Abstract
An electric power generating set for a fluid pipeline, comprising a turbine coupled to the pipeline for rotating under the pressure of the fluid moving in the pipeline; a generator coupled to the downstream end of the turbine for generating electric power upon rotation, and a heat exchanger for communicating the fluid from the turbine to the pipeline for absorbing heat from the generator.
Claims8
An electric power generating set for a fluid pipeline, comprising:
- turbine means coupled to the pipeline for rotating under the pressure of the fluid moving in the pipeline;
- generator means coupled to the downstream end of the turbine means for generating electric power upon rotation;
- and
- heat exchange means for communicating the fluid from the turbine means to the pipeline and for transferring heat from the generator means to the fluid, the heat exchange means including bypass pipe means connecting the exit of the turbine means to the pipeline downstream of the generator means and disposed adjacent the generator means for receiving heat by conduction from the generator means.
