Coal-fired Power Generation In coal-fired power generation, Wodon wear-resistant materials have the following applications: 1. Components of Coal Mills: - Grinding Rolls and Grinding Disks: Coal mills are important equipment in coal-fired power generation, used to grind coal into pulverized coal. During the coal grinding process, the grinding rolls and grinding disks constantly rub and collide with coal, resulting in very severe wear. Wodon wear-resistant materials can be used to manufacture the surface surfacing layers of grinding rolls and grinding disks, improving their wear resistance and impact resistance, and prolonging their service life. Compared to ordinary materials, the grinding rolls and grinding disks surfacing with Wodon wear-resistant materials can withstand harsher working conditions, reduce equipment downtime and maintenance frequency due to wear, and improve the operating efficiency of coal mills. - Linings: The linings inside the coal mills are also subject to the scouring and wear of coal. Wodon wear-resistant linings can be installed inside the cylinder of the coal mill to protect the cylinder from wear. These wear-resistant linings have good wear resistance and impact resistance, can effectively reduce the replacement frequency of linings, and lower maintenance costs. 2. Components of Coal Conveying Systems: - Idlers of Belt Conveyors: In the coal conveying system, belt conveyors are responsible for transporting coal from the coal yard to the coal mill or boiler. Idlers are important components of belt conveyors, supporting the belt and ensuring its normal operation. Due to the weight and friction of coal, idlers are prone to wear. Idlers made of Wodon wear-resistant materials have higher wear resistance and strength, can operate stably for a long time in harsh coal conveying environments, and reduce the replacement and maintenance workload of idlers. - Chutes: During the coal conveying process, coal needs to be transferred and discharged through chutes, and the chutes are subject to significant wear from coal. Wodon wear-resistant materials can be used to manufacture the linings of chutes, increase the wear resistance of chutes, and prevent chutes from being damaged due to wear. Wear-resistant linings can also reduce the clogging of coal in chutes and ensure the smooth operation of the coal conveying system. 3. Components of Boilers: - Burner Nozzles: Burner nozzles are components that inject pulverized coal into the boiler furnace for combustion. The working environment is harsh, and they are subject to scouring and wear from high-temperature and high-speed pulverized coal airflow. Using Wodon wear-resistant materials for surface treatment or manufacturing of burner nozzles can improve the wear resistance and high-temperature resistance of the nozzles, prolong their service life, ensure the normal operation of burners, and improve the combustion efficiency of boilers. - Anti-wear Guard Plates for Water-cooled Wall Tubes: Water-cooled wall tubes are important heat-receiving surfaces of boilers. During the coal combustion process, water-cooled wall tubes are subject to wear from high-temperature flue gas and fly ash. Installing anti-wear guard plates made of Wodon wear-resistant materials on water-cooled wall tubes can effectively protect the water-cooled wall tubes from wear, reduce the risk of leakage of water-cooled wall tubes, and improve the safety and reliability of boilers. 4. Components of Ash and Slag Removal Systems: - Impellers and Shells of Ash and Slag Pumps: In the ash and slag removal system, ash and slag pumps are responsible for transporting ash and slag to designated locations. The impellers and shells are subject to wear and corrosion from ash and slag during the transportation process. Wodon wear-resistant materials can be used to manufacture the impellers and shells of ash and slag pumps, improving their wear resistance and corrosion resistance, prolonging the service life of ash and slag pumps, and reducing the operating costs of the ash and slag removal system. - Elbows and Tees of Pipes: At the elbows and tees of pipes in the ash and slag removal system, the flow velocity of ash and slag changes, causing significant wear on the pipes. Elbows and tees made of Wodon wear-resistant materials have better wear resistance and impact resistance, can reduce the wear and leakage of pipes, and ensure the normal operation of the ash and slag removal system.
