Problems solved by technology

[0011] As the tubes are heated and cooled daily during startup, shutdown and cloud passage, such compressive stress is cyclic and will eventually lead to fatigue failure
For receivers using molten salt as the heat transfer fluid, impurities in the molten salt can also cause corrosion, which is more severe where compressive stress is present

Abstract

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. Different tube couplings are possible with this structure, as well as different stiffening structures at the headers. The heat shield can be shaped to create an open space, permitting focusing of sunlight on the edge tubes as well. A curtain can be used as an additional heat shield in certain scenarios.

Description

[0001] Cross References to Related Documents [0002] This application claims priority to US Provisional Application No. 61 / 560,527, filed November 16, 2011. The entire content of this application is hereby incorporated by reference. technical field [0003] The present invention relates generally to the field of solar power generation for generating electrical energy. More specifically, the present invention relates to double exposed or two-sided heat absorbing panels and solar receivers having one or more of said panels. These solar receiver designs can be used in concentrated solar tower technology (also known as concentrated solar power, CSP) to harness the sun's energy to generate "green" electricity. Background technique [0004] The solar receiver is the main part of the solar power generation system, through the solar receiver, the sunlight is used as a heat source to finally generate superheated high-quality steam, which in turn is used to drive a turbo generator,...
