A tuyere structure and a combustible dust blowing method in which the quantity of coke consumed can be reduced by combusting combustible dust blown in from the tuyere of a waste fusion furnace completely in front of the tuyere. In the waste fusion furnace for drying, thermally decomposing, combusting, and fusing waste to treat the waste by inputting waste into the furnace together with coke and limestone, supplying air or oxygen-rich air from the tuyere provided in the furnace, the tuyere (20) has a triple tube structure of an inner tube (22) for supplying combustible dust and air or oxygen-rich air, an intermediate tube (23) for supplying fuel for firing the combustible dust, and an outer tube (24) for supplying oxygen for combusting the firing fuel. The respective tubes are interconnected at the forward end part thereof. ® KIPO & WIPO 2007
