The magnesium reduction furnace is the core equipment for magnesium production, and the external heating horizontal reduction tank reduction furnace is widely used at home and abroad. The traditional magnesium reduction furnace generally adopts the structure of reheating the reduction tank.
The new type of magnesium reduction furnace has the following characteristics:
①The regenerative combustion form of diffusion combustion can form a flame type completely different from the traditional flame, forming a particularly uniform temperature field in the furnace, and improving the heating uniformity of the reduction tank.
②The use of low-oxygen combustion technology not only enhances the radiation and convection exchange of the high-temperature flue gas to the reduction tank, but also reduces the erosion and oxidation of the flame to the reduction tank, thereby prolonging the service life of the reduction tank.
③Save energy and reduce fuel consumption. The use of regenerative combustion technology can utilize the waste heat of the flue gas to almost the limit, and maximize the recovery of the latent heat of the flue gas, so that the air and gas can be preheated to be close to the temperature of the furnace gas at the same time, and the exhaust gas temperature can be lower than 150°C. The waste heat recovery rate is greatly improved, and energy saving and consumption reduction are very obvious.
④Improve the heating environment of the reduction tank, form a reducing atmosphere around the reduction tank, reduce the oxidation of the reduction tank, and increase the service life of the reduction tank.
⑤ Reduce environmental pollution. The regenerative combustion technology not only saves energy and reduces the amount of flue gas emissions, but also greatly reduces the content of harmful gases such as NOx in the flue gas and reduces environmental pollution.
⑥High-temperature anti-corrosion (anti-oxidation) and wear-resistant materials are used in the reduction tank to effectively improve the service life of the reduction tank.
⑦Using centralized management and decentralized control, it constitutes a safe, advanced, practical and reliable remote automatic adjustment control system. Reduce a large number of equipment operators.
