Abstract
The receiver according to the invention is provided with the heating area for heating a heat-transporting medium, which has an optical opening for sunlight, an absorber absorbing the sunlight arranged within the path of the incidental sunlight and with a transport arrangement for the transport of the medium through the heating area, wherein the absorber is designed as a blackbody radiation arrangement with reduced convection and the transport arrangement for the transport of a gas is designed as a heat-transporting medium. By means of this, the receiver can be designed in a simpler and more reliable manner.
Claims27
A method to operate a receiver with a heating area for heating a heat-transporting medium, and a transport arrangement for the transport of the medium through the heating area, the method comprising:
- providing in the heating area, an opening for the radiation of the sun and an absorber is provided in the path of the incidental radiation of the sun, thereby absorbing the incidental radiation;
- providing a gas absorbing within frequency bands belonging to the infrared range as a heat-transporting medium and that the operating parameters of the receiver are set such that the gas is selected such that a temperature of the gas during transport through the heating area increases due to absorption of radiation such that the ratio of the temperature increase due to the absorption of radiation to the entire temperature increase due to the absorption and convection at the absorber is ≥0.3.
A manufacturing method for a receiver with a heating area for heating a heat-transporting medium and a transport arrangement for the transport of the medium through the heating area, wherein, within the heating area, an optical opening for sunlight is provided and an absorber absorbing the sunlight arranged within the path of the incidental sunlight is provided, wherein the absorber is designed as a radiation arrangement and an absorber area interacting with the absorber is provided, a gas absorbing within frequency bands belonging to the infrared range is provided as a heat-transporting medium in such a way and the absorber area is dimensioned in such a way that, during a predetermined operational state of the receiver, the temperature of the heat-transporting medium flowing operatively through the absorption area increases due to the absorption of the infrared radiation of the absorber in such a way that the ratio of the temperature increase due to absorption in the absorber area to the overall temperature increase due to the absorption and convection at the absorber is ≥0.3.
