摘　　要：以普通烟煤(长焰煤)为原料煤,考察了固硫剂的引入以及固硫添加剂的添加对烟煤固硫率的影响,并通过TG-MS初步分析了复合固硫剂的固硫机理。进一步压制得到了工业洁净型煤,并在0.5 t的工业链条锅炉上进行了试烧,进一步获得了型煤在实际燃烧过程中的污染物排放数据。研究结果表明,随着钙硫比的增大(1.5~2.5),钙基固硫剂固硫率逐渐提高,以SiO_2作为添加剂时,复合固硫剂固硫率效果较好,达到了69.1%。实际试烧效果也表明,加入添加剂后,型煤燃烧固硫减排效果明显,链条炉上SO_2减排量达到33.3%。Using the long-flame coal as the raw coal,the introduction of sulfur retention sorbent and the effect of the addition of sulfur retention sorbent on the sulfur retention rate were investigated. And the sulfur retention mechanism of the compound sulfur retention sorbent was preliminarily analyzed by TG-MS. After that,the industrial clean briquette was further prepared,and the test was carried out on 0. 5 tons industrial chain boiler,and the data of the pollutant discharge in the actual combustion process of the briquette was further obtained. The results show that with the increase of the ratio of Ca/S（1. 5 - 2. 5）,the sulfur retention rate of calcium-based sulfur retention sorbent is increased gradually. When SiO2 is used as additive,the effect of the sulfur fixation rate of the compound sulfur retention sorbent reaches 69. 1%. The actual burning test results also show that after adding additives,the emission reduction of briquettes combustion and sulfur retention is obvious,and the SO2 reduction on chain furnace reaches 33. 3%.
