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

Abstract

Abstract:

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.
