Abstract (en)
[origin: EP0636847A1] The outlet end (9) of a rotary drum furnace (8) for the heat treatment of free-flowing materials, in particular bulk materials, is essentially subjected to stresses which occur simultaneously and in different proportions. Various embodiments of the outlet end (9) of rotary drum furnaces (8) are therefore known from practice, where it has proved to be particularly successful to design the outlet end (9) in the form of a double casing, its closure being formed by outlet-protection segmental parts (11, 12, 13). In order to meet increased demands, in particular with regard to a higher thermal loading capacity, it is proposed according to the invention to construct the outlet-protection segmental parts (11, 12, 13) in several pieces and to design the segmental parts in such a way that they can be releasably connected to one another free of stress in the form of push-in connections so that a largely gastight and dustproof closure of the double casing is achieved. <IMAGE>
