A device for compressing gas using thermal energy. In a subsonic embodiment the heat gas passes through a convergent pipe C 1 where it is provided with operating velocity, a convergent pipe C 2 where it is simultaneously maintained at high speed and cooled by evaporation of liquid sprayed by nozzles R with adjustable position distributed in C 2. In a supersonic embodiment, the gas reaches sonic velocity at the throat of C 2 and supersonic velocity in a divergent DG, then compressed in a convergent CG 1 and simultaneously cooled by evaporation of sprayed liquid. In both embodiments, the gas is finally compressed in a subsonic divergent DG 1. Pipes with variable geometry enable to modify the cross-sections of the throats of the device. The device is essentially designed for thermoelectric power stations. |
