摘要

摘要 研究了大型太阳灶(LSFs)焦平面上的太阳辐射聚光密度和通量,同时考虑了总体参数、聚光器和定日镜切面的误差以及定日镜场对太阳光的遮挡和阻挡。研究发现,LSF 可以全年每天有效工作 8 小时。结果表明,当 LSF 焦点处的辐照度与极限值相差 0.6 时,角度误差 σ 的均方根误差 (RMS) 约为 7 角分,如果它们相等,则每个平面分量(有 8 个)的偏差可达 ±4.2 角分,如果在 σ 范围内,则可以重新分配。面聚光器曲率半径误差(积分误差)的负常数分量对 LSF 聚焦处的辐照度有很大影响,它不应小于-0.2。

Optical Energy Characteristics of Large Solar Furnaces

Abstract

The densities and fluxes of concentrated solar radiation in the focal plane of large solar furnaces (LSFs) are studied, taking into account the overall parameters, inaccuracies in the facets of the concentrator and heliostats, and shading and blocking the sun’s rays by the fields of heliostats. It was found that LSFs can work effectively for 8 h a day throughout the year. It is shown that when the irradiance in the focus of the LSF is 0.6 from the limit, the root mean square error (RMS) of angular inaccuracies σ can be about 7 ang. min, and, if they are equal, each flat component (there are eight of them) can have deviations up to ±4.2 ang. min, which if within σ, can be redistributed. The negative constant component of the inaccuracies of the curvature radius (integral inaccuracy) of the facet concentrator has a strong influence on the irradiance in the focus of the LSF, it should not be less than –0.2.
