| Abstract: | In order to solve the problem of shift focal line and reduce the energy consumption of solar tracking during the single axis tracking of linear Fresnel solar collector system,a fixed linear focus Fresnel lens solar concentrator was proposed.This solar concentrator combines polar tracking with linear Fresnel lens regular sliding adjustment to achieve fixed linear focus.Combined the solar concentrator and triangular cavity receiver into a solar collector system,the optical efficiency of the system and the flux density distributions of absorption surface in triangular cavity receiver were investigated by the optical software TracePro based on Monte Carlo ray tracing method under different solar declination angles and different tracking error angles,respectively,when with and without slip adjustment.The results show that the minimum optical efficiency of the fixed linear focus Fresnel lens solar system with slip adjustment for one year is 51.29%,which is 22.79%higher than that without slip adjustment. |
