The first Water-cooled grates system, the most important key technology for Next generation stoker incinerator, was applied to an existing commercial waste incineration plant in Japan to demonstrate its operation performance Following results were confirmed for one-year incineration operation. (1)Surface temperature of the gates could be kept less than 70 degree-C and the long term stabilized incineration was confirmed by a sufficient cooling effect. (2)Abrasion loss of the gates was less than 0.5 mm for one-year operation and excellent durability was confirmed. (3)Stable operation with 8% O2 concentration in the flue gas at SCR outlet was confirmed with flue gas recirculation. (4)CO concentration in the flue gas could be kept at a low level sufficiently by mixing effect of flue gas recirculation as a part of secondary combustion air. (5)15% reduction of the flue gas emission was confirmed in case of flue gas recirculation.
