Title:
WASTE TREATMENT METHOD
Document Type and Number:
Japanese Patent JP3964043
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for treating waste containing combustible and noncombustible materials.
SOLUTION: After waste is thermally decomposed to thermally decomposed char and thermally decomposed gas, the thermally decomposed char is gasified by oxygen or oxygen enriched air in the melting furnace 3 provided in the following thermal decomposition furnace 1 and the ash content is dissolved therein as well. A thermally decomposed gas reforming furnace 4 integrated to the melting furnace 3 is provided to the upper part of the melting furnace 3, and the gas gasified by the melting furnace 3 and the thermally decomposed gas are mixed together in the reforming furnace 4 so as to reform the tar content in the thermally decomposed gas and to generate a combustible gas.
