FRANCIS TURBINES

HEAD RANGE: up to 400m

POWER OUTPUT: up to 20MW

The Francis Turbine is one of three options in the Gilkes range.

Gilkes Francis Turbines are available as either horizontal or vertical units. The water enters the spiral, or scroll case, and is directed by a series of moveable guide vanes, or wicket gates, to the turbine runner.

As the water passes through the runner it rotates and the water pressure drops. Water is then discharged through a draft tube into the tailrace. Flow is controlled by opening or closing the guide vanes, using electric or hydraulic actuators, which, are self controlled by either a speed governor, for stand-alone duty, or, PLC control for parallel operation with the distribution grid.

Gilkes Francis model range includes 8 different specific speed designs. The Hydro team at Gilkes can advise on the best solution for your project.
