Abstract

Land based Gas Turbine (GT) engines are used very widely in power generation plants. The performance of the turbine blades greatly influences the engine’s overall efficiency and service life. As turbine engines operate, the life and performance of the blades are degraded by the deposition of material. Deposits can come from dirty fuels or eroded components or from airborne particles in the environment.1 Filters have been created for GT engines in an effort to screen out such particles. When particles are ingested into the GT engine and infiltrate these filters they become molten and stick to the turbine blade surfaces. As these deposits build up they increase the aerodynamic drag and raise the temperature of the blades.
