The fins, an integral part of boiler superheater tubes, are engineered to elevate heat transfer efficiency, primarily by expanding the heating area, thus significantly enhancing the heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast superior high-temperature and corrosion resistance, ensuring prolonged stable operation. In the manufacturing process, we meticulously balance cost-effectiveness and advanced processing techniques.
Employing fins is a highly effective solution to the scaling issues on the inner walls of boiler superheater tubes, which can diminish the heat transfer area and consequently, the efficiency. By integrating fins, operating costs of boilers can be reduced, as they lead to lower fuel consumption and higher boiler efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Amplified Heating Area: The fins significantly expand the external surface area of the tubes, allowing the smoke traversing the fins to more effectively transfer heat to the medium inside, usually steam. This innovative design markedly boosts the heat transfer capacity per unit volume.
2. Enhanced Heat Transfer Efficiency: The increased heating area correlates directly with a heightened heat transfer coefficient, facilitating a swifter and more efficient heat transfer process, vital for maintaining optimal boiler efficiency and precise steam temperature control.
3. Versatile Structural Designs: Fins can adopt spiral shapes, encircling the steel pipe entirely, secured by high-frequency welding for durability. Alternatively, they can be separate circular sheets, an option that mitigates dust accumulation and eliminates dead corners in various applications.
4. Membrane Wall Utilization: In water-cooled wall structures, the implementation of finned tubes, known as a 'membrane wall', not only augments the heating surface but also enhances sealing, reducing air leakage, and boosting overall thermal efficiency.
6. Welding Strength and Stability: Premium-grade finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, guaranteeing the stability and dependability of the welded joints.
7. Tailored Design Applications: For instance, double H-shaped finned tubes, renowned for their unique design, offer superior heating surfaces and heat transfer efficiency compared to ordinary finned tubes, particularly beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
