Abstract
An apparatus for increasing the efficiency of a multi-heat source power plant includes a thermal collector having access to heat from a solar collector as a heat source for heating a fluid to a first temperature; a second heat source for heating the fluid; a heat exchanger that transfers heat to the fluid which is heated to said first temperature, to raise the temperature of the fluid to a higher temperature; and a power generation cycle using the fluid, heated to the first temperature, as a motive fluid.
Claims27
An apparatus for increasing the efficiency of a power plant by operating a multi-heat source power plant, comprising:
- a heat exchanger that transfers heat to an organic fluid from a heat source for heating the organic fluid;
- a thermal collector having access to heat from a further heat source comprising a solar collector, that transfers heat to said organic fluid, heated in said heat exchanger, to vaporize the organic fluid at a predetermined temperature;
- and
- a power generation cycle using said vaporized organic fluid as a motive fluid,
- wherein said thermal collector transfers heat from the further heat source to said organic fluid by use of a heat transfer loop capable of limiting the temperature of the heat from the further heat source that is transferred to said organic fluid such that the temperature of the organic fluid reaches the predetermined temperature.
An apparatus for increasing the efficiency of a power plant by operating a multi-heat source power plant, comprising:
- a heat exchanger that transfers heat to a fluid from a heat source for heating the fluid;
- a thermal collector having access to heat from a further heat source that transfers heat to said fluid at a temperature which is variable, to vaporize the fluid at a predetermined temperature;
- and
- a power generation cycle using said vaporized fluid as a motive fluid,
- wherein said thermal collector transfers heat from the further heat source to said fluid by use of a heat transfer loop capable of limiting the temperature of the heat from the further heat source that is transferred to said fluid such that the temperature of the fluid reaches the predetermined temperature.
