摘要/Abstract

摘要： 介绍了GE 公司S109FA 联合循环机组在启停过程中容易出现的异常问题，如冷态开机投旁路时跌真空，高压旁路撤出时高压旁路控制阀关不严密、泄漏，过热器减温器疏水在低负荷时达不到自动关定值，汽机本体疏水箱水位低、跌真空，凝结器循环水二侧出口温度偏差大等，针对上述问题提出了相应的处理方法。

Abstract: The abnormal problems occurred frequently in starting and shutting process of S109FA tandem combined cycle unit manufactured by CE Corporation. These problems were as follow: the vacuity dropped when by-pass put in operation during cold starting, the control valve of high pressure by-pass closed no tightly and leaked when high by-pass quitted, the drain pressure of desuperheator can not achieved auto-close set point in operation with low load, the level in the drain tank of steam turbine proper lowered and vacuity dropped, the circulating water temperature deviation on the second outlet of condenser increased. The relevant handling methods for solving the problems mentioned above were put forward.

Key words: gas turbine, combined cycle, starting and shutting process, abnormality handling
