Abstract
A dual-cycle heat engine employing a first cycling working fluid and a second cycling working fluid whose cycles overlap when fused into a combined working stream so as to preserve compression heat generated during compression of the first working fluid thereby yielding enhanced work extraction when complying with additional thermodynamic requirements.
Claims19
A method of exploiting compression heat during work generation in heat-engines, the method comprising:
- providing a dual-cycle, heat engine having a first working fluid circulating in a first cycle and a second working fluid circulating in a second cycle;
- generating compression heat in the first working fluid;
- combining the first working fluid and the second working fluid into a combined working stream so as to preserve the compression heat in the combined working stream;
- vaporizing the combined working stream through heating into a vaporized combined working stream;
- and
- expanding the vaporized, combined working stream so as to extract work.
3 more elements
A dual-cycle, heat engine comprising:
- a first working fluid circulating in a first cycle and a second working fluid circulating in a second cycle;
- a compressor in communication with the first working fluid and the second working fluid, the compressor operative to compress the first working fluid such that compression heat generated in the first working fluid is preserved in a combined working stream formed from the first working stream and the second working stream;
- a heater operative to vaporize the combined working stream into a vaporized combined working stream;
- and
- at least one adiabatic expander configured to expand the vaporized combined working stream so as to extract work.
