Abstract
An in-pipe turbine with the use of an air bubble in a new and unique configuration with electronic controls can improve the efficiency of in-pipe hydroelectric turbines.
Claims20
A hydroelectric system in a pipe containing a fluid, with a connected generator for electrical output, comprising:
- a. A casing enclosing a turbine with at least one blade and connected to at least one input and output pipe,
- b. A gas pressure means providing substantially continuous gas pressure to the interior of the casing through at least one gas nozzle, operative to keep the turbine blades substantially free of back-flow water.
A method of keeping the blades of an in-pipe turbine system in a casing substantially free of water by the steps of
- a. Placing a microprocessor control system to regulate the pressure in the system with at least one of the following set of connected components:
- liquid level sensor, liquid pressure sensor, gas pressure sensor, gas compressor, and needle valve system,
- b. Introducing an air bubble into the casing.
