  • Patent number: 9719696
    Abstract: A solar receiver configuration (receiver) adapted to include a plurality of receiver heat transfer passes. Each pass includes a plurality of panels. Further, each panel includes a plurality of tubes, tangentially arranged, vertically extending between horizontally placed lower and upper headers. The headers, which are pipe assemblies with closed ends, of adjacent panels are horizontally and vertically offset one to another to form a substantially continuous tube surface. Such continuous tube surface enables solar heating of the fluid flow therefrom in at least a parallel flow arrangement and a serpentine flow arrangement.
