Abstract:

The aim of this project is to increase the efficiency of the short height stages typically found in high pressure steam turbine cylinders. This will directly lead to a reduction in the amount of coal required to produce electrical power, resulting in lower power station emissions. In order to do this, the following tasks must be undertaken:

Increase the accuracy and execution speed of in-house CFD codes

Develop new Computer Numerically Controlled (CNC) techniques to efficiently produce model turbine blade rows with highly curved 3-D blades

Optimise existing 3-D fixed blade designs to improve performance and gain better understanding of how to deal with very short height blading

Produce a novel design for very short height fixed blades

Perform a model air turbine test on the new design of fixed blade to assess the performance benefit gained from it

The benefits of the project include:

Reduces power station emissions through more efficient use of fuel

Keeps the UK steam turbine industry at the forefront of technology

Increases the value of retrofit solution offered to customers (typically £700 per kilowatt)

Maintains ALSTOM's competitive advantage in the impulse retrofit steam turbine market. Last year ALSTOM won overseas orders worth over £42 million in this area of the company's business
