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.
