Kaplan turbine


Kaplan turbine

Austrian engineer Viktor Kaplan (1876-1934) invented this turbine. It's similar to the propeller turbine, except that its blades are adjustable; their position can be set according to the available flow. This turbine is therefore suitable for certain run-of-river generating stations where the river flow varies considerably. The Kaplan turbine is similar to the propeller turbine except that its blades are adjustable.

Each Kaplan turbine at Brisay generating station weighs 300 tonnes... That's the weight of 50 African elephants.

Propeller turbine
Since they can reach very high rotation speeds, propeller turbines are effective for low heads. Consequently, this type of turbine is suitable for run-of-river power stations.
