The invention relates to a solar receiver with natural circulation for generating saturated steam, which uses water/steam as a heat-transfer fluid and includes a combined circuit for fluid recirculation (forced circulation and natural circulation). The system comprises: water-walls which receive the radiation on the surface thereof and inside which the working fluid changes phase; riser pipes through which the water/steam mix exiting the pipes of the receiver rises towards the drum; downpipes through which the recirculation water descends from the drum to the receiver; and a support pump in order to increase the incident power in the receiver and start up the plant when necessary.

Solar receiver with natural circulation for generating saturated steam

A solar concentration plant which uses water/steam as a fluid, in any thermodynamic cycle for the exploitation of process heat, comprising an evaporation subsystem, where saturated steam is produced, a superheater subsystem through which the steam reaches the required conditions of pressure and temperature at the turbine inlet, and an attemperation system interconnected by a drum. A field of heliostats is pointed towards either of the subsystems (evaporator or superheater), in such a way to control both the pressure within the drum and the outlet temperature of the superheated steam.

Solar concentration plant for the production of superheated steam

A solar concentration plant which uses water/steam as a heat-carrying fluid, in any thermodynamic cycle or system for the exploitation of process heat, which is comprised of an evaporation subsystem, where saturated steam is produced under the conditions of pressure of the system, and a superheater subsystem through which the steam reaches the required conditions of pressure and temperature at the turbine inlet, and in which an attemperation system () may be incorporated, these being physically separated and interconnected by means of a drum () in which the separation of water and steam takes place, and in which a strategic control of the pointing of the field of heliostats () towards either of the subsystems (evaporator or superheater) may be carried out, with individual or group pointing of the heliostats, in such a way that they jointly control both the pressure within the drum () and the outlet temperature of the superheated steam ().

Solar tower

Which, using a heat transfer fluid in any thermodynamic cycle or system for using process heat, comprises: In a specific application for generating electric power, the two-dimensional solar concentrator means consist of a parabolic trough collector (), while the three-dimensional solar concentrator means consist of a heliostat field and central tower () for generating overheated steam that expands in a turbine () coupled to an electric generator ().
