摘　　要：富氧燃烧是一种能够综合控制燃煤污染物排放的新型洁净燃烧技术。针对O2/CO2气氛下石灰石煅烧分解特性进行了热力学分析和热重试验结果的动力学分析,将热力学分析结果与热重试验结果进行了对比,得出石灰石的起始分解温度随CO2分压比的增大而增高。Oxygen-enriched combustion technology is one of the new clean coal combustion technologies that can control pollutant emission.Thermodynamic analysis of limestone calcination under O_2/CO_2 atmosphere in fluidized bed condition was experimented.The results were accorded with thermodynamic analysis.The initial decomposing temperature of CaCO_3 increased with the increasing of CO_2 fractional pressure,but the increasing breadth was decreased.
