What Is the W251 Series
The W251 Series Gas Turbines are heavy duty industrial turbines designed for reliable power generation and industrial use. Originally developed by Westinghouse for large scale operations, these turbines have been in service since the early 1970s and continue to be widely used across multiple industries.
At Cubical Nexus, we specialize in sourcing and trading components related to the W251 series to support ongoing operations and maintenance needs.
Power Output
The W251 gas turbines typically operate in the 45 to 55 MW range, with a running speed of 5,427 RPM.
The advanced W251B11 model delivers up to 72 MW, engineered for 50 Hz operation and paired with a brush electric generator.
Applications
W251 turbines are used in a wide range of applications, including power generation and industrial manufacturing. Their design supports dual fuel operation, speed ratio control, and inlet guide vane adjustment based on temperature. This makes them suitable for demanding and continuous duty environments.
Series Variations
The W251 series has evolved over time, with several well known configurations, including:
W251B10
An early geared unit in the 20 MW class. This model was the first to introduce cooled turbine flow path components.
W251B11
A higher capacity version producing up to 72 MW, designed for 50 Hz operation and equipped with a brush electric generator.
