[0002] Boiler steam pipes are important piping systems used to transport high-temperature and high-pressure steam generated by boilers. They transport steam from boilers to various industrial equipment (such as steam turbines and heaters) or heating systems. The pipes are usually made of high-temperature and high-pressure resistant materials, and are equipped with valves and brackets to ensure flow control and safety support. Due to the high temperature and high pressure involved, the design and maintenance of steam pipes must follow strict safety standards to prevent leakage, corrosion or overpressure accidents, and ensure the efficient and stable operation of the system. The purpose of predicting the scale generation rate of boiler steam pipes is to improve the safety of the system, extend the service life of the equipment, and optimize operational efficiency. The formation of scale may cause pipeline corrosion, reduce heat transfer efficiency, and cause safety hazards. Therefore, by predicting its generation rate, operators can take maintenance and cleaning measures in time to prevent sudden failures and reduce economic losses. In addition, understanding the dynamics of scale generation also helps to select appropriate materials and design pipelines to ensure the durability and economy of the system.
