Abstract

도시 폐기물의 효율적인 처리방법중의 하나인 소각은 폐기물을 감량화시키고 폐열도 이용할 수 있어 점차 증가하고 있다. 본 연구는 3차원 수치모델을 개발하여 대형 도시폐기물 소각로인 상무소각로에 연소특성과 최적의 운전조건을 파악하기 위하여 적용하였다. 아울러 개발된 3차원 수치모델을 실제 운전시와 동일한 조건으로 수치해석하여 얻어진 온도와 실측치 온도를 비교하여 모델의 적용성을 검증하였다. 본 모델을 적용하여 상무소각로의 소각시에 로내 연소특성을 파악한 결과 1차 공기가 충분하지 못하여 후연소영역에 불완전 연소생성물의 발생이 높지만 주화염대에서 2차 연소되어 불완전 연소생성물이 낮게 배출되고 연소효율이 좋은 특성을 가진다.

The interest of incineration, which is one of the effective methods for municipal waste disposal, has gradually increased because the incineration could reduce the volume and weight of the waste, and produce useful energy from the waste. This study has developed the 3-dimensional numerical model, and applied for the investigation of combustion characteristics and optimized operating conditions in MSW incinerator in Gwangju. The model developed in this study has been verified through the comparison between the predicted and the measured temperature in combustion chamber which is operating. By predictive results, the Sangmoo incinerator has a good characteristics of combustion efficiency and a low emission by the second burning in the main flame zone, even though after burning zone produces incomplete products by which primary air is introduced not enough.
