Francis hydraulic turbine
Alstom Power Generation
Francis turbines generally are the most efficient solution for heads ranging from 40 to 600 meters. The runner design can be adapted to get the highest level of efficiency in its whole range of application.
Francis turbines are very robust and able to sustain the high mechanical stress resulting from high heads.
Alstom has successfully completed numerous installations of Francis turbines with outputs up to 800 MW. In fact, we've manufactured the largest Francis turbines ever made - each runner has a diameter of 10 meters and weighs 450 tons - for the Three Gorges Project in China.
Older hydropower plants benefit directly from our ongoing efforts to increase efficiency, output and safety of our Francis turbines. In refurbishment applications, the improved overall performance offers a highly competitive solution for increased profit generation.
