Kaplan turbine

...................................................................................................
Kaplan turbines are widely used throughout the world for electrical power production. They cover the lowest head hydro sites and are especially suited for high flow conditions.



Francis turbine in the three gorges dam

...................................................................................................
The Francis turbine is a reaction turbine,which means that the working fluid changes pressure as it moves through the turbine, giving up its energy.A casement is needed to contain the water flow.The turbine is located betweenthe highpressure water source and the low pressurewater exit, usually at the base of a dam.



Bulb turbine

...................................................................................................
Bulb or Tubular turbines are designed into the water delivery tube. A large bulb is centered in the water pipe which holds the generator, wicket gate and runner. Tubular turbines are a fully axial design, whereasKaplan turbines have a radial wicket gate.
