초록 ▼

Solar concentrator plant using natural-draught tower technology, in which the tower is, in turn, used as cooling system. The tower houses saturated or superheated steam receivers in cavities with different orientations, with adaptive dynamic control of the heliostat field in order to direct said receivers towards different focusing points, for the production of electricity, process heat or solar fuels or for use in thermochemical processes.

대표청구항 ▼

1. A solar concentrator plant using natural-draught tower technology, comprising: a field of heliostats reflecting solar radiation; anda hollow tower tall enough to minimize a cosine effect, the hollow tower including: a hyperboloid structure;at least one condenser surrounded by air at room temperature within a base of the hollow tower, wherein the condenser is cooled by the room temperature air, which moves upward through the tower due to natural draught;a plurality of solar receivers located at a top of the hollow tower;a plurality of cantilevered modules including a plurality of cavities within the cantilevered modules at an upper final section of the tower, wherein the plurality of cavities house the solar receivers and are integrated with the hollow tower, such that equipment within the cavities does not hinder the natural-draught effect for the cooling of the condenser;each of the plurality of solar receivers is independently located in each of the cantilevered modules having different orientations, so as to allow independent point control strategies of the heliostat field having several focal points for different cavities. 2. The solar concentrator plant using natural-draught tower technology according to claim 1, further comprising: saturated steam receivers disposed in the cantilevered modules;superheated steam receivers disposed in the cantilevered modules; anda boiler as a connection between the saturated steam receivers and the superheated steam receivers. 3. The solar concentrator plant using natural-draught tower technology according to claim 2, wherein: the heliostat field is oriented North, andthe plurality of cavities include three cavities oriented as follows in order to maximize steam production: a Southeast cavity that includes at least one of the saturated steam receivers;a West cavity that includes at least one of the saturated steam receivers; anda North cavity that includes at least one of the superheated steam receivers. 4. The solar concentrator plant using natural-draught tower technology according to claim 2, wherein: the heliostat field has a circular configuration,the cantilevered modules are arranged around an outer diameter of the hollow tower, andthe plurality of cavities include four cavities oriented as follows, in order to maximize steam production: an East cavity that includes at least one of the saturated steam receivers;a West cavity that includes at least one of the saturated steam receivers;a North cavity that includes at least one of the superheated steam receivers: anda South cavity that includes at least one of the superheated steam receivers. 5. The solar concentrator plant using natural-draught tower technology according to claim 1, further comprising a storage system. 6. A method for operating of a solar concentrator plant using natural-draught tower technology as that described in claim 1, comprising: directing water heated by solar radiation through tubes of an evaporator in a steam receiver;obtaining saturated steam at approximately 300° C. at an evaporator outlet;transferring the saturated steam to a boiler;obtaining dry steam in the boiler by water-steam separation;directing the dry steam from the boiler to a superheater;obtaining superheated steam by raising the temperature of the dry steam up to approximately 540° C. in the superheater by using solar radiation;directing the superheated steam into a turbine in order to generate electricity;directing the superheated steam that has passed through the turbine to pipes of a condenser;obtaining condensed steam by cooling the superheated steam by a stream of air flowing along the pipes of the condenser, wherein the temperature of the stream of air is increased in the condenser; the stream of air rising by an action of a natural-draught chimney of the hollow tower, exiting the hollow tower through a top of the hollow tower; and the condensed steam exiting the condenser as water through an outlet of the condenser; andpumping the water to the receivers at the top of the hollow tower. 7. The solar concentrator plant using natural-draught tower technology according to claim 5, wherein the storage system comprises spherical tanks. 8. The solar concentrator plant using natural-draught tower technology according to claim 7, wherein the spherical tanks include water-vapor tanks. 9. The solar concentrator plant using natural-draught tower technology according to claim 7, wherein the spherical tanks include molten salts tanks.
