煤炭脱硫技术研究进展

Research progress of coal desulfurization

为提高煤炭的利用效率,实现煤炭的洁净利用,分析了煤炭燃前脱硫、燃中固硫和燃后脱硫的应用情况、脱硫效果和发展前景。结果表明:从成本最低考虑,燃前脱硫最经济,燃后脱硫成本最高。从我国国情分析,燃前脱硫无疑是最好的发展方向,燃中固硫、燃后脱硫作为辅助手段予以补充。因此实际应用中经常会把燃前、燃中、燃后多种方法结合起来,是未来脱硫技术的发展方向。

To realize clean and efficient use of coal,the application,effects and development of desulfurization before combustion,sulfur fixation and post combustion desulfurization were analyzed. The results showed that considering cost,desulfurization before combustion was economical,the cost of post combustion desulfurization was enormous. Based on the data and information collected,desulfurization before combustion was the best development direction,sulfur fixation and post combustion desulfurization as supplementary means to be added.Actual application often combined many kinds of desulfurization methods,which was the development direction of desulfurization technology.
