Reaction bonded silicon carbide nozzle for desulfurization is an indispensable element in large power plant absorption tower, boiler, steel sintering, desulfurization dusting and other complete sets of equipment. It features good spray droplet distribution, smooth flow channel and no blocking phenomenon.
Sintered silicon carbide is an extremely durable ceramic material, capable of withstanding high temperatures and pressures without succumbing to corrosion, making it an excellent choice for chemical processing applications.
Spiral Nozzle
Silicon carbide (SiC) stands out among industrial materials as an example of resilience and efficiency, frequently being utilized in high-stakes applications due to its durability, resistance to wear, and impressive performance under challenging conditions. It has earned itself an exceptional reputation.
SiC, an innovative combination of silicon and carbon, offers superior strength, remarkable hardness, chemical inertness, extreme temperature resistance and exceptional lightweight strength – making it the ideal material for various industrial applications including the production of durable nozzles for flue gas desulfurization and denitrification processes.
Spiral nozzles are widely utilized across industries including desulphurization, dust removal, exhaust gas processing, fireproofing, spraying cleaning and firefighting. Their compact designs ensure clear flow paths to allow fluids to move freely within any size pipeline without blockages and interruption. Available with full cone patterns or hollow configurations they make excellent tools.
BETE’s spiral nozzle design makes it possible to avoid clogging. By eliminating the need for separate guide and blade systems that could become blocked up over time, our spiral nozzles feature larger inlet to outlet passageways that reduce potential blockages. Furthermore, BETE specializes in custom fabrication that optimizes spray processes.
Swirl Nozzle
Reaction bonded silicon carbide (SiC) is an industrial ceramic with great strength, hardness, abrasion resistance, operating temperature resistance, corrosion resistance and rapid cooling properties. Suitable applications for SiC include power desulfurization systems as nozzles or structural parts as well as various industrial uses like heat resistance or wear resistance.
These nozzles typically made from durable material with smaller and more uniform internal flow channels than in traditional desulfurization systems, providing for greater atomization of gas while being less likely to jam or jamming altogether. Furthermore, their durable nature helps protect them against erosion while keeping their shape.
Research studies have investigated the effect of structural parameters of nozzles on spray characteristics. One such investigation concluded that an ideal combination for optimal atomization performance included expansion section angle of 30 deg, length of straight section of 4mm and contraction section angle of 45deg. In another research project analyzing open-end swirl nozzle liquid film thickness measurement parameters included expansion section angle 30 deg, straight section diameter 4mm and contraction section angle 45deg as optimal parameters.
Hollow Cone Nozzle
The hollow cone nozzle employs a tangential flow design where liquid is introduced at an acute angle into the nozzle, producing centrifugal force which creates an outer perimeter spray pattern around its edge and also known as hydraulic atomization – producing some of the finest droplets achievable from pressure-operated designs.
The BETE TH series hollow-cone spray nozzle features a durable one-piece casting that offers an unobstructed passageway, making it clog resistant. Its geometry offers uniform spray distribution at low flow rates for a range of fluids and applications such as cooling, washing, gas scrubbing/cooling/dust control. This device makes an ideal addition to your arsenal!
Silicon Carbide is an ideal material for high temperature abrasion applications due to its hardness, strength, wear resistance and corrosion resistance. Furthermore, its low thermal expansion rate and resistance to chemical attack make it suitable for harsh environments – often used in furniture for tunnel, shuttle and roller kilns as well as thermocouple protection tubes.
Reaction sintered silicon carbide (RSiC) ceramic offers low coefficient of expansion, is highly abrasion resistant, and can be polished down to near zero RMA RA values – qualities which make it suitable for many high temperature applications, including gas and steam turbines, furnace doors/components and other metallurgical equipment.
Solid Cone Nozzle
Solid cone series of nozzles are well suited for spray applications that cover an isolated area, providing uniform spray distribution with medium to large droplet size over a wide range of flow rates and pressures. Furthermore, these can also be used at lower pressures without compromising their spray quality or performance.
These nozzles feature a ring-shaped impact area and large unobstructed flow passages to prevent clogging, providing even and consistent distribution over a large area at low to moderate flow rates, helping ensure effective atomization. This type of nozzle is perfect for cooling, washing, gas scrubbing / cleaning and dust control applications.
Reaction sintered silicon carbide has many advantages over other ceramic materials for use in nozzles, including its superior bending strength, wear resistance and corrosion resistance. Furthermore, its thermal conductivity and low thermal expansion rates make it suitable for many industrial applications.
Reaction bonded silicon carbide nozzles are used frequently in power plant flue gas desulfurization systems to filter out pollutants like sulfur dioxide from steam. If they aren’t removed efficiently, these pollutants could harm thermal end parts of gas turbines as well as pollute the environment, so regular maintenance of the nozzles must take place so they continue to function optimally.
