Pneumatic ash conveying technology, as the core ash removal method in power plants, chemical plants, and other industries, is of self-evident importance. However, with the increasingly stringent environmental protection and safety standards, and the increase in ash conveying volume due to improved production efficiency, ash conveying pipelines face many challenges. So, what are these challenges specifically? How should we deal with them?
Pipeline wear problem
Pneumatic ash conveying pipelines are prone to fatigue wear and erosion wear under high-speed, large-flow airflow and dust scouring, and in severe cases, they may even cause pipeline wear. This will not only reduce the conveying efficiency but also cause gas leakage and dust pollution, bringing great inconvenience and safety hazards to production.
Countermeasures: To address this problem, we can choose to use high-hardness, strong wear-resistant pipeline materials or linings. For example, wear-resistant ceramic pipes are an ideal choice. This kind of pipe can effectively resist the scouring of airflow and dust, reduce wear, and increase the service life of the pipe.
Difficulties and maintenance costs of high-altitude operations
Due to space and site limitations, many pneumatic ash conveying pipelines are erected at high altitudes. However, the high density and heavy weight of metal pipes bring great difficulties to high-altitude operations and increase maintenance costs. Once the pipes have problems such as wear, maintenance work will become extremely difficult.
Coping strategy: If the installation position of the pipe cannot be changed, we can consider using pipe materials with lower density and lighter weight. Alumina wear-resistant ceramic pipes are a good example. Its density is only half that of metals such as steel, which can significantly reduce the difficulty of high-altitude operations and reduce labor costs. In addition, this type of pipe also has strong wear resistance, which can extend service life and reduce maintenance costs.
In summary, by using high-performance materials such as wear-resistant ceramic pneumatic ash conveying pipes, we can effectively cope with the challenges faced by pneumatic ash conveying pipes. This type of pipe can not only improve wear resistance and extend service life, but also reduce the difficulty of installation and maintenance, providing strong guarantees for the production of power plants, chemical plants, and other industries.
