Experiment Study on the Heating Characteristics of 5kw Focused Solar Simulator

In this paper, a new type 5kW focused solar simulator is designed and also used to heat stirling engine's cylindrical heat receiver. The radiation meter is applied to test the irradiance distribution of the solar simulator's unit light source in course of the test, the heat receiver's wall temperature distribution is obtained by the the data acquisition instrument Agilent 34970A and thermocouples. The experimental measured result indicated that the irradiance distribution on the heat receiver's wall appears Gaussian distribution, the highest irradiance on the wall is 25.1W/cm(2). The highest wall temperature is 600 degrees C, It is generally meet solar stirling engine's laboratory test requirements.
