Abstract
A constriction in a pipeline forces a portion of the pipeline flow to follow a bypass channel wherein it drives a turbine or Pelton wheel before being returned to an output beyond the constriction. In one embodiment, a pump provides a high velocity flow along a second bypass path which is applied through one or more nozzles to accelerate the fluid in the main bypass path.
Claims11
Apparatus for recapturing flow power of a fluid in a pipeline comprising:
- (a) a constriction in said pipeline;
- (b) a first bypass path for directing a first portion of said fluid past said constriction;
- (c) a second bypass path for directing a second portion of said fluid past said constriction;
- (d) means, disposed in said second bypass path, for accelerating a portion of the fluid in said first bypass path;
- (e) means for producing a mechanical output from the fluid in said first and second bypass paths,
- (f) means for returning substantially all said fluid from said first and second bypass paths to said pipeline at a point downstream of said constriction.
