The fins adorning the boiler superheater tubes are pivotal structural components that significantly boost heat transfer efficiency. Primarily utilized to amplify the heating area, they thereby enhance the overall heat transfer rate. Crafted meticulously from premium metals like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast outstanding resistance to high temperatures and corrosion, ensuring prolonged stable performance. During the manufacturing process, both cost rationality and processing technology refinement are prudently considered, ensuring optimal efficiency and effectiveness.
Implementing fins provides a robust solution to the prevalent issue of scaling on the inner walls of boiler superheater tubes. Scaling tends to diminish the heat transfer area of tube walls, lowering heat transfer efficiency. By employing fins, this challenge is effectively addressed, culminating in reduced operational costs for boilers, as they lead to a decrease in fuel consumption and an improvement in boiler efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Augmented Heating Area: Fins expand the exterior surface area of the tube, enabling the smoke flowing amidst the fins to transfer heat more efficiently to the medium within the tube, typically steam. This thoughtful design substantially elevates the heat transfer capability per unit volume.
2. Enhanced Heat Transfer Efficiency: An expanded heating area correlates directly with an increased heat transfer coefficient, signifying a more rapid and effective heat transfer process. This aspect is vital for maintaining optimal boiler efficiency and precise steam temperature control.
3. Versatile Structural Forms: Fins can be intricately spiral-shaped, continuously encircling the steel pipe, secured through high-frequency welding, ensuring robust adherence. Alternatively, they may adopt separate circular sheet forms, which, despite enduring a singular force, can mitigate dust accumulation and dead corners in specific applications.
4. Membrane Wall Application: In water-cooled wall structures, the implementation of finned tubes, termed as "membrane wall," not only amplifies the heating surface but also optimizes sealing performance. This innovation curtails boiler air leakage and elevates overall thermal efficiency, ensuring superior performance.
6. Welding Strength and Stability: High-caliber finned tubes must surpass rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, guaranteeing the stability and reliability of welded joints.
7. Tailored Design Applications: Exemplified by double H-shaped finned tubes, their unique design facilitates greater heating surfaces and heat transfer efficiency compared to conventional finned tubes, especially in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
