The linear fresnel reflector (LFR) with secondary reflector has more uniform solar radiation distribution on the receiver surface, but it increases shelter between receiver and reflector. In this article, the shielding of the designed LFR with secondary reflector was analyzed by theoretical calculation and simulation. Firstly, the range of shielding angle θni between second reflector and the west three primary mirrors was obtained by theoretical calculation. Then, the number of received rays of primary mirrors was simulated by using the ray-tracing with or without the installation of secondary reflector. According to the change of numbers, it showed that the range of shielding angle of west three mirrors were 70º ~ 90º, 54º ~ 72º and 42º ~ 58º, respectively. In addition, loss rate of rays was used to evaluate the shielding effect of secondary reflector, it showed that the maximum loss rate of rays was 23.35% with the secondary reflector.
Key words： Linear Fresnel Reflector; receiver; shielding; the shielding angle
