ABSTRACT:
A waste combustion system includes a porous apparatus for supplying and spraying a suitable amount of water from at least the bottom floor surface and/or a lower inner surface of the furnace. Water vapor generated from the water is dispersed, and it undergoes the water gas reactions with red-hot carbon during a combustion process. The water gas reactions serve as the endothermic reactions which control the temperature within the furnace into suitable temperatures. In addition, while secondary air from a secondary air introducing apparatus is being supplied into the combustion chamber of the furnace, the burning zone of the waste is subjected to violent agitation and stirring actions so as to limit the generation of such substances as nitrogen oxides and soot, hence, to reduce the proportion of pollutants contained in the exhaust gases.
