The innovative fins employed on the boiler superheater tubes are pivotal structural elements that significantly boost heat transfer efficiency. They are primarily used to magnify the heating area, thereby elevating the rate of heat transfer. Crafted from high-grade metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins possess exceptional resistance to high temperatures and corrosion, ensuring long-lasting and stable operation. In the manufacture of these fins, the balance of cost-effectiveness and advanced processing technology is meticulously considered.
The strategic deployment of fins effectively tackles the challenge of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area of the tube wall, impairing heat transfer efficiency. By utilizing fins, the operating expenses of boilers can be reduced, as they lower fuel consumption while enhancing boiler efficiency, making them an economical choice for sustained performance.
Functional Characteristics of Boiler Tube Fins:
1. Enhanced Heating Area: The fins significantly expand the surface area on the tube's exterior, enabling the smoke traversing between the fins to more efficiently convey heat to the internal medium, typically steam. This innovative design dramatically amplifies heat transfer capacity per unit volume, optimizing energy utilization.
2. Elevated Heat Transfer Efficiency: A larger heating area correlates directly with an increased heat transfer coefficient, facilitating a swifter and more effective heat transfer process. This enhancement is crucial for maintaining optimal boiler efficiency and precise steam temperature control, ensuring performance excellence.
3. Varied Structural Configurations: The fins are available in diverse forms, such as spiral shapes that continuously encircle the steel pipe and are secured with high-frequency welding for enhanced durability. Separate circular sheet forms can also be used, which, despite being subject to single forces, may alleviate issues of dust accumulation and dead zones in certain applications.
4. Membrane Wall Application: When finned tubes are integrated into water-cooled wall structures, they form what is known as a 'membrane wall.' This not only augments the heating surface but also enhances sealing performance, substantially reducing boiler air leakage and boosting overall thermal efficiency.
6. Welding Strength and Stability: High-quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of the welded joints, ensuring enduring performance under demanding conditions.
7. Tailored Design Applications: Exemplified by double H-shaped finned tubes, which, due to their distinctive design, furnish superior heating surfaces and heat transfer efficiency compared to standard finned tubes in various applications such as power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
