ABSTRACT:
Methods for utilizing the heat content of a heated carrier agent are disclosed including indirectly contacting the carrier agent with a working fluid which boils at a temperature lower than water, in order to vaporize the working fluid, producing mechanical energy by expanding the working fluid to a number of reduced pressures, including the condensation pressure of the working fluid corresponding to atmospheric temperature conditions at the time, and a reduced pressure intermediate between the initial elevated pressure of the working fluid and that condensation pressure, separating the working fluid into separate streams corresponding to the working fluid at each of these reduced pressures, condensing the working fluid stream at the lowest pressure by indirectly contacting it with the atmospheric air, condensing the working fluid at the condensation pressure by indirectly contacting it with a liquid heat carrier, and repressurizing both of those working fluid streams for recycle. In this manner the size of these various working fluid streams determines the amount of the heat content of the heated carrier agent used for producing mechanical energy and/or useful heat therefrom.
