摘  要:采用正交试验法,研究了4种因素对煤高温燃烧固硫效率的影响,发现原煤硫分影响最显著,钙硫比影响十分显著,石灰石与电石渣的成分配比影响较显著,而钢渣以及各因子间的交互作用影响甚微.通过方差统计得到一组最佳实验条件:原煤硫分为4%,钙硫比为2,石灰石与电石渣的质量配比为60∶40,钢渣添加量为0.6%,在炉温1200℃下得到52%的燃煤固硫率.Four influence factors on sulfation reactions of industrial wastes in coal combustion were studied by a series of orthogonal experiments. It is found that the initial sulfur content in coal ( St,ad) is the most prominent influence factor and the next is the molar ratio of calcium to sulfur (Ca/S). The weight ratio of limestone to carbide lime in the sorbent (L/C) takes the third place, while the addition percentage of steel residue (Par) and the interactions of different factors have small influences. The best experimental condition is as the flowing: ω (St,ad) = 4%, n (Ca) /n (S) =2, n (L) /n (C) =60:40, ω (Pst) =0.6%. The highest sulfur retention efficiency of 52% was obtained in coal combustion at the furnace temperature of 1 200℃.
