Best practices for steam turbine maintenance and operation

Steam turbine operation and performance require the correct steam pressure at the turbine inlet and high steam quality (steam without condensate entrapment) to ensure high turbine reliability. The following addresses best practices for optimal steam system turbine maintenance and operation.

Steam Quality Steam must be of the highest quality. Condensate entrapment in the steam supply increases turbine steam rates, reduces the steam turbine efficiency, and causes erosion of steam turbine components (governor valves, blading, and nozzles). Insulating the steam supply lines and components (valves, casing, etc.) helps prevent steam from releasing latent energy, which causes condensation to occur in the steam system.
