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

Molding bench for curving mirrors comprising a sheet () supported on a frame by means of a joint system that prevents the sheet () from shifting and moving and to the lower part of which are fixed a series of air pipes () having a general air header pipe () connected to a vacuum pump. The sheet () consists of a square lattice the intersections of which have perforations that match up with a series of suction points of the air pipes (), intended to produce a vacuum in the bench and which have been previously calibrated, such that said bench can be used to manufacture mirrors having any curvature.

System for manufacturing facets comprising a frame a series of mirrors and multiple securing parts in which said parts are the key to the invention and are formed by a rod and a circular metal sheet provided with a series of small circular perforations, where the rod and the circular sheet are attached by electric arc welding or any other equivalent fixation and the purpose of which is to secure a curved mirror to the rear structure or frame of a heliostat.

System for manufacturing facets for heliostats

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.
