The fins employed on the boiler superheater tubes are pivotal structural elements that significantly boost heat transfer efficiency. By amplifying the heating area, they enhance the overall heat transfer rate. Crafted from premium metals like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature resistance and corrosion protection, ensuring steadfast performance over time. During manufacturing, meticulous attention is given to both cost-effectiveness and processing technologies to secure optimal outcomes.
Fins are an ingenious solution to address the scaling issue on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area, thereby impairing efficiency. By incorporating fins, this challenge is effectively mitigated, resulting in reduced boiler operational costs through decreased fuel usage and enhanced overall boiler efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Increase Heating Area: Fins significantly expand the tube's external surface area, allowing the smoke interflowing between them to transfer heat more effectively to the medium inside, typically steam. This advanced design substantially boosts heat transfer capacity per unit volume.
2. Improve Heat Transfer Efficiency: A larger heating area correlates with a superior heat transfer coefficient, facilitating a faster and more efficient heat transfer process. This efficiency is paramount for maximizing boiler performance and achieving precise steam temperature control.
3. Diverse Structural Forms: Fins can take on various configurations, such as spiral shapes that encircle the steel pipe, secured by robust high-frequency welding to prevent detachment. Alternatively, they may be individual circular sheets, which, while subject to singular forces, can help minimize dust accumulation and eliminate dead zones in specific applications.
4. Membrane Wall Application: In water-cooled wall infrastructures, the use of finned tubes is referred to as a "membrane wall." This not only augments the heating surface area but also enhances sealing performance, curtailing air leakage in boilers and boosting overall thermal efficiency.
6. Welding Strength and Stability: Premium-quality finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the welding's steadfastness and dependability.
7. Specific Design Applications: For example, double H-shaped finned tubes boast a unique configuration that delivers superior heating surfaces and heat transfer efficiency compared to standard finned tubes. This innovation is instrumental in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, where efficiency is paramount.
