Ash melting technology has been introduced into municipal solid waste (MSW) treatment systems to satisfy the new regulations on Dioxins and the growing shortage of landfill site since 1990's in Japan. Authors have developed MSW gasification and melting furnace technology by combination of fluidized-bed MSW incinerator and swirling-flow ash melting furnace. In the melting furnace, minimum burner flame had been kept to ensure ignition and combustion of pyrolysis gas, even if the heating value and temperature of the gas varies with change of waste quality. Authors have developed a new on-line measuring system to monitor whether the pyrolysis gas can be ignited and combusted in the melting furnace. This system is installed in Aki Clean Center, and keeping burner flame is not necessary with this system. As the result, fuel consumption is reduced by 80% from that of that of conventional operation.
