<P>PROBLEM TO BE SOLVED: To provide a method and a system for waste melting disposal which prevent clinker generation of a fire grate part of the same system. <P>SOLUTION: In the waste melting disposal method where the gas generated both in the fire grate part 2 generating thermal decomposition residual substance and in the thermal decomposition residual substance melting part 3 of the melting furnace 6 melting the thermal decomposition residual substance by making coke as heat source is passed through the waste packed bed formed by charging the waste from the top of drying shaft part 1 for drying to dry up the waste, the gas passed through the waste packed bed is emitted from the exhaust discharge port 9 of the drying shaft part 1 to be processed for detoxication with an exhaust treatment system to be discharged through the exhaust flue 24, whereas the waste dried in the drying shaft part 1 is decomposed thermally in the fire grate part 2 to generate the thermal decomposition residual substance 19, which is continuously dropped from the fire grate part 2 to be supplied to the thermal decomposition residual substance melting part 3 for melting, the exhaust is brought out from the exhaust flue 24 to blow into below the fire grate part 2 for controlling temperature of the upper part of fire grate part less than a clinker generation temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
