直燃式倾斜逆流回转窑以及其用途
摘要：
操作长直燃式倾斜逆流回转窑用于热处理材料的方法以及适配用于其的逆流回转窑，其中将待处理的材料在入口端(2)处引入窑中并且将经处理的材料在出口端(1)处从该窑中排出，其中主燃烧区(6)在该窑内在该窑的内部长度L内的1/4到1/3的距离上延伸，其中用富氧氧化剂发生补充燃烧的补充燃烧区(5)在该窑内在距该入口端(2)的该内部长度L内的最多1/4的距离上延伸，并且其中在位于该主燃烧区(6)与该补充燃烧区(8)之间的热交换区(7)内不发生燃烧。
摘要（英）：

Method of operating a long direct-fired inclined counterflow rotary kiln for the thermal treatment of material and counterflow rotary kiln adapted for same, whereby material to be treated is introduced into the kiln at the inlet end (2) and treated material is evacuated from the kiln at the outlet end (1), whereby a main combustion zone (6) extends inside the kiln over a distance of to 1/3 of the internal length Lint of the kiln, whereby a supplementary combustion zone (5) in which supplementary combustion takes place with an oxygen-rich oxidant extends inside the kiln over a distance from the inlet end (2) of at most of the internal length Lint, and whereby no combustion takes place in a heat exchange zone (7) located between the main combustion zone (6) and the supplementary combustion zone (8).
