摘要
在分析我国煤炭资源状况、煤中硫的赋存状态和燃煤引起的SO2污染状况的基础上,探讨了国内外控制SO2排放的研究现状,研究了燃烧前、燃烧中和燃烧后三大类脱硫方法的可行性与适用范围。研究认为,对洗选脱硫要先对煤中硫的赋存状态进行研究,否则效率难以得到保证;固硫剂脱硫比较适合我国国情,但脱硫效率有待提高。固硫剂脱硫和洗选脱硫可结合使用,以提高脱硫率。
Based on analyzing coal resources in China, occurrence state of sulfur and SO2 pollution, the status of controlling SO2 emission at home and abroad were studied. The feasibility and applicability of three kinds of desulfuration methods was discussed. Tiffs paper suggested that occurrence state of sulfur should be study for coal washing or removal efficiency of SO2 couldn＇t be ensured. Desulfurafion with fixed - sulfur sorbents and addifives was suitable to China, but the removal efficiency should be improved. The combination of coal washing and fixed - sulfur sorbents could achieve high removal efficiency. The result could supply reference for coal plant.
