LOW HEAD TURBINES

Application range:

  • heads from 1.5 m to 30 m
  • outputs from 100 kW to 20 MW
  • runner diameters up to 6 000 mm


Types:

BULB turbines

  • horizontal axial flow turbines equipped with a diagonal distributor and a straight cone draft tube
  • enable to achieve high discharge and thus also output at low head of hydro power plants
  • the direct driven generator is located in a bulb like casing  braced with columns and ribs


PIT turbines

  • they are similar to the BULB turbines
  • high speed generator is driven by a speed increaser located  in the turbine pit
  • these turbines make even very low head power plants cost effective


S-type tubular turbines

  • horizontal S- type turbines equipped with diagonal distributor and S – type draft tube
  • the shaft is conducted  through  the elbow to the generator
  • draft tubes can be designed with one or  two elbows


Vertical axial flow turbines

  • vertical axial flow turbines equipped with diagonal distributor are arranged with the generator located over the turbine
  • the shaft is conducted through the turbine  inlet elbow to the generator
  • draft tube can be of a straight type or with one elbow (SAXO - type turbine)
