Title: SOLAR RECEIVER WITH NATURAL CIRCULATION FOR GENERATING SATURATED STEAM
Abstract:
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 boiler; downpipes through which the recirculation water descends from the boiler to the receiver; and a support pump in order to increase the incident power in the receiver and start up the plant when necessary.
