Turbine for hydro-electric power station, has case traversed by opening having cylindrical portion, and wheel having blades arranged at level of portion, where rotating speed of wheel is less than specific turns per minute

摘要

The turbine has a case (32) traversed by an opening that includes a cylindrical portion. A wheel (34) has blades (48) that are arranged at the level of the cylindrical portion. The ratio between the kinetic energy of the water flow and the potential energy of head is less than 20 percentage, and the rotating speed of the wheel is less than 50 turns per minute. An independent claim is also included for a hydro-electric power station comprising a turbine.
