发明名称 Method of thermal treatment of fine-grained material and apparatus for thermal treatment of fine-grained material
摘要 A method and apparatus for heat treatment of fine-grained material. In order to reduce the nitrogen oxide content of the exhaust gas from the combustion zone, a region of the calcination zone is operated under reducing conditions and ammonia-containing additives are introduced into the calcination zone. In this case, at least the predominant proportion of the ammonia-containing additives is only added in a region of the calcination zone in which the secondary combustion of the combustion products which are formed in the section operated under reducing conditions but are not completely reacted out is largely concluded.
