摘要 在管式炉上研究了醋酸调制白云石产物、醋酸钙、丙酸钙等有机钙作用下龙口褐煤燃烧时SO2、NO的析出特性,并在热分析系统上考察了相应的燃烧特性。合适的工况条件下有机钙能有效抑制SO2、NO的析出。在973~1273 K下,有机钙均能有效抑制SO2的析出,而当温度继续升高,除醋酸钙外,其他有机钙抑制效果下降。在973~1 173 K时,有机钙促进了NO的析出,而当温度高于1 173 K时,醋酸钙和丙酸钙的抑制效果明显。随着钙硫比的增加,有机钙对SO2、NO抑制效果普遍增强,而醋酸调制白云石产物在钙硫比为2.0~2.5时却促进NO的析出。当钙硫比为2.0时,褐煤着火性能明显提高,着火点降低10~33 K,但其燃尽时间稍有延长。 The effect of the calcium based organic compounds of the modified dolomite by acetate(MDA),calcium acetate(CA) and calcium propionate(CP) on the release of sulfur dioxide(SO2) and nitric oxide(NO) during LK-lignite combustion has been investigated on a horizontal tuber furnace.And also,the combustion characteristics of them have been studied in a thermogravimetric analyzer.Calcium based organic compound can suppress the release of SO2 and NO under the suitable conditions effectively.In the temperature range of 973~1 273 K,the calcium based organic can inhibit the release of SO2.But when the temperature grows higher,the inhibition effect of the calcium based organic reduces except CA.In the lower temperature range of 973~1 173 K,the calcium based organic promotes the release of NO,but when the temperature is higher than 1 173 K,CA and CP show the inhibition of NO obviously.The inhibition effect of SO2 and NO by calcium based organic generally increases with the increase of the mole ratio of calcium to sulfur(Ca/S).But when the Ca/S is between 2.0 and 2.5,MDA promotes the release of NO.With adding the calcium based organic to LK-lignite,when the Ca/S is 2.0,the ignition performance of LK-lignite improves,the ignition reduces 10~33 K,but its burn time is slightly lengthened.
