Power cycle working with a mixture of substances

Abstract From the Canadian patent

A power cycle to operate with maximum temperature above 300°C working, with a mixture of water and another substance having lower volatility greater molecular weight and tendency to superheat in the isentropic expan sion. Both substances are vaporized in a boiler in part at variable tem-, perature, and expanded in at least one turbomachine. After the first expansion, a heat yielding takes place at constant pressure wherein part of, the least volatile substance condenses at variable temperature. In comparison with the steam cycle, this new cycle offers higher efficiencies because it has, among others, the advantage of increasing the average temperature of heat absorption, without …
