AI Technical Summary
In the prior art, there is a huge temperature gradient and thermal stress during the preheating process of the molten salt heat absorber of the photothermal power station after icing, which may cause the heat absorbing pipe to bend, deform or rupture, affecting the operation safety of the photothermal power station, and lack effective testing systems and methods to evaluate the preheating performance under icing conditions.
A test system for the preheating performance of molten salt heat absorbers in the photothermal power station was designed, including a support frame, molten salt heat absorber tube screen simulator, thermocouple wire set, data collector, simulated photothermal source, water storage tank and heat flow measurement device. By simulating the preheating process under different icy conditions, the temperature distribution and thermal stress are recorded, and data support and guidance are provided.
The test system can fully reflect the overall preheating effect of the pipe screen, provide data support and guidance, help optimize the preheating process, ensure that the preheating speed and pipe wall stress are within a safe range, and avoid damage to the heat absorbing pipe.
