Abstract
Waste material containing combustible waste substances and incombustible waste substances along with carbonic massive combustibles are feed for passage in a furnace in the form of packed layers. Lower stage tuyeres feed burning support gas in the burning and melting zone of the furnace. Upper stage tuyeres feed burning support gas in the heat decomposing zone of the furnace. Total oxygen fed by the upper and lower tuyeres is 130 to 600 Nm,per one ton of waste. The ratio of the quantity of oxygen fed from the upper stage tuyeres to the total quantity of oxygen fed from both the upper and lower stage tuyeres is 0.2 to 0.8. Oxygen fed from the lower stage tuyeres is at least 0.8 times the theoretical oxygen required for burning the carbonic massive combustibles.
