The fins integrated into the boiler superheater tubes serve as pivotal structural elements that significantly amplify heat transfer efficiency. These components are predominantly designed to augment the heating area, thus elevating the overall heat transfer rate. Crafted from an array of robust metals including 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, the fins exhibit exceptional high-temperature and corrosion resistance. This ensures long-term, stable operation even in the most demanding conditions. During the production of these fins, careful consideration is given to the cost-efficiency and practicality of processing technologies, ensuring a balanced and effective manufacturing process.
The deployment of fins offers a remarkable solution to the challenge of scaling on the inner walls of boiler superheater tubes. Scaling can drastically diminish the heat transfer area of the tube wall, which in turn lowers heat transfer efficiency. By effectively mitigating scaling, fins help maintain optimal heat transfer conditions. Additionally, the integration of fins contributes to reduced operating costs for boilers as they enable lower fuel consumption while significantly enhancing boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: By expanding the surface area on the tube's exterior, the fins facilitate a more efficient transfer of heat from smoke flowing between them to the medium inside the tube (typically steam). This innovative design substantially boosts the heat transfer capacity per unit volume, optimizing performance.
2. Improve heat transfer efficiency: A substantial heating area directly correlates with a superior heat transfer coefficient, indicating a faster and more efficient heat transfer process. This is essential for maximizing boiler efficiency and maintaining precise steam temperature control, ensuring peak operational performance.
3. Diverse structural forms: The fins come in various structural configurations, such as spiral shapes that continuously envelop the steel pipe, secured by high-frequency welding for durability and resistance to detachment. Alternatively, they can be configured as separate circular sheets, which, despite single force application, can minimize issues related to dust accumulation and dead zones in certain applications.
4. Membrane wall application: When finned tubes are employed within water-cooled wall structures, they are referred to as 'membrane walls'. This not only enhances the heating surface but also delivers superior sealing performance, reduces boiler air leakage, and elevates overall thermal efficiency, ensuring optimal energy utilization.
6. Welding strength and stability: Premium-quality finned tubes must undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the welding component's stability and reliability. This rigorous testing ensures long-lasting structural integrity.
7. Specific design applications: For instance, double H-shaped finned tubes, thanks to their distinct design, offer superior heating surfaces and heat transfer efficiency compared to standard finned tubes. They are particularly advantageous for power plant boilers, industrial boilers, and flue gas waste heat recovery systems, delivering exceptional performance in these demanding environments.
