The municipal solid waste (MSW) gasification and melting system has been developed using a 20t/d demonstration plant built in SHI Niihama Works. This system is comprised of a gasifier of circulated fluidized bed type and a melting furnace of kiln type. In the gasifier, MSW is converted to combustible gas and char at a gasification temperature of 750-900℃. In the melting furnace, a part of combustible gas and char is burned at a temperature of over 1200℃. Then the ash in char is melted. Surplus gas is used as fuel at a MSW dryer and a boiler. The demonstration test has been conducted for a period of 1.5 years (including continuous 30days) since November 1999. During this operation, this plant has processed 2,224tons of MSW. Operation results indicate that dioxins emission in flue gas (stack inlet) is below 0.05ng/m3N and safely and useful slag is produced in this plant
