Japanese RDF-fired power generation system and fundamental research on RDF combustion

摘要

Power generation from refuse derived fuel (RDF) is one of the new technologies for municipal solid waste (MSW) management. This technology is strongly attracting the attention of the Japanese government. The results of a feasibility study of thissystem in Japan is presented.To develop this highly efficient RDF-fired CFB generating process, combustibility and dechlorination characteristics of RDF were investigated by both the thermo-balance technique and combustion tests with an electric furnace.RDF combustion tests by an bench scale CFBC were carried out and then the following experimental results were obtained.1) RDF can be combusted almost completely even in small scale CFBC.2) RCl and N{sub}2O emissions are quite low at any conditions.3) NOx emissions are a little higher in single stage combustion, however they are reduced at 50% air bias ratio.Some of the results can be explained by a RDF combustion model.
