GRATE-TYPE WASTE INCINERATOR AND METHOD FOR INCINERATING WASTE

WIPO Patent Application WO/2013/133290

A1

Provided is a grate-type waste incinerator that is capable of reducing the amount of hazardous substance generation, and performing combustion of waste with ease using a low air ratio, and a method for incinerating waste. An incinerator (1) includes a combustion chamber (2) that combusts waste (W) while the waste moves on a grate (5); a primary gas blowing unit (FABU) that blows a primary combustion gas (A) from below the grate into the combustion chamber; and a hot gas blowing unit (HGBU) that has a plurality of hot gas blowing ports (13) which blow hot gas (B) down from an upper position one to three meters away from the grate in the combustion chamber toward a predetermined site between a waste combustion initiation area and a main combustion area in the combustion chamber. The hot gas that is blown in inhibits an upward flow of the combustion gas that contains a flammable gas which is generated from the waste, and induces stagnation or circulation of the hot gas or the combustion gas for the waste on the grate to provide a stable planar combustion area for the waste.
