W251 Gas Turbine Parts
What Is The W251 Series?
The Westinghouse W251 Series Gas Turbines are single-shaft, axial-flow heavy industrial machines, originally developed by the Westinghouse Electric Corporation’s Power Generation Business Unit. These turbines, introduced around 1970, have been integral to various industrial manufacturing and power generation applications.
Power Output
The W251 turbines are in the 45-55 MW class, operating at a speed of 5,427 RPM. Notably, the W251B11 variant offers a higher power output of 72 MW, designed for 50 Hz operation with a brush electric generator.
Application
These turbines have been utilized in diverse settings, including as gas turbine generator drives. Their design supports on-line dual fuel control, speed ratio control, and inlet guide vane control based on temperature, making them versatile for both power generation and industrial manufacturing processes.
Variations
The Westinghouse 251 Series Gas Turbines have evolved since their introduction around 1970, with the current configuration being the B8. Some of the known variants include
- W251B10: This variant was a geared 20MW-class unit and was the first gas turbine to feature cooled turbine flow-path components.
- W251B11: This is a larger variant with a power output of 72 MW. It operates with a brush electric generator and is designed for 50 Hz operation.
