摘    要:借助TGA-MS技术研究了煤中的氯含量(高氯、中氯、低氯煤)对煤在燃烧时氯的析出特征的影响.MS的结果表明,HCl第一个析出峰是一个热作用过程,这部分氯是以离子状态存在于煤的内表面上,第二个HCl析出峰与煤的变质程度有关,而氯则是与煤的有机结构相连,当煤燃烧时,以HCl形式与CO2、SO2、H2O一起析出.第三个HCl析出峰是由于煤中无机氯化物而导致的.

关 键 词:TGA-MS  氯含量  煤的燃烧

Abstract:By using TGA-MS technique, the effect of C1 content on the evolution of HCl during combustion were evaluated. MS results show that three HCl peaks were observed during combustion. This indicates the existence of three mechanisms of chlorine binding and releasing. The first release peak is due to Cl - ion normally adsorbed on micropore walls. The second emission represents more tight bond with coal matrix. The third peak is a result of inorganic chlorides in the coal.
Keywords:TGA-MS  chlorine content  coal combustion
