The coal powder transportation system of thermal power plants consists of three main links: raw coal storage, grinding, and powder transportation. Due to the continuous scouring and wear of coal powder particles on the pipeline during transportation, traditional metal pipelines are often unable to withstand such harsh working environments and are prone to wear and perforation, resulting in coal powder leakage, which not only affects power generation efficiency but also may bring safety hazards.
In order to solve this problem, we recommend the use of composite pipes made of wear-resistant ceramic materials. By closely embedding wear-resistant ceramic sheets or ceramic tubes on the inner wall of the pipeline, a solid wear-resistant protective layer is formed to effectively resist the erosion of coal powder particles.
The hardness of wear-resistant ceramic materials is extremely high, with a Rockwell hardness of more than 88HRA and a Mohs hardness of 9. The wear resistance is more than ten times that of ordinary high-chromium cast iron. In addition, alumina ceramics also have excellent corrosion resistance and can cope with a variety of corrosive media including strong acids and strong alkalis. Therefore, they are widely used in chemical, metallurgical, steel, cement, and other industries.
The use of alumina ceramic composite pipes can significantly improve the wear resistance of the power plant's pulverized coal conveying system, extend the service life of the equipment to more than 5 years, and ensure the stable operation and safety of the power plant.
