A study on small-scale gasification and power generation from municipal solid wastes and biomass fuels

Abstract

We have been developing small-scale gasification and power generation systems utilizing solid wastes. Based on the R & D achievements, a local town in Japan has built a 1 t/h scale slagging MSW (Municipal Solid Waste) gasifier combined with 900 kW dual-fueled diesel engines. This town will receives meat-and-bone meals to mix with MSW and feeds them into the plant as biomass fuels. It is expected that this plant will utilize 0.5 t/h MSW and 0.5 t/h meat- and-bone meals as fuels to generate 900 kW electric power. This paper describes the outline of this plant and discusses about effects of fuel composition and gasification air ratio on gasification performance as well as power generation results.
