Scope
GB/T 41307-2022 is the English-translated version of 塔式太阳能热发电站吸热器检测方法.
GB/T 41307-2022 gives the test methods for the receiver of a solar power tower plant.
It describes the inspection of appearance and dimensions, the inspection of the welds, the stiffness test, the pressure test, the adhesion test of the coating, the measurement of reflectance and absorptance, the measurement of thermal power and efficiency and the molten salt drainage test.
It applies to tower receivers using molten salt or water and steam as the heat transfer medium. Receiver makers, plant owners and the engineers who accept the equipment use it, with the requirements themselves in GB/T 41303-2022. Issued on 9 March 2022, it has applied since 1 October 2022.
