摘要

磷酸酯抗燃油的劣化直接影响发电机组运行的安全性及经济性。本文结合烃类自由基氧化的链锁反应机理及某机组抗燃油氧化案例分析

以及在不同温度下对磷酸酯抗燃油的开口杯老化试验，研究了影响磷酸酯抗燃油热氧化的因素。结果表明:温度在60 ℃以内时

油质无明显变化；温度从60 ℃升至90 ℃时

酸值及电阻率的变化幅度较大；温度继续升高

油中开始产生沉淀；温度达到120 ℃时

电阻率已经超出运行油标准要求

说明运行温度是影响磷酸酯抗燃油热氧化安定性的重要因素。对此，提出了磷酸酯抗燃油的运行温度应控制在35~55 ℃，机组启停及正常运行时监控冷油器阀门开度等措施，以避免磷酸酯抗燃油运行中受热氧化

确保调速系统安全运行。
