The innovative fins used on the boiler superheater tubes are crucial structural components designed to significantly enhance heat transfer efficiency. They are primarily utilized to expand the heating surface area, thereby optimizing the heat transfer rate. Crafted from high-performance materials such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast excellent high-temperature durability and superior corrosion resistance, ensuring consistent and reliable long-term operation. During fin manufacturing, a meticulous balance of cost-effectiveness and superior processing technology is carefully considered.
The implementation of fins is an effective solution to combat scaling issues on the inner walls of boiler superheater tubes. Scaling can drastically reduce the heat transfer area, thereby diminishing heat transfer efficiency. By employing fins, boilers can operate more cost-effectively, as they enhance efficiency, leading to reduced fuel consumption and improved overall performance.
Functional characteristics of boiler tube fins:
1. Enhance Heating Area: Fins significantly increase the external surface area of the tubes, allowing the smoke flowing between them to efficiently transfer heat to the contained medium, typically steam. This design innovation dramatically elevates the heat transfer capacity per unit volume.
2. Elevate Heat Transfer Efficiency: An expanded heating area correlates directly with a heightened heat transfer coefficient, facilitating a quicker, more effective heat transfer process. This is paramount in maintaining optimal boiler efficiency and precise steam temperature regulation.
3. Versatile Structural Forms: The fins can be crafted in spiral shapes, continuously encircling the steel pipe and secured via high-frequency welding for robust attachment. Alternatively, they may be designed as separate circular sheets, which, despite bearing individual forces, can mitigate dust accumulation and eliminate dead zones in select applications.
4. Membrane Wall Application: When incorporated into water-cooled wall structures, finned tubes become part of what is known as a 'membrane wall.' This integration not only amplifies the heating surface but also enhances sealing performance, curtails boiler air leakage, and boosts overall thermal efficiency.
6. Welding Strength and Stability: To guarantee the stability and reliability of the high-quality finned tubes, they must undergo stringent welding strength assessments, like pull-out force tests which must exceed 200MPa.
7. Specialized Design Applications: Exemplified by double H-shaped finned tubes, their distinctive design offers superior heating surfaces and improved heat transfer efficiency over conventional finned tubes. This is particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
