These exceptional fins engineered for boiler superheater tubes are a vital structural component meticulously crafted to amplify heat transfer efficiency. They are primarily employed to expand the heating area, thereby elevating the rate of heat transfer. Fabricated from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit outstanding high-temperature and corrosion resistance, ensuring unwavering, long-term performance. Moreover, during the manufacturing process, both cost-effectiveness and advanced processing technology are meticulously considered to deliver optimal results.
The intelligent design of these fins effectively addresses the challenge of scaling on the inner walls of boiler superheater tubes. Scaling typically diminishes the heat transfer area of the tube wall, leading to reduced heat transfer efficiency. However, with the integration of these fins, scaling issues are significantly mitigated, resulting in enhanced heat transfer efficiency. This, in turn, lowers the operating costs of boilers by minimizing fuel consumption while simultaneously boosting overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: By ingeniously expanding the surface area on the exterior of the tube, the fins facilitate more effective heat transfer from the smoke flowing between them to the medium inside the tube, typically steam. This innovative design dramatically amplifies the heat transfer capacity per unit volume, ensuring heightened efficiency.
2. Improve heat transfer efficiency: The expanded heating area correlates directly to a higher heat transfer coefficient, signifying a more rapid and effective heat transfer process. This enhancement is essential for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: These fins boast versatility with various structural forms. They can be designed in a spiral shape, continuously encircling the steel pipe, and secured with high-frequency welding, ensuring durability and minimal risk of detachment. Alternatively, they can adopt a separate circular sheet form, which, despite bearing individual force, may alleviate dust accumulation and dead corner issues in specific applications.
4. Membrane wall application: In the realm of water-cooled wall structures, the implementation of finned tubes is identified as a 'membrane wall.' This application not only augments the heating surface but also enhances sealing performance, reduces boiler air leakage, and bolsters overall thermal efficiency, leading to exceptional performance.
6. Welding strength and stability: Superior quality finned tubes undergo stringent welding strength evaluations, such as pull-out force tests exceeding 200MPa. These rigorous assessments guarantee the stability and reliability of the welded joints, ensuring exceptional performance under demanding conditions.
7. Specific design applications: Uniquely designed double H-shaped finned tubes offer higher heating surfaces and superior heat transfer efficiency compared to standard finned tubes. They are ideally suited for power plant boilers, industrial boilers, and flue gas waste heat recovery systems, where enhanced performance is crucial.
