Vertical Francis turbine
DESIGNED FOR PURPOSE
ForwardHydro 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. Forwardhydro Francis runners can be offered fully machined from a single forged block or as a casting solution.
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.
Forward Hydro Francis model range includes 8 different specific speed designs. The Hydro team at Forwardhydro can advise on the best solution for your project.
