WASTES INCINERATION DISPOSAL METHOD

Title:

WASTES INCINERATION DISPOSAL METHOD

Document Type and Number:

WIPO Patent Application WO/2000/017289

Kind Code:

A1

Abstract:

An incineration disposal method for wastes for preventing PCDDs emission and shortening a disposal cycle, wherein wastes are dry-distilled in a gasification furnace and a combustible gas generated is burned in a combustion furnace. Oxygen is supplied to the combustion furnace according to the volume of the combustible gas, while an oxygen volume supplied to the gasification furnace is controlled according to a change in combustion gas combustion temperature so as to regulate the production volume of the combustible gas to keep a combustion furnace temperature at approximately constant one higher than a preset temperature. When a gasification furnace temperature lowers from a maximum temperature to below a PCDDs production temperature after a combustion furnace temperature falls to below the approximately constant temperature, burned residues are immediately taken out from the gasification furnace. Alternatively, while a gasification furnace temperature is falling from the maximum temperature, burned residues are housed in a fusion furnace connected with the gasification furnace. Thereafter, new wastes are charged into the gasification furnace and ignited. The burned residues are heated in the fusion furnace and molten matter is placed into water for quenching to thereby form granulated solid matter.
