<p><P>PROBLEM TO BE SOLVED: To provide a waste melting disposal method preventing impurity incorporation into slag to avoid pop-out of concrete product. <P>SOLUTION: In the waste melting disposal method where waste is charged in a drying shaft part 1 which dries the waste from the top of drying shaft part 1 to form waste packed bed, while drying the waste by passing the gas generated both in a fire grate part 2 which generates a thermal decomposition residual substance and in a thermal decomposition residual substance melting part 3 which melts thermal decomposition residual substance by making coke as a heat source through the waste packed bed formed, the gas passing through the waste packed bed is discharged from the top of drying shaft part 1, then the waste dried in the drying shaft part 1 is decomposed thermally in the fire grate part 2 to generate a thermal decomposition residual substance 19, and finally the thermal decomposition residual substance 19 that has been generated is continuously dropped from the fire grate part 2 to supply into the thermal decomposition residual substance melting part 3 for melting, injection of limestone is stopped in tapping. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
