Wear-resistant ceramic liners are best used in power plants


1. Application in ash system

The power plant that uses the hydraulic ash removal slag system, the ash slag pump, the ash slag nozzle, etc. are the most vulnerable parts. According to the field working conditions, it is more suitable to apply the adhesive ceramic.

2. Application in coal transportation system

The wear and tear of the coal handling system equipment is mostly caused by scratches and impacts. The most wearable parts are the falling coal tube, the three-way, the baffle, etc. Generally, the anti-wear methods selected by the power plant include: the use of lining manganese steel plate, this method is not ambition, the reason is that the steel plate is not wear-resistant, the application period is short, And simple sticky coal blockage; bring maintenance work to the maintenance personnel. The use of ultra-high molecular polyethylene sheets, although not easily blocked by coal, but the wear resistance and impact resistance is not as good as the steel plate, especially between the liner and the cylinder wall from the seam into the raw coal, so that the liner bulges and falls. The composite liner of the ceramic liner is embedded in a special rubber by an adhesive ceramic liner, and its wear resistance, impact resistance and inner wall lubrication degree are greatly improved.

3. Application in the milling system

The wear of the coal-making power plant's milling system is dominated by coal dust bumps, conflicts and impacts. The high-speed pulverized coal gas flow is particularly severe for the equipment of the milling system, especially the inlet and outlet pipes of the coal mill outlet pipe, the primary air pipe elbow, and the coarse and fine powder separator. The wear resistance of the cast stone is stronger than that of the ordinary steel plate, but its biggest defect is the brittleness and weight, which is not only restricted by the load safety system of the equipment system, but also easily broken during the installation process. Also, because the thickness of the cast slab is thick and large, the flow cross section of the equipment is reduced, and the flow rate is added, which also exacerbates the degree of wear. Its service life is also difficult to compare with wear-resistant ceramic liners.
