METHOD AND APPARATUS FOR TREATING WASTE

摘要

PROBLEM TO BE SOLVED: To provide a method for treating waste which can solve the problem of corrosion of a boiler tube and recover heat efficiently when heat is recovered from a waste combustion gas by a boiler and an apparatus for the method. SOLUTION: Waste is burned incompletely or oxidized partially in a partially oxidizing combustion furnace 1 to produce a combustible gas of -30 to -2% concentration based on oxygen at the outlet of the furnace, the gas is introduced into a dust collector 2 at 500-800 deg.C to reduce a dust concentration to 0.1 g/m3 or bellow, and the dedusted combustible gas is burned at a high temperatures in a combustion furnace 3.
