摘要
The invention relates to a solar collector having a multi-tube receiver, to thermosolar plants that use said collector and to a method for operating said plants, where the multi-tube receivers have a primary reflector (5) formed by two continuous symmetrical parametric curves, a secondary reconcentrator (6) and a receiver (1) that includes several connected tubes (7) with a circular cross-section, the center of gravity of the collector being located very close to the axis of rotation of the collector itself, and the concentration ratio C/Cmax being greater than 0.63, having 100% collection efficiency and having a maximum of two reflections of solar rays (8). The thermosolar plants that use said multi-tube receivers combine same with cylindrical or trough collectors with a tubular receiver and can be used for the direct generation of steam (with a saturation and overheating zone) or the indirect generation of steam (with the collectors connected in series).
