Abstract

According to the basic research performed using a small size reactor at TRCRE of JAERI, the electron beam irradiation process was proved to be very effective for NOx, SO2 and HC⪋ removals from flue-gas of municipal waste incinerators. Based on this result, a pilot-plant was constructed for the demonstration of NOx, SO2 and HC⪋ removal performance using electron accelerator of maximum energy 0.95 MeV and maximum power 15kW.

The pilot-plant was constructed at Matsudo City waste Disposal Center. The flue-gas of 1,000 Nm3/hr is guided from the waste incinerator flue-gas line of 30,000Nm3/hr to the pilot-plant to be processed by spraying Ca(OH)2 slurry or powder and irradiation with high-energy electron beam of the accelerator. NOx, SO2 and HC⪋ are removed simultaneously from the flue-gas by the enhanced reaction with Ca (OH)2 under irradiation.

A brief explanation of the pilot-plant and preliminary results of the experiments are introduced in this paper.
