摘　　要：干排电石渣在水泥工业预热器中的热分解是在烟气条件下进行的,为了掌握干排电石渣在预热器系统中的化学反应过程,采用可调节温度的气氛炉作为实验装置。通过调节气氛炉内的CO2浓度、温度和反应时间,分析反应后的产物得到：350-650℃低温段内,存在CaCO3的合成;在800℃下,CO2气氛条件下电石渣分解得到的产物为CaO。Heat decomposition of carbide sludge on acetylene by dry process is under smoke in the preheater of cement industry,the CO2 atmosphere furnace was adopted in control of the reaction process of carbide sludge in preheater system.With adjusting the temperature,time and the concentration of CO2,it was received that calcium carbonate synthesis in 350～650 ℃ which was not existed in the temperature of 800 ℃ at the CO2 atmosphere.
