The fins incorporated in the boiler superheater tubes are crucial structural components designed to significantly elevate heat transfer efficiency. Primarily, these fins expand the heating area, consequently boosting the heat transfer rate to exceptional levels. Crafted meticulously from premium materials such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit outstanding high-temperature resilience and corrosion resistance. This ensures they remain operationally stable over long periods. During the fin manufacturing process, the company strategically balances cost-effectiveness with advanced processing technologies to deliver superior products.
Fins are ingeniously engineered to address and rectify the common problem of scaling within the inner walls of boiler superheater tubes. Scaling usually diminishes the effective heat transfer area, thus impairing heat transfer efficiency. Through the innovative use of fins, boilers can achieve reduced operational costs by lowering fuel consumption while simultaneously enhancing their efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Increase Heating Area: Boiler tube fins dramatically increase the external surface area of the tubes. This expanded area enables smoke passing through the fins to transfer heat more effectively to the medium inside the tubes, typically steam, markedly enhancing heat transfer capacity per unit volume.
2. Improve Heat Transfer Efficiency: By expanding the heating area, fins establish a direct correlation with a higher heat transfer coefficient. This ensures a quick and efficient heat transfer process, vital for maximizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse Structural Forms: These fins come in a variety of shapes, including spiral forms that continuously encircle the steel pipe, fixed securely by high-frequency welding for robustness and durability. Additionally, separate circular sheet-shaped fins are available, which, despite being subject to singular forces, mitigate issues of dust accumulation and dead corners in specific applications.
4. Membrane Wall Application: In water-cooled wall structures, the inclusion of finned tubes creates 'membrane walls'. This configuration not only amplifies the heating surface area but also enhances sealing performance, significantly curtails boiler air leakage, and boosts overall thermal efficiency.
6. Welding Strength and Stability: Exceptional quality finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa. This guarantees the stability and reliability of the welds, ensuring product longevity and performance consistency.
7. Specific Design Applications: Uniquely designed double H-shaped finned tubes offer superior heating surfaces and enhanced heat transfer efficiency compared to standard finned tubes. These are particularly advantageous in power plant boilers, industrial boilers, and systems for flue gas waste heat recovery, where they significantly optimize performance.
