“…Для керамических материалов скорость нагрева составляет сотни градусов в секунду. Исследования на БСП позволяют оценить воздействие высокой температуры на свойства и структуру теплоизоляционного ККМ, определить влияние характеристик материала на его теплоизолирующие свойства, оценить вклад воздействия температуры на морфологию и деструкцию материалов в условиях нагрева в отсутствии скоростного напора [4,5].…”

This chapter presents a method of calculation of the energetical characteristics of the large solar furnace with a capacity of 1000 kW (LSF) taking into account its real optical parameters. The technical characteristics of the LSF are presented. The possible energy characteristics of the LSF based on numerical calculations are analyzed. The energy characteristics of the total system with different inaccuracies of the reflecting surfaces, energy contributions of certain shelves and groups of heliostats, and the contributions of certain heliostats and shapes of their focal spot are determined. Empirical formulas are proposed to describe the obtained numerical results. The problem of implementing the possible energy modes of the LSF with and/or without the inclusion of certain shelves and groups of heliostats is analyzed. The problem of a day changes in the energy density distribution in the focal spot of the LSF is considered.

“…The off-axis focusing device involves the use of heliostat to focus sunlight onto a fi xed receiver in the systems such as the central power tower, the solar furnace, etc. [2][3][4][5][6][7]. The on-axis focusing devices are usually used for distributed and smaller scale power generation (in the range from several kW to tens of kW) compared to that of off-axis focusing devices in the application of a central receiver system.…”

Overcoming astigmatism has always been a great challenge in designing a heliostat capable of focusing the sunlight on a small receiver throughout the year. In this chapter, a non-imaging focusing heliostat with dynamic adjustment of facet mirrors in a group manner is presented for optimizing the astigmatic correction in a wide range of incident angles. Non-imaging focusing heliostat that consists of m × n facet mirrors can carry out continuous astigmatic correction during sun-tracking with the use of only (m + n -2) controllers. A further simplifi ed astigmatic correction of non-imaging focusing heliostat is also discussed which reduces the number of controllers from (m + n -2) to only two. A detailed optical analysis is carried out and the simulated result has shown that the two-controller system can perform comparably well in astigmatic correction with a much simpler and more cost effective design. The new heliostat is not only designed to serve the purpose of concentrating sunlight to several hundreds of suns, but also to signifi cantly reduce the variation of solar fl ux distribution with incident angle.
