Desulfurization of spray nozzle is the key components of a large power plant absorption tower, boiler, steel sintering desulfurization desulfurization dusting of complete sets of equipment. The Material has reaction sintered silicon carbide and stainless steel 316 l, etc. SISIC desulfurization nozzle has the advantages of high strength, high hardness, strong corrosion resistance, high wear resistance, high temperature resistance and other excellent properties . The desulfurization nozzle,of our company has good spray droplet distribution is uniform, smooth flow channel, no blocking phenomenon. At present, there are many kinds of spiral solid cone type, vortex hollow cone type, vortex solid cone type, liquid column type and so on.
