The fins utilized in the boiler superheater tubes serve as a crucial structural component designed to significantly enhance heat transfer efficiency. Primarily employed to expand the heating area, these fins play an integral role in improving the overall heat transfer rate. Crafted from high-quality metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature resistance and corrosion resistance, ensuring a stable and long-lasting operation. During the fin manufacturing process, both cost-effectiveness and advanced processing technology are meticulously considered to optimize performance.
Fins are instrumental in effectively resolving the issue of scaling on the inner surfaces of boiler superheater tubes, which can significantly diminish the heat transfer area and consequently reduce heat transfer efficiency. By integrating fins, it is possible to alleviate this problem, minimize fuel consumption, and thus enhance overall boiler efficiency, ultimately lowering operational costs.
Functional characteristics of boiler tube fins:
1. Increased Heating Area: The integration of fins on the tube’s exterior elevates the surface area, facilitating more efficient smoke-to-medium heat transfer, typically involving steam. This strategic design substantially boosts the heat transfer capacity per unit volume, ensuring superior performance.
2. Enhanced Heat Transfer Efficiency: An expanded heating area directly correlates with an increased heat transfer coefficient. This means the heat transfer process is expedited and more effective, which is crucial for maintaining optimal boiler efficiency and precise steam temperature control.
3. Varied Structural Forms: Fins can take on spiral shapes, encircling the steel pipe continuously, and are secured through high-frequency welding for enhanced durability. Alternatively, they can be formed into separate circular sheets, which, while subjected to singular forces, may help in reducing dust buildup and eliminating dead corners in various applications.
4. Membrane Wall Application: In water-cooled wall structures, the application of finned tubes, referred to as a 'membrane wall', not only enhances the heating surface but also provides superior sealing performance. This results in reduced boiler air leakage and an improvement in overall thermal efficiency.
6. Superior Welding Strength and Stability: High-quality finned tubes must undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the welding part's stability and reliability.
7. Tailored Design Applications: For instance, double H-shaped finned tubes, thanks to their unique configuration, deliver higher heating surfaces and heat transfer efficiency compared to standard finned tubes. They are particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
