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.

A steam generator includes a furnace configured and adapted to generate a stream of furnace exit gases from the combustion of municipal solid waste fuel. At least one superheater is disposed within an upper portion of the furnace or backpass. The superheater is configured and adapted to superheat fluids within the superheater by facilitating heat transfer between fluids within the superheater and furnace exit gases outside the superheater. At least one waterwall furnace platen is disposed within the furnace upstream from the superheater, the waterwall furnace platen is configured and adapted to lower furnace exit gas temperature at the superheater by facilitating heat transfer between fluids within the waterwall furnace platen and furnace exit gases outside the waterwall furnace platen.
