The fins employed on boiler superheater tubes serve as a pivotal structural enhancement to boost heat transfer efficiency. These components are indispensable for expanding the heating surface area, thereby elevating the heat transfer rate. Crafted from robust materials like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance, ensuring long-lasting, stable operation. During their manufacture, careful consideration is given to both cost-effectiveness and processing technology to optimize performance and economic viability.
Integrating fins significantly addresses scaling issues on the inner walls of boiler superheater tubes. Scaling is known to diminish the heat transfer area, thus impeding efficiency. By incorporating fins, not only is the heat transfer efficiency fortified, but operational costs are also reduced by conserving fuel and enhancing boiler performance.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins augment the external surface area of the tubes. This expansion allows the smoke traversing the fins to transfer heat more effectively to the medium inside the tubes, typically steam. This innovative design profoundly boosts heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: Enlarging the heating area directly elevates the heat transfer coefficient, making the heat transfer process swifter and more efficient. This enhancement is vital for ensuring optimal boiler efficiency and precision in steam temperature management.
3. Diverse structural forms: Fins can adopt a spiral shape, wrapping continuously around the steel pipes, secured by high-frequency welding for durability. They can also take the form of separate circular sheets, which, despite bearing a singular force, may mitigate dust accumulation and dead corners in certain applications.
4. Membrane wall application: Utilization of finned tubes in water-cooled wall structures is termed as 'membrane wall'. This approach not only amplifies the heating surface but also enhances sealing performance, curtails boiler air leakage, and elevates the overall thermal efficiency.
6. Welding strength and stability: High-caliber finned tubes undergo rigorous welding strength evaluations, such as the necessity for pull-out force tests to exceed 200MPa, to assure the welding joints' stability and reliability.
7. Specific design applications: Exhibiting unique designs, such as double H-shaped finned tubes, these can deliver superior heating surfaces and heat transfer efficiency compared to conventional finned tubes, especially in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
