9FA燃机透平排气分散度高的原因分析及预防对策

Cause analysis and preventive measures for high dispersion of 9FA turbine exhaust gas

对GE公司9FA燃机运行中燃机透平排气分散度高的原因进行分析,并提出对策及措施,以此来提高机组的运行维护水平,避免机组运行中因排气分散度高保护遮断跳机,降低燃机热通道部件损坏风险,使电力生产的安全性显著提高。

It analyzes the reasons for the high dispersion of turbine exhaust gas during the operation of GE 9FA gas turbine,and proposes countermeasures to improve the operation and maintenance level of the unit to avoid the tripping protection triggered by high dispersion of exhaust gas.It reduces the damage risk of the hot channel components of the gas turbine,and significantly improve the safety of power generation.
