Claim:
A boiler for a solar receiver comprising: a) a first boiler wall including upper and lower vertically stacked boiler sections, each boiler section including substantially coplanar side by side boiler panels, each panel of the first wall including an inlet header at one end thereof and an outlet header at an opposed end thereof, a plurality of contiguous panels of the lower section overlapping a plurality of contiguous panels of the upper section, the outlet headers of the contiguous panels of the lower section being proximate to the inlet headers of the contiguous panels of the upper section to fours a header section of the first boiler wall at a first common header elevation; and b) a second boiler wall including upper and lower vertically stacked boiler sections, each boiler section including substantially coplanar side by side boiler panels, each panel of the second wall including an inlet header at one end thereof and an outlet header at an opposed end thereof, a plurality of contiguous panels of the lower section overlapping a plurality of contiguous panels of the upper section, the outlet headers of the contiguous panels of the lower section being proximate to the inlet headers of the contiguous panels of the upper section to form a header section of the second boiler wall at a second common header elevation, wherein the second boiler wall is adjacent to and angled with respect to the first boiler wall so that one end panel of each of the upper and lower sections of the first boiler wall is adjacent to a respective upper and lower end panel of the second boiler wall to form a boiler wall corner, wherein adjacent headers of the end panels of the first boiler wall are at a different elevation from adjacent headers of the end panels of the second boiler wall.
