Abstract

A boiler for a solar receiver includes a first receiver panel having a plurality of substantially parallel boiler tubes fluidly connecting an inlet header of the panel to an outlet header of the panel. A second receiver panel has a plurality of substantially parallel boiler tubes fluidly connecting an inlet header of the panel to an outlet header of the panel. The boiler tubes of the second receiver panel are substantially parallel to the boiler tubes of the first receiver panel. The first and second receiver panels are separated by a gap. A panel expansion joint is connected to the first and second receiver panels across the gap, wherein the panel expansion joint is configured and adapted to allow for lengthwise thermal expansion and contraction of the receiver panels along the boiler tubes, and to allow for lateral thermal expansion and contraction of the receiver panels toward and away from one another, while blocking solar radiation through the gap.
