Concentrating Solar Collector for Drying Process

건조가공용(乾燥加工用) 태양열(太陽熱) 집열장치(集熱裝置)에 관(關)한 연구(硏究)

A concentrating solar collector of parabolic-cylindrical type is designed and constructed to provide a heat source of higher temperature for drying processes. Usually collectors of concentrating type require such peripheral auxiliary units as solar tracking system, heat medium circulation pump and temperature controller. However in this study, for simplification's sake in the maintenance of a collector system, it is intended to design a concentrating collector system which does not furnish these auxiliary units by adapting natural circulation system instead of foced circulation and by adjusting collector system to solar altitude manually and periodically. And based on the experimental data, a conceptual design for a heat sources of 50KWt thermal output is presented and discussed.
