Solar receiver with dual-exposure heat absorption panel

摘要

A dual-exposure heat absorption panel is disclosed, which can be used in a solar receiver design. Generally, the heat absorption panel includes a tube panel through which a heat transfer fluid is flowed to absorb solar energy from heliostats that are focused on the tube panel. A structural support frame surrounds the tube panel. A stiffener structure runs across the exposed faces of the tube panel. The headers and other support structures on the periphery are protected by use of a heat shield.

主权项

1. A dual-exposure heat absorption panel, comprising:
a tube panel comprising a plurality of vertical tubes for conveying a first heat transfer fluid, wherein the tubes are interconnected by at least one upper header and at least one lower header, and wherein the tube panel has a first exposed face, an opposite second exposed face, an upper edge, a lower edge, a first side edge, and a second side edge; and a structural support frame that runs along the upper edge, the first side edge, and the second side edge of the tube panel; and a first stiffener structure running from the first side edge to the second side edge across the first exposed face and the second exposed face of the tube panel at a first support elevation, and back to the first side edge at a second support elevation; wherein the first stiffener structure is formed from a first support assembly and a second support assembly; wherein each support assembly includes a support tube for conveying a second heat transfer fluid, a horizontal flange extending from the support tube and having a slot therein, and a scallop bar engaging one or more vertical tubes of the tube panel and having at least one lug, the scallop bar engaging the horizontal flange by a pin passing through the at least one lug and the slot of the horizontal flange.
