Abstract
The present invention relates to a method for treating combustibles by slagging combustion, such as municipal wastes, plastic wastes, sewage sludges, or automobile wastes. Combustibles and oxygen-containing gas are supplied to a slagging combustion furnace (,), and the combustibles are partially oxidized under a reducing atmosphere in a primary combustion chamber (,) to obtain combustible gas and convert ash content in the combustibles into molten slag which is discharged from a slag separation chamber (,), and then the combustible gas is completely combusted in a secondary combustion chamber (,) by supplying oxygen-containing gas.
