Solve Stove

Frenchman Muxiao, designer of worldwide first set solar stove, developed the parabolic solar stove ordered by the king of France in 1860 for the army¡¯s utilization in Africa. Since the 1900s, many countries conducted the research on solar stove, among which some tapped indoor solar stove by use of heat-pipe technologies and optical theory. But in general, the utilization on solar stove was in small scale in the world.

The Chinese first solar stove emerged in Shanghai in 1956. Under the efforts in several decades, solar stoves have been kept in a amount of more than 300,000 sets in China making it possible to be the country that has popularized and applied solar stove in the largest quantities in the world.

The solar stove can be classified into two types with heat box type and concentrating type. The heat box type solar stove is featured with simple structure, low cost, convenient utilization but is limited in efficiency with moderate temperature which can only be suitable to braise and bake the food in a long time resulting in more utilization limit. Now the concentrating solar stove is broadly applied with the feature of high cooking efficiency, high temperature, short cooking time and strong applicability. In the design of parabolic concentrating solar stove, China proposed the offset axis concentrating and three circularity calculating graphical construction which were innovative and enhanced the design theory of solar stove and increase the its utilization property.
