Horizontal Francis turbine with duble runner H=14.2 m Q=2.5 m3/s P=310 kW
For our customer, we designed, supplied and installed all the electrical and mechanical equipment for a plant on the Tržiška Bistrica river, complete from the concept design to facility commissioning.
The set is equipped with a Francis turbine with a double runner. Such a configuration offers a number of advantages over a common single runner configuration (it allows twice the flow rate, axial load forces are eliminated, the turbine can run at higher revolutions, the economic performance is much more favourable etc.).
The machine room is also fitted with a bypass line to maintain a constant flow rate in the piping in the event of a set shutdown. This solution avoids the risk of excessive overflow, in the event of a turbine shutdown, at the intake area, which is restricted in capacities due to existing infrastructure and limited space.
