Spiral Nozzle Silicon carbide spiral nozzles are a distinctive type among many nozzles. As the continuously tapering spiral body guides the slurry, it undergoes tangential and collisional interactions along the spiral path, altering direction to form a sheet-like spray that projects into a concentric conical shape. The liquid encounters no obstructions from the inlet to the outlet of the nozzle cavity. Even at very low operating pressures, it maintains high absorption efficiency, earning widespread recognition in desulfurization systems. Also known as reaction-sintered silicon carbide desulfurization nozzles, these high-flow nozzles are critical components in thermal power plants, large boilers, and integrated desulfurization and dust removal systems. Domestically produced reaction-sintered silicon carbide desulfurization and dust removal nozzles are gradually replacing imported products, offering excellent properties such as high strength, high hardness, resistance to severe corrosion, intense abrasion, and high temperatures, with an extended service life under harsh conditions. Double Hollow Cone Tangential Nozzle Silicon carbide nozzles are a new type of ceramic material characterized by high-temperature resistance, oxidation resistance, high strength, tolerance to extreme thermal cycling, excellent thermal shock resistance, minimal high-temperature deformation, good thermal conductivity, wear resistance, and corrosion resistance. Used in power plant desulfurization, silicon carbide nozzles help remove sulfur dioxide and other pollutants from flue gas. Both coal-fired power plants and integrated gasification combined cycle systems share the common task of desulfurization and denitrification (as well as dust removal). Untreated flue gas emitted from power plants directly pollutes the atmosphere, while untreated gas in combined cycles can damage the hot-end components of gas turbines, and their exhaust also contaminates the environment. Components made from silicon carbide are increasingly used in power generation, papermaking, petroleum, chemical industries, mechanical seals, water pumps, surface treatment, heat exchange, mineral processing, aerospace, and other fields. The double hollow cone tangential nozzle, used within desulfurization towers, features one nozzle spraying upward and another downward, providing uniform spray distribution. It can also be designed with different flow rates for the upper and lower spray holes, such as 80% upward and 20% downward. Hollow Cone Tangential Nozzle Limestone slurry enters the vortex chamber of the nozzle tangentially and is ejected from the orifice at a right angle to the inlet direction. The nozzle is integrally molded by injection, with no internal separation parts. The maximum particle size that can freely pass through the nozzle is approximately 80% of the orifice size, with multiple angle and flow rate options. It boasts high strength, high hardness, resistance to severe corrosion, intense abrasion, and high temperatures, ensuring an extended service life under adverse conditions.
