ABSTRACT:
A process of mechanical power generation including a binary cycle whose primary cycle works with a mixture of water and another substance of much lower volatility substantially immiscible with water. In the primary cycle, at least part of the vaporization of the water is accomplished by means of the heat yielded simultaneously by condensation at variable temperature of the substance of high boiling point. This binary cycle allows obtaining much higher efficiencies than conventional cycles in small power plants (up to 50 MWe), thanks to the diminishing energy losses in the heat absorption, optmising the expansion efficiencies with simple turbines and substantially eliminating the vacuum in the installation. The proposed cycle has better partial load efficiency and lower response time than conventional cycles, with similar cost.
