<P>PROBLEM TO BE SOLVED: To efficiently and surely completely burn waste through drying (low temperature)→decomposition (middle temperature)→combustion (high temperature), without discharging toxic substances such as dioxin. <P>SOLUTION: A first combustion furnace 1 provided with a feed port 11 and a second combustion furnace 41 are connected by a first flue 70 in the lateral direction and the second combustion furnace 41 and an exhaust gas cleaning tank 55 are connected by a second flue 80, thereby combustion device 90 is formed. On the sidewall of the first combustion furnace 1, many nozzles 24 are arranged in the lateral direction to form a nozzle group 25 consisting of nozzle sub-groups 25a, 25b and 25c in three vertical stages, and the distal end of each of the many nozzles 24 is turned to the inside of the furnace as a high pressure air discharge port. A flame port 15 of a burner is disposed near an opening 13 toward the first flue 70 at the upper end part of the first combustion furnace 1. The respective nozzle sub-groups 25a, 25b and 25c are formed so that the pressure on the side near the flame port 15 becomes relatively high and pressures on the other sides become relatively low. To the first combustion furnace 1, a high pressure air injecting projection port 22 capable of discharging high pressure air obliquely downwards is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
