The Structural Design and Analysis of Melting Aluminium Furnace for Flue Gas Circulation

Zhang Jia'nan | Chen Bo

Abstract: It is the common problem for the intense energy dissipation of melting aluminium furnace. It is the biggest heat waste in ordinary combustion to discharge the flue gas to the atmosphere. Therefore, to design a new type of external device for melting aluminum furnace, will cycle the flue gas back to the melting aluminum furnace to participate in the combustion, and reuse the heat energy. In the condition of the absence of heat balance test, the smelting process is divided into several time node, using MATLAB software to heat balance calculation by iteration, so that it is getting the fuel consumption. In the result, it shows that compared with ordinary combustion, using this way can save fuel by 43.6 %, and its combustion efficiency is 38.57 %, and can maintain the stability of temperature of the furnace. The structure of the device and the calculation method of energy savings can be utilizedto reference in the research and the designersin enterprise.
