摘要(Abstract)：

为解决9FA燃气-蒸汽多轴联合循环机组启动初期轴封管路暖管缓慢的问题,以加快机组启动进程、提高机组轴封供汽稳定性,在轴封供汽管路上设计加装了轴封电加热器,应用前后的情况表明,该应用具有较好的节能效果。
To solve the slow warm-up of shaft seal piping during the initial startup stage of 9FA gas-steam combined cycle units with multiple axes, electric heater for shaft seal is designed and installed on seal steam supply pipes to accelerate the units start process and improve the steam supply stability for shaft seal of units.The application shows that the electric heater is of favorable energy savings effect.
