Abstract
In viewpoints of environmental and resource conservation, it is desirable to utilize fly ash generated from domestic coal power stations as light constructive material. Furthermore, the demand of light constructive materials has been increased as many building tend to become highly multistory buildings. In demonstration of converting fly ash to light constructive materials, the Dwight-Lloyd kiln of which the operation is relatively easy and the reliability very high has been informed to be only commercialized plant over the world. In this review, Dwight-Lloyd kiln plant operated at Oomura coal power station in Japan is explained. Circular grate kiln, Shaft kiln, Rotary kiln plants that are under developed is also introduced.
