Application of silicon carbide wear parts:sic wear resistant lining in power plant
Application in pulverization system: the abrasion of pulverization system in coal-fired power plant is mainly caused by coal dust collision, friction and impact. The high-speed pulverized coal air flow is particularly severe to the pulverizing system equipment, especially to the coal mill outlet pipeline, the primary air pipeline elbow, the thick and thin powder separator inlet and outlet pipeline. For the power plant to control the powder system to take the method: the application of wear-resisting cement GJ — 199 series, its wear-resisting performance is superior to the steel plate and the strength, adhesion and so on is good.
But its shortcoming is the construction difficulty is bigger and the expense is higher. Cast-stone anti-wear, its wear resistance is stronger than the general steel, but its biggest disadvantage is brittle and weight, not only by the equipment system load safety system restrictions, and easy to break in the installation process. Because of the thick and large volume of the slab, the flow cross section of the equipment is reduced, the flow rate is increased, and the wear is aggravated. Its service life is also difficult compared with the wear-resisting ceramic liner.
Silicon carbide wear parts: SIC wear resistant lining made of silicon carbide is applied. After the use of powder system, it is wear-resistant. The biggest advantage is simple construction and low cost.
