高炉渣离心粒化余热回收工艺与结构设想

Preliminary Research on Recovery of Waste Heat from Centrifugal Granulation of Blast Furnace Slag

基于高炉渣显热特性,论文提出了一种通过离心粒化高炉渣、采用余热锅炉对高炉渣进行余热回收的干法高炉渣处理的工艺流程和结构设想。该新工艺具有结构简单、不消耗新水、不向大气排放有害气体等优势;有望实现余热锅炉蒸汽并入蒸汽管网,或用于发电,如实现设想,可产生可观的经济效益和良好的社会效益。

In view of the huge sensible heat characteristic of blast furnace slag, the paper proposed a new waste heat recovery process of blast furnace slag with dry processing in the waste heat boiler by granulating the slag u- tilizing the rotor. The technology process and the structures were proposed that there are so many advantages of sim- ple structures, free fresh water, free harmful gases into the atmosphere. It is suggested that steam generated by the waste heat boiler incorporate into the steam pipe networks or the generate electricity. A great improvement in the eco- nomic and social benefits is expected by using the new technology.
