The advanced fins integrated into the boiler superheater tubes are innovative structural components meticulously designed to elevate heat transfer efficiency. These fins primarily function to expand the heating area, thereby amplifying the heat transfer rate. Crafted from high-performance metals including 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they exhibit exceptional resistance to high temperature and corrosion. This ensures a prolonged period of stable operation. During the fin manufacturing process, meticulous consideration is given to balancing cost-effectiveness with sophisticated processing technologies.
The strategic implementation of fins offers a robust solution to the scaling challenges on the inner walls of boiler superheater tubes. Scaling is a common issue that diminishes the tube wall's heat transfer area, consequently impairing heat transfer efficiency. By utilizing fins, not only is this issue addressed, but the operating costs of boilers are also significantly reduced. This is achieved through decreased fuel consumption and enhanced boiler efficiency, resulting in substantial operational savings.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins ingeniously extend the surface area surrounding the tube. This allows smoke passing between the fins to transfer heat more effectively to the medium inside the tube, often steam. Such a design significantly boosts the heat transfer capacity per unit volume, ensuring optimal thermal performance.
2. Improve heat transfer efficiency: The expansive heating area directly correlates to a superior heat transfer coefficient, indicating a more rapid and efficient heat transfer process. This enhancement is vital for maintaining high boiler efficiency and precise steam temperature control, which are critical operational parameters.
3. Diverse structural forms: These fins exhibit versatility in their structural forms. They may be spirally shaped, encircling the steel pipe continuously, and are secured with high-frequency welding for robustness and durability. Alternatively, they can be in the form of separate circular sheets, which, while subjected to singular forces, may help mitigate dust accumulation and dead corners in specific applications.
4. Membrane wall application: In water-cooled wall structures, employing finned tubes is referred to as the 'membrane wall.' This application 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: High-quality finned tubes are subjected to rigorous welding strength evaluations, including pull-out force tests that must exceed 200MPa. These tests are crucial to ensure the welding part's stability and reliability, guaranteeing long-lasting performance under demanding conditions.
7. Specific design applications: Noteworthy are the double H-shaped finned tubes, whose distinctive design delivers superior heating surfaces and heat transfer efficiency. They outperform ordinary finned tubes in various applications, including power plant boilers, industrial boilers, and flue gas waste heat recovery systems, thereby driving efficiency and sustainability.
