Honeycomb ceramic absorbers are considered to be one of the most practical options for the air receiver of a solar central receiver plant. To explore the influence of the average input solar heat flux, air flow rate, and absorber geometric parameters on the honeycomb ceramic air receiver performance, six samples were tested under different conditions and the outlet air temperature, thermal efficiency, and anti-interference characteristics of the receivers were determined. The investigation showed that as the input solar flux or air flow rate increased, the change in the outlet air temperature and thermal efficiency had opposite trends. The sample with the shortest length, thinnest wall, and highest porosity had the best performance. Among the three absorber geometry parameters, the porosity was the dominant factor affecting the receiver outlet temperature and thermal efficiency.

输入太阳能通量、空气流量和吸收器参数对蜂窝陶瓷空气接收器性能影响的实验研究

蜂窝陶瓷吸收器被认为是太阳能中央接收器工厂空气接收器最实用的选择之一。为探讨平均输入太阳能热通量、空气流量和吸收器几何参数对蜂窝陶瓷空气接收器性能的影响，在不同条件下测试了六个样品，并测试了蜂窝陶瓷空气接收器的出口空气温度、热效率和抗干扰特性。确定了接收者。调查表明，随着输入太阳通量或空气流量的增加，出风温度和热效率的变化趋势相反。长度最短、壁最薄、孔隙率最高的样品性能最好。在吸收体的三个几何参数中，
