The fins used on the boiler superheater tubes are an integral structural component engineered to significantly enhance heat transfer efficiency. They are primarily utilized to expand the heating area, thereby optimizing the heat transfer rate. Crafted from high-performance metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance, ensuring long-term stable operation even under the most demanding conditions. Considerations of cost-effectiveness and advanced processing technology are key factors during the fin manufacturing process.
The incorporation of fins offers an effective solution to the scaling issues on the inner walls of boiler superheater tubes. Scaling can diminish the heat transfer area of the tube walls, consequently impacting heat transfer efficiency. By integrating fins, we can significantly reduce the operational costs of boilers, as fins contribute to decreased fuel consumption and markedly improved boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins substantially enlarge the surface area on the tube's exterior, enabling the smoke that flows between them to transfer heat more effectively to the medium inside the tube, typically steam. This design innovation significantly boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expanded heating area directly correlates with an increased heat transfer coefficient, indicating a more rapid and efficient heat transfer process. This aspect is crucial for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: The fins are available in various structural forms, such as spiral shapes that continuously envelop the steel pipe, secured by robust high-frequency welding to prevent detachment. Alternatively, they can be fashioned as separate circular sheets, which, while subjected to individual forces, may help minimize dust accumulation and eliminate dead corners in specific applications.
4. Membrane wall application: In water-cooled wall structures, the use of finned tubes is termed a "membrane wall." This not only augments the heating surface but also offers superior sealing performance, reduces boiler air leakage, and enhances overall thermal efficiency.
6. Welding strength and stability: High-quality finned tubes are required to undergo rigorous welding strength tests, such as pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of the welded joints.
7. Specific design applications: For instance, the double H-shaped finned tubes, owing to their distinctive design, deliver higher heating surfaces and heat transfer efficiency compared to standard finned tubes. These are particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
