Regenerative combustion technology can maximize the recovery of flue gas waste heat during the smelting process of aluminum melting furnaces, improve the thermal efficiency of the furnace, reduce pollutant emissions, and reduce energy consumption. Since the British company developed the first single regenerative burner in 1982, this technology has developed rapidly. It has been widely used in various types of furnaces and has very broad prospects.

Regenerative combustion technology enables combustion at low oxygen concentrations. The high-temperature flue gas after the reaction is used to preheat the air to a temperature of 800~1000°C, and is sprayed into the furnace at a certain speed to mix with the combustion products in the furnace. This is different from traditional combustion methods. The traditional combustion method requires air with an oxygen concentration of more than 20% to react with material to obtain kinetic energy.

Regenerative combustion technology has a wide range of applications. It is suitable for both new aluminum melting furnaces and the regenerative technological transformation of old aluminum melting furnaces. It can keep the original furnace foundation and steel structure unchanged, and add regenerative burners on both sides or the same side of the furnace. It is simple to construct and has advanced technology. Mature. And this technology is suitable for various fuels such as light oil, heavy oil, coal tar, mixed gas, etc., especially for mixed gas with low calorific value, it has a good preheating and combustion-supporting effect. The regenerative burner burns alternately, and the high-temperature flue gas circulates rapidly in the furnace, which is beneficial to improving the melting effect of the aluminum melt, speeding up the aluminum speed, and achieving greater hourly melting capacity. The aluminum melting furnace adopts regenerative combustion technology, which can achieve good results.
