Abstract

Experiments were performed to study the effect of the staging air−liquefied petroleum gas (LPG) mixing ratio and staging position on the exhaust gas emissions and carbon burnout of LPG and coal under co-firing conditions. An air−LPG mixture was supplied at three ratios (10%, 20%, and 30%) to four staging positions: upstream, midstream, downstream, and below the primary combustion zone. The results showed that the combustion was unstable when the staging position was downstream of the primary combustion zone, and the highest carbon monoxide (CO) emission with standard deviation (1500 and 730 ppm, respectively) were observed at a mixing ratio of 30%. Meanwhile, supplying the air−LPG mixture at a mixing ratio of 30% and upstream of the primary combustion zone resulted in the lowest nitric oxide (NO) emission of about 134 ppm. At a mixing ratio of 10%, the mixture was instantaneously burned out at the staging position on the inner wall of the furnace, which had a negative effect on the burnout performance. The air−LPG mixing ratios of 20% and 30% staged upstream of the primary combustion zone had a synergistic effect on the reduction of CO and NO emissions and the burnout performance.
