Tower for a solar concentration plant with natural draught cooling

Abstract

Solar concentration plant placed on tower technology wherein the tower is used not only to equate the receiver devices at great height but also as a natural-draft cooling system. The tower is hollow and has a hyperboloid. structure that may exceed 200 m in height, accommodating devices for receiving saturated or superheated steam in cavities with different orientations. There is a dynamic control for adapting the heliostat field so that the heliostats can be focussed on different focal points for producing electricity, producing process heat, producing solar fuels or for application to thermochemical processes.

1 . Tower for a solar concentration plant with natural-draught cooling having a hollow circular base and hyperboloid structure, wherein it comprises a tower with sufficient height to minimise the cosine effect and having, on its highest part, several rectangular balconies or overhangs with different orientations; each of said balconies or overhangs contains a cavity with an outer opening accommodating one or several solar receiver devices, the construction material of the tower being concrete, metal or an equivalent material, except for the areas adjacent to the outer openings of the cavities, which will be protected by insulating plates, as in the case of the inner areas of the cavities that are not occupied by the solar receiver device. 
     
     
         2 . Tower for a solar concentration plant with natural-draught cooling, according to  claim 1 , wherein the receiver devices may be saturated or superheated steam receiver devices installed independently on the different balconies or overhangs, including a tank by way of connection therebetween. 
     
     
         3 . Tower for a solar concentration plant with natural-draught cooling, according to  claim 1 , wherein the tower exceeds 100 m in height. 
     
     
         4 . Tower for a solar concentration plant with natural-draught cooling, according to  claim 1 , wherein the hollow circular base has a diameter of approximately 50 m, the tower exceeds 200 m in height, the dimensions of the overhangs are approximately 24 m wide by 50 m high and the cavities have an outer opening approximately 20 m wide by 17 m high which accommodates a solar receiver device.
