摘　　要：为了获得高效实用的固硫剂,该文以生产用煤作为试验用煤,采用正交试验法和热重分析法,研究了固硫剂种类、Ca/S摩尔比、燃烧温度、煤粉粒度以及预处理时间等因素对固硫效率的影响;在单一钙基固硫剂的试验基础上,又考察了固硫添加剂种类、加入量以及预处理时间等因素对固硫率的影响;综上试验结果,确定了固硫剂的成分为Ca O、Na2CO3、Cu Cl2·H2O,其配比为86%:7%:7%。固硫的一体化试验结果表明,在煤粉中加入2.0%的助燃固硫剂,可以使煤粉着火点降低39℃,燃烧率提高了12.96%,固硫率达61.32%。In order to obtain efficient and practical sulfur fixation,the paper choose the coal used in production in the experiment,sulfur fixation sorbent types,Ca/S molar ratio,combustion temperature, particle size of coal and pretreatment time on the sulfur fixation efficiency; based on the single test on calcium-based sulfur retention agent, and investigated the type of sulfur fixation additives,adding volume and pretreatment time on the desulfurization rate;comprehensive test results on the three groups to determine the composition of sulfur fixation for the CaO,Na2CO3,CuCl2·H2O,the ratio is 86%：7%：7%.The integration of sulfur combustion test results showed that the addition of 2.0% sulfur fixation into coal can lower the ignition point of 39 ℃,improve combustion ratio by 12.96%,improve the sulfur fixation efficiency to 61.32%.
