Descrition:
The bulb turbine is a reaction turbine of Kaplan type which is used for extremely low heads from 2m to 20m.
The feature of this turbine is that the upstream have a watertight casing which contains a generator located on a horizontal axis, the case shape is like a bulb, so it is called bulb turbine.
The bulb turbines have higher full-load efficiency and higher flow capacity as compared to Kaplan turbine.
The Bulb Tubular turbine is the best selection for exploitation of tidal power and hydraulic power with extremely low water head and extremely large discharge. It has large discharge, high specific speed and high efficiency, and needs less excavation in civil works.
Applications:
1. Water head: from 2m to 20m
2. Capacity: 100kw to 10MW
3. Runner diameter: 0.4 to 5m
