The fins utilized in the boiler superheater tubes are ingeniously designed structural components that significantly enhance the efficiency of heat transfer. Primarily serving to expand the heating area, these fins substantially elevate the heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they exhibit remarkable high-temperature and corrosion resistance. This ensures a prolonged and stable operational lifespan. During the manufacturing process, careful consideration is also given to cost-effectiveness and processing technology, ensuring a balanced approach.
The strategic use of fins effectively addresses the challenge of scaling on the inner walls of boiler superheater tubes. Scaling often reduces the heat transfer area, leading to decreased efficiency. By employing fins, this issue is mitigated, optimizing the heat transfer process. Additionally, fins contribute to reduced operational costs by lowering fuel consumption and enhancing overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Expanded heating area: Fins augment the external surface area of the tubes, enabling the smoke passing between them to transfer heat more effectively to the medium inside, typically steam. This innovative design substantially boosts heat transfer capacity per unit volume, enhancing overall performance.
2. Enhanced heat transfer efficiency: The increased heating area directly correlates with a heightened heat transfer coefficient. This implies a faster and more efficient heat exchange process, critically supporting boiler efficiency and precise steam temperature regulation.
3. Versatile structural designs: Fins are available in various configurations. They can be spiral, continuously encircling the steel pipe and securely attached through high-frequency welding, ensuring durability. Alternatively, fins can be designed as individual circular sheets, which may alleviate dust accumulation and minimize dead corners in certain applications.
4. Membrane wall application: In water-cooled wall structures, the integration of finned tubes, known as a 'membrane wall', amplifies the heating surface and delivers superior sealing performance. This reduces boiler air leakage, thereby boosting overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength evaluations, such as pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of the welded joints.
7. Specialized design applications: For instance, double H-shaped finned tubes, owing to their unique configuration, deliver higher heating surfaces and enhanced heat transfer efficiency compared to conventional finned tubes. These are extensively used in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
