WASTE INCINERATOR

PURPOSE:To carry out high load operation and at the same time prevent atmospheric pollution by supplying and dispersing water from the furnace bottom bed section that is in combustion and evaporating and dispersing water and providing water gas reaction between red hot carbon and steam to control the temperature in the furnace and disturbing and stirring the combustion zone by means of secondary air. CONSTITUTION:Wastes are burned in a furnace 1, and pressurized water is supplied into the furnace 1 from a multihole device 5 constituted of a mulatto plate 3 and water jet nozzles 4 provided on the bottom bed face. The water is evaporated and dispersed by the combustion heat in the furnace. Then water gas reaction is developed between the steam and red hot carbon which is in the process of combustion. On the other hand secondary air for burning wastes and water gas is supplied into the furnace from a secondary air supply port 9 and it disturbs and stirs. With this arrangement the temperature in the furnace falls due to the endothermic action given by the water gas reaction. With this constitution the generation of nitrogen oxides sooth, etc., is suppressed and pollutants are reduced.
