入口15（37）到固体排出口38的输送。
