ABSTRACT:
Apparatus for producing useful work from available heat at super-ambient temperature. The present apparatus includes a pair of working fluid units which supply pressurized vapor to a utilization apparatus. Each working fluid unit includes a generator for boiling the working fluid in response to available heat, and a recovery vessel for receiving condensed working fluid exhausted from the utilization apparatus after expansion to produce useful work. The condensed working fluid from the utilization apparatus is alternatively returned to the recovery vessel associated with the generator presently receiving heat to generate pressurized vapor.
