摘要： PROBLEM TO BE SOLVED: To assure a stable power-generation quantity even when supply of waste to a gasifying furnace is stopped. SOLUTION: A gasifying fused power-generating system comprises a gasifying furnace 10 where a waste is gasified at a low air ratio to generate a combustible gas and char, a combustion furnace 16 where the combustible gas is combusted at high temperature, and a melting furnace 14 where the char is combusted and melted at high temperature. In a power-generating system like this, a char washed in a washing device 20 is dried with a drier 21, and then kept in a washed-char hopper 22. A thermo couple 24 is inserted in the gasifying furnace 10 with a controller 25 provided. The controller 25 supplies the combustion furnace 16 with the char of the washed-char hopper 22 when the inside of gasifying furnace 10 is judged to be in combustion state based on the detection signal from the thermo couple 24, for combustion in the combustion furnace 16. Thus, the inside of the combustion furnace 16 is kept at high temperature state for stable powergeneration quantity.

摘要： PROBLEM TO BE SOLVED: To lower the melting point of ash effectively even if it has a high melting point by always adding thereto an appropriate amount of a melting-point lowering agent. SOLUTION: In order to neutralize the chlorine element of the exhaust gas generated by incinerating refuse in an incinerator 1, slaked lime is thrown into exhaust gas from a hopper 5, and an amount of a melting-point lowering agent corresponding to that of slaked lime thrown into the exhaust gas is collected from the hopper 9 by a gas filter 4 and mixed with the ash in a mixer 11, and is melt in a melting furnace 13. For the melting-point lowering agent, SiO2 , 70% or more cullet (glass debris), silica-alumina compound, quartz sand and the like are used. The amount of the melting-point lowering agent added to the ash can be determined according to the adding amount of alkaline material based on the calibration curves of the adding amounts of the alkaline material and the melting-point lowering agent.

摘要： PROBLEM TO BE SOLVED: To provide a fly ash treating device which is compact and easy in maintenance and by which metallic elements contained in a waste gas from an ash melting furnace are separated and recovered with high efficiency and to provide a fly ash treating method. SOLUTION: This fly ash treating device is composed of a fly ash treating machine 2, a recovery device 4, a circulating blower 5, a temp. controller 8 and a fly ash collector 19. The fly ash collected by the collector 19 is charged into a heating chamber 2b through a hopper 2a and heated by a waste gas from an ash melting furnace 10 introduced into a duct 2c. The temp, of the heating chamber 2b is first controlled to 800-850 deg.C and kept at the temp. for several hours and further, the outlet temp. of the recovery device is controlled to 200 deg.C. Consequently, only Pb and Cd components are selectively vaporized and recovered. Subsequently, the fly ash left in the heating chamber is heated to 1000-1100 deg.C and kept at the temp. for several hours. At this time, the outlet temp. of the recovery device is maintained at 200 deg.C as well. Accordingly, Na, Cl and K components are selectively vaporized and recovered. Finally, a high-b. p. material such as Ca, Al, S remaining in the heating chamber is extracted from the bottom of the heating chamber.
