The advanced fins used on boiler superheater tubes are critical structural enhancements designed to dramatically boost heat transfer efficiency. Primarily, these fins serve to expand the heating surface area, thereby significantly elevating the heat transfer rate. Crafted from high-performance metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional resistance to high temperatures and corrosion, ensuring prolonged, stable performance. During production, a strategic balance between cost-efficiency and processing technology is carefully maintained to optimize results.
Introducing fins into boiler systems effectively addresses the challenge of scaling on the inner walls of superheater tubes, a common issue that can diminish the heat transfer surface area and, consequently, the efficiency of heat transfer. By integrating fins, operational costs of boilers can be significantly reduced through lowered fuel consumption and heightened boiler efficiency.
Functional characteristics of boiler tube fins:
1. Enhanced heating area: The fins substantially amplify the external surface area of the tube, enabling smoke to more efficiently conduct heat to the tube's internal medium, typically steam, thereby significantly boosting heat transfer capacity per unit volume.
2. Elevated heat transfer efficiency: The expanded heating area correlates directly with an increased heat transfer coefficient, facilitating a swifter and more effective heat transfer process, vital for maintaining optimal boiler efficiency and precise steam temperature regulation.
3. Versatile structural designs: Fins may adopt a spiral form, encircling the steel pipe with high-frequency welding for robust attachment, minimizing detachment risks. Alternatively, separate circular sheet fins can be employed, potentially alleviating dust buildup and mitigating dead zones in certain applications.
4. Membrane wall application: In water-cooled wall structures, the use of finned tubes, known as a 'membrane wall,' not only augments the heating surface but also enhances sealing performance, curtailing boiler air leakage and substantially boosting overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to certify the stability and dependability of the welds.
7. Tailored design applications: Notably, double H-shaped finned tubes, due to their distinctive design, offer superior heating surfaces and heat transfer efficiency compared to conventional finned tubes, particularly in power plant boilers, industrial boilers, and systems for recovering waste heat from flue gas.
