초록

경제 사회적인 여건의 변화에 의해 연료구입원이 다양해지고 있는 현 상황에서, 이들 다종의 석탄의 연소시 예상되는 문제점을 예측 및 해결하고자 석탄 시험 연소로에서의 종합적인 평가를 통한 산업용 및 발전용 미분탄의 연료특성평가를 시행하기 위해 시험연소 시스템을 구성하여 실제 국내 수입 이용되고 있는 인도네시아 Roto탄을 시험 적용하였다. 연소율은 98%이상이었으며, 선회도와 공기예열온도가 높을수록 안정한 화염을 생성하였다. 배가스 중 NO_x 농도는 선회도가 0.5-0.9 범위에 있을 때에 낮은 값을 보여 주었으며, 배가스중 산소 및 이산화탄소의 농도는 선회도의 변화에도 불구하고 거의 일정하였다.

Problems encountered in use of pulverized coal, in particular, have practical implications related to coal blending and up-grading of imported coals. Practically, significant problems are recognized in such aspects as control of the combustion process, fireside corrosion, ash and pollution. The methodology of predicting problems using pilot scale facility is less expensive, requires less coal and less time to execute, compared to the use of full scale facility. In this study, evaluation of Indonesian Roto coal was performed in a pilot scale coal combustion test facility. Burnout ratio of coal was higher then 98%, and increase of swirl number and preheat temperature of air made flame stabilize. NOx concentration in flue gas was lower in the range 0.5-0.9 of swirl number. Concentrations of oxygen and carbon dioxide in flue gas were constant in spite of variation of swirl number in this work.
