DEMONSTRATION OF A RADIAL DIFFUSER TURBINE FOR SMALL EXCAVATION DEPTHS

Objective

Demonstration of a propeller turbine with innovative radial diffuser draft tube for reducing excavation work. Expected annual energy output: 600,000 kWh. Plant is to be located at a ship lock to demonstrate its suitability for cascade applications. The estimated payback is 15 years.

A propellor type mini-hydroelectric installation providing 120 kW will be demonstrated at a ship lock of the Twente-Drente coral. The propellor will have 4 blades and a diameter of 1.6 m. The installation is novel in respect of the combining of a hydro plant with a ship lock. In addition the design will minimize operation and maintenance costs.
Net head 4 m
Flow 2 - 6 m3/s
Output power 120 kW
Turbine speed 150 sec/min.
