Detailed silicon carbide nozzles

Silicon carbide nozzle is a new ceramic material, it has a high temperature, oxidation, high strength, resistance to extreme cold or heat, thermal shock resistance, high temperature becomes small, good thermal conductivity, wear resistance, corrosion resistance and other characteristics. As energy refractories in sanitary ceramics, porcelain, porcelain, magnetic materials, ceramic stone, powder metallurgy, iron and steel industries such as high-temperature heat treatment furnace is widely used by its various components have gradually made the application in the power generation , paper, petroleum, chemical, mechanical seals, pumps, surface treatment, heat exchange, processing, aerospace and other fields.
Respect for the power plant desulfurization desulfurization nozzle to remove sulfur dioxide in the flue gas power plants, and some polluting gases, coal-fired power plant flue gas and coal-fired combined cycle gas turbine fueled with gas supply have a common task, except that the desulfurization denitration (of course, There are dust). Plant discharged without flue gas desulfurization denitration except direct atmospheric pollution, and combined cycle gas purification treatment will not harm gas turbine hot section. The exhaust will pollute the environment.

Reaction bonded silicon carbide tube has excellent resistance to thermal shock and wear resistance, oxidation resistance, high strength, not slag off, no cracking, long life, easy to replace, is the roller kiln, tunnel kiln, shuttle kiln ideal Spitfire kiln for ceramics, chemicals, glass, metallurgy and other fields to use natural gas, liquefied petroleum gas, diesel and other industrial furnaces with Spitfire mouth, can effectively control the kiln temperature equilibrium.
Some desulfurization equipment, such as slurry pumps, sprinkler pipe, vacuum belt conveyor, top entry agitator, limestone mill, etc., have been localized. However, some key equipment, such as silicon carbide used in the absorber knapsack sprayers nozzles, defogger and side entry mixers and other equipment need to import, the localization rate is very low. Silicon carbide nozzles in the desulfurization unit quantities largest number
Excellent high temperature properties of silicon nitride, silicon carbide products can be used as a binding agent. Silicon nitride bonded silicon carbide products in the last 20 years developed a high-tech silicon carbide material. Its production process is: silicon carbide particles in the mixture, 15% -25% of the fine silica powder, in the high temperature high purity nitrogen gas passed through the furnace to a temperature and pressure curve control nitridation reaction sintering, infiltration of silicon and the nitrogen of the hard carbide combine to form a dense network structure. Therefore, the silicon nitride bonded silicon carbide products with good physical and chemical properties and high temperature performance. Given the characteristics of silicon nitride and silicon carbide materials, desulfurization nozzle materials used are mainly two kinds: 1. Nitride bonded silicon carbide 2 reaction sintered carbide
 Silicon carbide, also known as large flow nozzle vacuum reaction bonded silicon carbide desulfurization nozzle is fired power plants, large boilers, desulphurization and dust removal device sets the key components. Domestic production of reaction-bonded silicon carbide desulfurization dust nozzle, and gradually replace imported products, but also has high strength, high hardness, corrosion resistance strong, severe abrasion,pressure sprayer  high temperature and other excellent performance in harsh conditions with long life.
 Silicon carbide is one of many spiral nozzle nozzle most distinctive species. Becomes smaller as a continuous spiral, helix tangent slurry are continually changing the direction and the collision jet into a sheet-like cone concentric shaft, and the liquid from entering the nozzle chamber to the outlet channel are not subject to any obstacles. And at very low operating pressure still has a high absorption efficiency obtained desulfurization system generally recognized.
