Pressure reduction turbine

The pressure reduction turbine in a coaxial feeding instead of the standard spiral feeding is capable to fulfill all requirements, flow-wise and strength-wise. It helps to use the pressure drop for elecricity production instead of simply warming water in pressure reduction valves and contributes therefore for environmental protection.

The flat coaxial feeding was developed for flow optimization simultaneously with the strenght development. It was an intensiv iteration process to achieve the best values for both demands, which are mostly contratictive. The pressure reduction turbine is the best compromise for the Q-demand and efficiency demand.The developed Shell Diagram shows the capability and the cavitation limit as well as a wide range of high efficieny.
