The fins incorporated into the boiler superheater tubes are ingeniously crafted structural elements that significantly enhance heat transfer efficiency. They primarily serve to expand the heating area, thereby markedly boosting the heat transfer rate. Crafted from premium metals including 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit excellent high-temperature and corrosion resistance, ensuring reliable, long-term performance. Our meticulous manufacturing process also considers the cost-effectiveness and technical feasibility to deliver a product that balances efficiency and economic viability.
Employing fins is a brilliant solution to the persistent challenge of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area, thus hampering heat transfer efficiency. Fins adeptly counteract this by maximizing the heating surface area, which consequently lowers operating costs by reducing fuel consumption and amplifying boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins ingeniously expand the surface area on the tube's exterior, enabling smoke to more efficiently convey heat to the medium inside, typically steam. This innovative design substantially elevates the heat transfer capacity per unit volume, optimizing energy usage.
2. Improve heat transfer efficiency: The expanded heating area directly correlates with a heightened heat transfer coefficient. This enhancement accelerates the heat transfer process, which is vital for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins are available in versatile shapes, such as spirals enveloping the steel pipe, which are securely affixed via high-frequency welding for durability. Alternatively, they can be separate circular sheets to mitigate dust buildup and dead corners in select applications, ensuring adaptability across varying operational needs.
4. Membrane wall application: In water-cooled wall configurations, the use of finned tubes, known as 'membrane walls', not only enlarges the heating surface but also enhances sealing performance. This reduces air leakage in boilers and significantly boosts overall thermal efficiency, making it an exceptional choice for modern applications.
6. Welding strength and stability: Premium finned tubes are subjected to rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee unwavering stability and reliability in the weld areas, assuring users of their enduring dependability.
7. Specific design applications: Specialized designs, such as double H-shaped finned tubes, offer superior heating surfaces and enhanced heat transfer efficiency compared to conventional finned tubes, particularly in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, setting new standards in energy efficiency.
