Abstract

In this study, we conducted a study on characteristics of exhaust gas emissions from boiler when water-bunker oil mixed by homogenizer was burned in boiler. The results showed that NOx concentration and CO concentration of the homogenized bunker oil was decreased by 19% and 54% compared to pure bunker oil pretreatment was not being performed. And, in the case of water-bunker A oil, the NOx concentration was decreased with increasing water mixing ratio in bunker A oil. In particular, the NOx concentration in exhaust gas of 20 %water-80 %bunker A oil decrease by 45 % compared with pure bunker-A. However, the CO concentration in exhaust gas of 20 %water-80 %bunker A oil shows irregular changes. This means that the mixing of water more than a certain amount can cause a decrease in combustion performance. From this result, it can be found that critical mixing ratio of water in bunker A oil for normal combustion is 15% in this study. Deposition amount of soot that is collected in the vicinity of the chimney was decreased with increasing water mixing ratio.

본 연구에서는 균질기에 의해 혼합된 물과 벙커-A를 보일러로 연소하였을 때의 배기 배출물 특성에 대해 연구를 수행하였다. 그 결과로 균질기로 균질화 된 벙커-A의 경우, 순수 벙커-A에 비해 NOx 농도는 19 %, CO 농도는 54 % 감소를 나타냈다. 물-벙커A의 경우 물 혼합 비율이 증가할수록 NOx 농도분포가 낮아지는 것을 확인할 수 있었다. 특히, 20 %물-80 %벙커-A의 경우 순수한 벙커-A 보다 배기가스 내 NOx 농도가 45 %까지 감소하였다. 그러나 20 %물-80 %벙커-A의 경우, CO농도 분포는 불규칙한 변화를 나타냈다. 이것은 일정량 이상의 물 혼합은 보일러의 연소 성능 저하 원인이 될 수 있다는 것을 의미한다. 이 결과로부터 본 연구에서 보일러의 정상 연소를 위한벙커A유 내 물의 한계 혼합율은 15 % 인 것을 알 수 있었다. 연돌 부근에서 채취한 매연 부착양은 물의 혼합율이 증가할수록 감소하였다.
