Abstract
A waste incineration machine capable of rendering a waste gas occurring during the combustion of waste smokeless and odorless. A heat insulating wall to which a first far infrared ray radiator is fixed is provided so as to surround a combustion furnace and a combustion chamber, and a heat exchanger so as to surround the heat insulating wall. An inner flue is formed between the heat insulating wall and combustion furnace, and an outer flue serving as a waste gas convection chamber between the heat insulating wall and heat exchanger. An upper part of a communication portion between the inner and outer flues is covered with a heat insulating member constituting a second far infrared ray radiator so as to subject the waste gas to secondary heating using far infrared rays, and thereby to render the waste gas smokeless and odorless. Preferably, the heat insulating wall is formed into a substantially cylindrical shape, and the heat exchanger into a rectangular box-shape open at the top and the bottom, whereby the volume of the outer flue is increased to thereby lengthen the time for circulating the waste gas by convection.
