Abstract
A waste gasification system, which is equipped with pyrolysis rotary kiln and gas cracker, is reported. After building a pilot plant first, it advanced to construction of a demonstration plant to a commercial plant, then it became possible to realize processing stabilized as a result. Moreover, much plant data was acquired. In an incinerator, after burning waste, heat recovery is performed, combustion gas is purified after that. On the other hand, in a gasification system, energy use is carried out, after purifying the gasified gas. Since gasification is performed in a hot reduction atmosphere, a possibility that generating of high temperature corrosion and generation of dioxins are controlled is strong. Furthermore, although the amount of calories per unit capacity of the generated clean fuel gas is low, since combining with an efficient power generation system etc. is possible, the improvement in efficiency of generating electricity from waste materials is expected by using this system.
