Abstract
The present invention provides a device which comprises: a heat exchanger (1) for transferring heat of a heat-supplying medium to a working medium which differs from said heat-supplying medium, a first supply device designed to provide a flow of the heat-supplying medium at a first temperature from a heat source to the heat exchanger, and a second supply device which is designed to deliver the heat-supplying medium after it has passed through the heat exchanger, and/or a further medium at a second temperature lower than the first temperature, to the flow of the heat-supplying medium at the first temperature.
Claims19
Organic Rankine Cycle apparatus, comprising:
- a heat exchanger for transferring heat of a heat-supplying medium to an organic working medium which differs from the heat-supplying medium;
- a first supply device adapted to supply a flow of the heat-supplying medium having a first temperature from a heat source to the heat exchanger;
- a second supply device adapted to supply at least partially the heat-supplying medium, after the heat-supplying medium has passed through the heat exchanger, and/or a further medium, each of the heat-supplying medium and the further medium having a second temperature that is lower than the first temperature, to the flow of the heat-supplying medium having the first temperature such that the temperature of the heat-supplying medium at the heat exchanger lies below a decomposition temperature of the organic working medium;
- and
- a device adapted to heat or cool the heat-supplying medium, after the heat-supplying medium has passed through the heat exchanger, and/or the further medium to the second temperature before the heat-supplying medium, after passing through the heat exchanger, and/or the further medium is supplied to the flow of the heat-supplying medium supplied from the heat source to the heat exchanger.
Apparatus, comprising:
- a heat exchanger for transferring heat of a heat-supplying medium to an organic working medium that differs from the heat-supplying medium;
- a first supply device adapted to supply a flow of the heat-supplying medium having a first temperature from a heat source to the heat exchanger;
- a second supply device adapted to supply a further medium having a second temperature that is lower than the first temperature to the flow of the heat-supplying medium having the first temperature such that the temperature of the heat-supplying medium at the heat exchanger lies below a decomposition temperature of the organic working medium, and
- wherein the heat-supplying medium is or contains flue gas.
Method for evaporating an organic working medium in an Organic Rankine Cycle thermal power plant, comprising the steps of:
- supplying the organic working medium in a liquid state to a heat exchanger,
- supplying a heat-supplying medium having a first temperature, the heat-supplying medium differing from the organic working medium, from a heat source to the heat exchanger,
- recirculating at least a portion of the heat-supplying medium, after the heat-supplying medium has passed through the heat exchanger, having a second temperature that is lower than the first temperature, and/or supplying a further medium having the second temperature which is lower than the first temperature into the flow of the heat-supplying medium supplied from the heat source to the heat exchanger such that the temperature of the heat-supplying medium at the heat exchanger lies below a decomposition temperature of the organic working medium, and
- cooling or heating the heat-supplying medium, after the heat-supplying medium has passed through the heat exchanger, and/or the further medium to the second temperature before the heat-supplying medium, after being passed through the heat exchanger, and/or the further medium is supplied to the flow of the heat-supplying medium supplied from the heat source to the heat exchanger.
