It is understood that Yan Yanjun is the director of the village-town Ronghua Ceramic Heat Exchanger Plant. He usually likes to study innovative ceramic products and has made unremitting efforts to establish a relationship with ceramics. The ceramic heat exchanger he invented recently has proved to be a direct and simple method of use. Quick and other advantages, the heat exchange principle is: the use of waste heat from the furnace flue gas outlet, the original cold air used in the furnace, through the heat exchanger into hot air into the furnace, improve efficiency, save a lot of energy .
According to the data, the ceramic heat exchanger is the national torch plan and is the designated product of the outline of China's energy conservation technology policy. It was identified by the Henan Institute of Science and Technology Information and used cordierite-mullite, silicon carbide, ceramic metal materials and processes. Ceramic heat exchangers are the first case in the country.
A farmer in Henan Province successfully developed a ceramic heat exchanger
Recently, the porcelain heat exchangers and ceramic materials successfully developed by the peasant Yan Yanjun of Dongshe Village, Gongshe Village, Gongyi City, Henan Province, and the production methods thereof have obtained the invention patent certificates issued by the State Intellectual Property Office.
