With more than 300 bulb units installed worldwide, Alstom has outstanding knowledge and experience in design, manufacturing, installation, commissioning and management of complex bulb projects, whatever the environmental conditions.
Key benefits of bulb hydro turbines
- Most efficient solution for low heads up to 30 meters
- Negligible need for flooding of landscape due to run-off-river type of the operation
- Reduced size, cost and civil works requirements of up to 25% thanks to the straight water passage in the draft tube that improves the hydraulic behaviour of the bulb unit and also results in a lower need for excavation.
- Meet the needs of any particular application - our Bulb turbines also operate as pumps in both flow directions for tidal plant applications
- Sluice operation may also impact favourably both the hydro mechanics and the navigability close to the dam.
