PILOT-PLANT FOR NOX, SO2 AND HCL REMOVAL FROM FLUE-GAS OF MUNICIPAL WASTE INCINERATOR BY ELECTRON-BEAM IRRADIATION

According to the basic research performed using a small size reactor a t TRCRE of JAERI, the electron beam irradiation process was proved to be very effective for NO(x), SO2 and HCl removals from flue-gas of mun icipal waste incinerators. Based on this result, a pilot-plant was con structed for the demonstration of NO(x), SO2 and HCl removal performan ce using electron accelerator of maximum energy 0.95 MeV and maximum p ower 15kW. The pilot-plant was constructed at Matsudo City Waste Dispo sal Center. The flue-gas of 1,000 Nm3/hr is guided from the waste inci nerator flue-gas line of 30,000 Nm3/hr to the pilot-plant to be proces sed by spraying Ca (OH)2 Slurry or powder and irradiation with high-en ergy electron beam of the accelerator. NO(x), SO2 and HCl are removed simultaneously from the flue-gas by the enhanced reaction with Ca (OH) 2 under irradiation.
