The Kaplan turbine: a power package for reduced height of fall
1913 the Austrian engineer Viktor Kaplan developed the Kaplan turbine, according to the basics of the Francis turbine. This turbine is excellent for small fall heights (from 1 to 15 metres) and for big water flow rates. A typical application example are the river hydraulic power stations.
The mode of operation of the Kaplan turbine
The Kaplan turbine is almost exclusively built in the vertical axle type, since the optimal water flow direction in the turbine is top-down. The incoming water is deflected through the pipelines, so that the turbine efficiency can be adjusted according to the request and the water volume. The water is displaced and hits the guide blades which leads the water towards the runner blades parallel to the shaft, supplying energy to the generator. These runner blades of the Kaplan turbine can be so oriented, that the turbine achieves a high level of efficiency over a large load range.
