Abstract
For operating a multi-heat source power plant, including a thermal collector having access to heat from a solar collector as a first heat source for heating a first fluid to a first temperature, a topping power generation cycle using the first fluid as a motive fluid, and a geothermal second heat source for heating a second motive fluid, which is different from said first motive fluid, to a second temperature lower than the first temperature, a heat exchanger transfers heat from the first fluid to the second fluid to raise the temperature of the second fluid to a higher temperature. A bottoming power generation cycle uses said second fluid, heated to the higher temperature, as a motive fluid.
Claims9
An apparatus for increasing the efficiency of a power plant by operating a multi-heat source power plant, comprising:
- a thermal collector having access to heat from a solar collector as a first heat source for heating a first fluid to a first temperature;
- a topping power generation cycle using said first fluid as a motive fluid;
- a geothermal second heat source for heating a second motive fluid, which is different from said first motive fluid, to a second temperature lower than the first temperature;
- a heat exchanger that transfers heat from said first fluid to said second fluid to raise the temperature of said second fluid to a higher temperature;
- and
- a bottoming power generation cycle using said second fluid, heated to the higher temperature, as a motive fluid.
