Design and experimental measurement of sunlight concentration and transmission of a multifunctional solar furnace

A low-cost solar furnace with adjustable power was designed and developed, which consists of a parabolic concentrator, a shutter and a reflective plane.By establishing the model of sunlight’s concentration and transmission of the solar furnace, its photothermal conversion performance received both theoretical analysis and experimental measurement with the infrared imaging method. Results show that this furnace has very good concentration and adjustment of solar energy, and the density of the focal spot’s energy flow varies with the sine of the shutter’s blade angle.The figure of the focal spot is quite steady and clear when the temperature of the concentrated solar flux spot is about 140℃. The conclusions are useable for the research and development of solar furnaces.
