摘要

METHOD AND APPARATUS FOR TREATING WASTE MATERIAL IN A COUNTER-CURRENT INCINERATOR The present invention is directed to method and apparatus for treating waste material in a counter-flow furnace wherein the material is introduced at one end thereof and the processed material is discharged from the other end, while the gases of combustion are caused to flow in counter-current direction with respect to the material being processed and are exhausted at the first end of the furnace, and wherein the furnace has a natural tendency to form zones of processing including sequentially from the first end of the furnace, a drying zone, a charring and volatile burning zone, a fixed carbon burning zone and an ash cooling zone, a method characterized by the step of adding an oxidant including water vapor to the fixed carbon burning zone. 1.
