Absorber for a solar receiver and solar receiver comprising at least one such absorber

摘要

The invention relates to an absorber for a solar receiver (R) of a solar power tower, comprising a housing (8), at least one wall (9) of which is to be irradiated by the solar radiation, a core (12) made of at least one material having good thermal conductivity and at least partially surrounded by the housing (8), and a plurality of tubes (10) extending through the core (12) and distributed into a plurality of layers, wherein the tubes extend substantially in a direction parallel to the wall (9) to be irradiated, said tubes (10) being intended for circulating a fluid to be heated, for example a gas for operating a gas turbine.
