Abstract

The possibilities of using single-mirror small solar furnaces (SSFs) with concentrators made of spotlight mirrors in high-temperature materials science are investigated. Calculated estimates of the optical-energy characteristics (OECs) of spotlight mirrors as SSF elements (average concentrations and flux distribution in the focal plane depending on the mirror inaccuracies) are carried out. Experimental studies of SSFs with a spotlight mirror with a diameter of 2 m and an opening angle of 60° showed that they can provide average flux densities of concentrated solar radiation up to 600–700 W/cm² on a working spot with a diameter of up to 10–15 mm and provide heating temperatures above 3000 K. The results of the study show the possibilities of using SSFs with a parabolic spotlight mirror with a diameter of 2 m in high-temperature materials science, both at the research stage and at the stages of developing the technology for obtaining functional materials in the Large Solar Furnace.

小型单镜太阳能炉的光能特性和加热温度

探讨了高温材料科学中使用聚光镜聚光器的单镜小型太阳炉的可能性。计算估计了聚焦镜作为SSF元件的光能特性（平均浓度和通量分布在焦平面上取决于反射镜精度）。采用直径为2 m、开口角为60°的聚光反射镜进行的实验研究表明，在直径为10-15 mm的工作点上，其集中太阳辐射的平均通量密度可达600-700 W/cm2，加热温度可达3000 K以上。研究结果表明，在高温材料科学中，无论是在研究阶段还是在开发在大型太阳炉中获得功能材料的技术阶段，使用直径为2米的抛物面聚光镜的ssf的可能性。
