Abstract

This research was performed to evaluate incineration facilities with different scale and type using performance index. Incineration facilities of 28 units, which occupying about 15% of 184 units in nationwide, were selected for questionnaire survey. The facilities were classified in scale with large(${\geq}100t/d$), middle(50~<100 t/d), small(<50 t/d) ones, and in type with stoker, pyrolysis, fluidized bed. Performance index was composed of technological, economical, and environmental items, which have 6, 10, and 30 kinds of questions, respectively. As a result of scale evaluation, large scale facility has higher score than small one in all technological, economical, and environmental items. In overall evaluation of the facilities with different type, stoker incinerator has higher score of 65.3 than 59.0 of fludized bed and 58.3 of pyrolysis. It was shown that there was significant difference in economical evaluation field, in all technological, economical, and environmental items.

본 연구는 소각시설을 규모별, 유형별로 평가하기 위하여 이행지표를 설정한 후 설문조사를 실시하였다. 설문대상 수는 2012년 기준 전국 184개 중 약 15%인 28개를 선정하였다. 규모별로 대규모(${\geq}100t/d$), 중규모(50~<100 t/d), 소규모(<50 t/d)로 나누고, 유형별로는 스토커, 열분해, 유동층으로 분류하였다. 이행지표는 기술성, 경제성, 환경성으로 대별한 후 각각 6개, 10개, 30개의 세부항목을 설정하고 5등급으로 나누어 점수를 부과하였다. 평가결과 소각시설 규모별로는 기술성, 경제성, 환경성 평가에서 모두 대규모 시설이 소규모 시설 보다 높은 점수를 받았으며, 종합점수에서도 동일한 경향을 나타내어 소각시설의 규모가 증가할수록 더 높은 평가 점수를 받는 것을 알 수 있었다. 소각시설 유형별로는 기술성, 경제성, 환경성을 종합 평가한 결과에서 스토커식(65.3점)이 유동상(59.0점) 및 열분해(58.3점) 보다 우수한 평가결과를 나타내었다. 특히 소각시설 평가시 기술성, 경제성, 환경성 중 경제성에서 뚜렷한 차이를 나타내었다.
