Non-ferrous metals are the basic materials for the development of national economy and are widely used in many fields such as aviation, aerospace, automobile, machinery manufacturing, electric power, communication, construction, and home appliances. In recent years, with the vigorous implementation of national environmental protection policy, the non-ferrous industry has actively promoted the upgrading of production technology and equipment, including the heating equipment - industrial boilers.
Different non-ferrous metals have different smelting and rolling processing processes, mainly including the roasting, separation, evaporation and concentration, refining, drying, and crushing processes. What’s more, the sulfuric acid countercurrent washing, slurry neutralization reaction, product synthesis reaction, product washing, product drying, and mother liquor evaporation usually use industrial boilers to ensure the reaction temperature.
ZOZEN gas-fired steam boilers adopt the large-volume furnace which can adapt to a wide range of fuels and ensure the sufficient combustion of fuels. Its boiler thermal efficiency can be further improved with the energy-saving devices at the end of the flue gas duct. Meanwhile, they also have outstanding energy-saving and eco-friendly effects and can realize the ultra-low NOx emissions.
