The ash-conveying pipeline system of thermal power plants is a key part. Since it involves pneumatic transportation, it faces particularly serious wear problems. Due to the high air pressure, fast flow rate and long-term transportation, as well as the hard particles often contained in the materials, the ash conveying pipeline is prone to wear and tear. This kind of wear will not only cause the leakage of pulverized coal and cause environmental pollution but may also cause safety hazards and waste a lot of materials.
To deal with this problem, many power plants are actively seeking effective solutions. Currently, there are three main solutions commonly available on the market:
1. Reduce the airflow pressure during ash conveying: This method can indeed reduce pipeline wear to a certain extent because it can reduce the material flow rate. However, this often sacrifices ash-conveying efficiency, and the extension of pipeline life is also limited. Therefore, although this method is simple and easy to implement, the effect is not ideal.
2. Patch or make a square box around the pipe: The advantage of this method is that it is simple to operate and low cost. Pipe life can be extended to some extent by reinforcing areas that are worn or likely to wear. However, it can only solve local problems and has a certain lag. When pipes show new wear and tear, they need to be patched again, which increases maintenance costs and workload.
3. Use wear-resistant ceramic pipes: The best way to fundamentally solve the wear problem of ash-conveying pipes is to optimize the pipe material and improve the wear resistance of the pipe itself. Wear-resistant ceramic pipes are an effective solution proven by many thermal power plants. The main component of wear-resistant ceramics is corundum, which has extremely high hardness, far exceeding that of metal. Therefore, wear-resistant ceramic pipes have excellent wear resistance and have a service life far longer than traditional metal pipes.
As a high-quality wear-resistant ceramic pipe manufacturer with 20 years of production experience, the ash-conveying pipes produced by our company are not only affordable but also have strong wear resistance. By using a steel pipe as the outer shell and a wear-resistant ceramic lining as the structural design, the ash conveying pipeline not only ensures strength but also has excellent wear resistance. Its service life is 7-10 times that of metal pipes, providing a strong guarantee for the long-term stable operation of thermal power plants.
