Abstract

In this study, operation data from an actual plant in M city were analyzed to evaluate effects of water supply into sewage sludge on the co-incineration of municipal solid waste (MSW) and sewage sludge. Design capacity of the stoker incinerator is 50 m3/day. Maximum portion of sewage sludge in the total waste input was 20%. According to this research, moisture content increase up to 85% of sewage sludge could be possible by water supply on MSW input to the incinerator. Therefore, stable operation of incinerator could be achieved. As water was added into sewage sludge up to 85%, input quantity of sewage sludge to frequency (Hz) was similar to theoretical input. Also, it is concluded that stable management of incinerator without leachate combustion and damages of refractory bricks and castable could be achieved by the reduction of low heating value.

본 연구에서는 하수슬러지 처분대안으로서 하수슬러지를 생활폐기물과 혼합소각시 안정적 소각로 운전을 위한 하수슬러지의 정량공급방안에 대하여 실증플랜트를 중심으로 고찰하고자 하수슬러지의 원활한 공급방안으로 이송배관에 수분을 공급 하는 경우와 공급하지 않는 경우, 공급 모노펌프의 인버터 조절(Hz)에 따라 하수슬러지 정량공급 여부를 측정하고자 한다. 실험결과, 함수율 85%에서 인버터 조절(Hz)에 따른 이론적 슬러지 공급량과 일치하는 것으로 나타나 소각시설의 안정적 운영이 가능할 것으로 판단된다.
