Abstract
내경 0.5 m, 높이 3.35 m의 유동층에서 제지 및 소화 하수슬러지의 연소특성을 연구하였다. 슬러지 연소 때 높이에 따른 온도변화를 살펴보면 층표면 근처에서 최대온도를 나타내었다. 함수량이 59.8%인 제지슬러지의 경우 보조연료 없이 연소가 가능하였으나, 함수량이 79.3%인 소화하수 슬러지의 경우는 보조연료를 사용하여야 연소가 가능하였다. 압력요동신호로부터 얻어진 평균압력과 표준편차로부터 유동층 운전의 안정성 여부를 판단할 수 있었고, 슬러지 투입량이 급격히 증가할 때 층표면 근처에서의 평균압력은 감소하는 경향을 보이는 반면, 표준편차는 증가하는 경향을 보였다. 일산화탄소의 배출량은 배가스 중의 산소농도의 증가에 따라 감소하는 경향을 보이나, NOx의 배출량은 증가하는 경향을 보였다.
Combustion characteristics both of paper and sewage sludges have been studied in a 0.5 mI.D×3.35 mH fluidized bed. The maximum temperature along the height was found and maintained near the surface of fluidized bed during the combustion. The paper sludge containing water about 59.8% of water could be burned without auxiliary fuel, while the auxiliary fuel was required to incinerate the sewage sludge, which containing about 79.3% of water. The stable operation status could be monitored by the mean pressure and the standard deviation of pressure fluctuation signal. The mean pressure near the surface of fluidized bed decreased with the increase of sludge feed rate. On the other hand, the standard deviation of pressure fluctuation increased with the increase of sludge feed rate. The emission of CO decreased with oxygen content in the flue gas, while that of NOx increased with the oxygen content.
