Refuse Derived Fuel (RDF) Fired Power Plant

Abstract

In Japan, municipal waste amounts to 50 million tons a year and its incineration ratio at present is approximately 74%. However, the generation of electricity from firing municipal waste is limited because of its characteristics ; namely municipal waste vary in shape and are apt to rot or decompose and emit odor. Therefore, they are not suitable for transportation or storage.
Refuse derived fuel (RDF) for municipal waste is the pelletizing one made from municipal waste. Hard and dry RDF with calcium compounds can be stored for a long time, handled and transported easily.
Moreover, high-efficiency power generation is possible by gathering RDF manufactured from local communities and applying a circulating fluidized bed boiler with external circulation system for its combustion.
