Abstract

PURPOSE:To permit the supply of air necessary for materials to be incinerated after igniting them surely by a method wherein an inner wall plate, on which a multitude of venting holes are bored, is mounted at the inside of side walls of an incinerating chamber with a gap for venting, which is provided between the side walls and communicating with an empty chamber. CONSTITUTION:An inner wall plate 15, on which a multitude of venting holes 14 are bored in the circumferential direction thereof, is mounted detachably at the inside of the side walls 3 of a primary incinerating chamber 2 while an empty chamber 17, communicating with an ash take-out port 16, is formed at the bottom of the incinerator. The inner wall plate 15 is formed integrally by integrating bent pieces 19, formed by bending both ends of neighboring pieces in the circumferential direction of the inner wall plates 15. The lower ends of the bent parts are supported by a supporting metals fixed to the side walls 3 of the primary incinerating chamber 2 through welding and the like. A gap 21 for venting is formed between the side walls 3 by the abutment of the tip ends of the bent pieces 19 against the supporting metals. According to this method, combustion air can be supplied surely to the matters to be incinerated through the gap between the inner wall plates and the side walls.
