Abstract
Energy for power generation is almost fossil fuel and atomic energy in Japan. The new energy that is natural energy such as solar energy, wind force, geothermal energy and hydrauric power and biomass should be considered as alternative energy to reduce CO_2 emission. Energy from waste is discussed as one of new energy. Ministry of Economy, Trade and Industry has set up the aim that the power generation from waste in 2010 becomes five times of 1999. One the other hand the new technology for waste treatment is adopted in recent years. The system can produce char that has high calorific value and similar characteristics to pulverized coal. This paper introduces the combined system of pyrolysis system and coal power generation plant. If the char produced in waste treatment plant is utilized in power plant as fuel, the power generation will become 1.7 times of the pyrolysis and melting plant of waste treatment.
