On October 26, Fang Dachan received a patent authorization from the China National Intellectual Property Administration，the Company《A New Type of Ring Furnace Gas Burner》obtaining utility model patents.
       In carbon industry production, the heating method of the roasting ring furnace is achieved by igniting gas through the burner, which has been granted a utility model patent. At present, there are two air supply methods for gas burners: forced air supply and natural air supply. Forced air supply is the process of introducing compressed air into the burner, mixing compressed air and gas in a certain proportion before combustion. When the compressed air pressure is too high during use, local combustion may lead to cooling, which makes it difficult to control the pressure range of the mixed compressed air. Sometimes, it is necessary to repeatedly adjust the ratio to achieve the combustion effect. Natural air supply does not require compressed air, but relies on the negative pressure formed in the furnace to suck air into the burner, mix it with gas, and then burn it. The burner with natural air supply has a simple structure, convenient control, and low maintenance, making it widely used in carbon production ring furnaces. However, this type of burner produces direct injection combustion after mixing air and gas, and the mixing effect of air and gas is average. How to better improve the degree of air and gas mixing and improve combustion efficiency is an urgent technical problem that needs to be solved in existing technologies. A New Type of Ring Furnace Gas Burner provides a new type of ring furnace gas burner, which achieves more complete combustion after natural mixing and rotation of air and gas. The flame is spiral shaped, with strong combustion and long flame injection length. This device has a simple structure, convenient installation and operation, low cost, and improves combustion efficiency, which has practical value for promotion. (Kang Xiu leads Li Tianxiu)
