A SOLAR RECEIVER WITH A HELIOSTAT FIELD

摘要

A solar central receiver system with a heliostat field comprises at least one solar multi-section receiver 205 to collect concentrated solar radiation 130 and a plurality of heliostats 110 forming the heliostat field 120 comprising a near field 121, which may be extended by an intermediate field 122 and a peripheral field 123, and located on a ground area underneath the solar multi-section receiver 205. The at least one solar multi-section receiver 205 comprises at least two receiver sections 210 being selected from: a cavity receiver section 220 having a cavity 221 with an aperture 222 and inside the cavity a thermal absorber 224; an external thermal receiver section 234 comprising an external absorber 231 on its outer surface; an external photovoltaic receiver section 236 comprising an external absorber 231 on its outer surface. An embodiment of the invention is formed as a solar multi-section receiver with first receiver section 211 as cavity receiver section 220 with a second receiver section 212 with a downwards facing external absorber 231 fully surrounding the aperture 222 of the cavity receiver section 220 and a third receiver section 213 with a cylindrical external absorber 231.
