摘　　要：对浙江省8种石煤的硫析出特性及加入钙基固硫剂以后的影响进行了研究，得出了石煤的硫析出特性与其他煤种有相似之处：即有2个明显的硫析出峰值；燃烧温度对硫析出有很大的影响，温度升高，硫析出量增加，析出时间提前；在1200℃时已经有超过95％以上的硫分解析出．同时得出钙基固硫剂对于石煤的硫分析出有很明显的抑止作用，方解石和石灰石脱硫率为40％～50％．纳米碳酸钙达到70％．Studied sulfure releasing characteristic of eight kinds of stone coal, which were gotten Zhejiang Province, and the effect after adding CaCO3 , the results show that Sulfwre releasing characteristic is similitude with other coal. They have two peak values of SO2 releasing. Burning temperature has a tremendous influence on sulfur release. When temperature rise, it has more SO2 released and SO2 released earlier. When the temperature is 1 200 ℃ the released sulfur is over 95%. Some＇calcic additives have remarkable effect on restraining sulfur releasing. Desulfurizing rate of calcite and limestone are 40% - 50% and nano - CaCO3 is 70%.
