Background
The secondary aluminum is aluminum alloy or aluminum metal obtained by remelting and refining waste aluminum and waste aluminum alloy materials or aluminum-containing waste materials, and is an important source of metal aluminum. Secondary aluminum is mainly present in the form of aluminum alloys. The main raw materials for smelting the secondary aluminum are industrial depreciated waste aluminum parts (such as airplane waste parts and engines, case covers and the like) and waste aluminum materials (including plates, pipes, bars, sections, scraps, foils and the like) generated in the aluminum processing process.
The dispersion combustion (also called high-temperature low-oxygen combustion or high-temperature air combustion) is different from the traditional combustion mode of diffusion type and premixing type flames, and has a series of advantages of high thermal efficiency, low pollutant discharge amount and the like. It is generally accepted that one of the necessary conditions for the dispersion combustion to take place is to preheat the combustion air to very high temperatures (about 800 to 1000 c).
