The pulverized coal conveying pipes of the boilers of thermal power plants are wear-resistant and must be designed for leak-proof, anti-corrosion, rain-proof, anti-freezing and other factors. The key points are anti-wear and anti-corrosion. It has always been the key part of power plant maintenance. The comprehensive performance of the pipeline system, especially the wear resistance, is directly related to the operating cost and economic benefit of the entire power plant, and is a key issue that must be considered in the construction and maintenance of new power plants.
In response to the above situation, we have summarized the use of pulverized coal pipeline wear-resistant elbows in thermal power plants over the years, and absorbed the advanced experience of the international industry. Considering the convenience of construction, low manufacturing cost and relatively simple manufacturing process, the following mainstream wear-resistant types of pulverized coal pipeline wear-resistant elbows are recommended:
1)Wear-resistant ceramic tiles lined composite bend
2)High chrome alloy bimetal bend
3)Silicon carbide tube lined composite bend
