The innovative fins applied to the boiler superheater tubes are essential structural components that significantly boost heat transfer efficiency. They are meticulously designed to maximize the heating area, thus elevating the heat transfer rate. Crafted from premium-grade metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, guaranteeing long-term, stable operation. Moreover, the process of fin manufacturing takes into account the crucial balance between cost efficiency and processing technology.
Fins are the effective solution to the scaling challenge that plagues the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area of tube walls, adversely impacting heat transfer efficiency. By employing fins, one can not only overcome this issue but also significantly cut down the operational costs of boilers due to reduced fuel consumption and enhanced boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins augment the external surface area of the tube, facilitating the smoke flowing through them to more efficiently transfer heat to the medium inside, typically steam. This design innovation substantially boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expanded heating area correlates with a higher heat transfer coefficient, leading to a more rapid and efficient heat transfer process. This is essential for optimizing boiler efficiency and precise steam temperature regulation.
3. Diverse structural forms: Fins can be configured in spiral shapes encircling the steel pipe, secured by robust high-frequency welding to ensure durability and resistance to detachment. Alternatively, they can be crafted as separate circular sheets, which, while subjected to singular forces, may mitigate challenges like dust accumulation and dead zones in specific scenarios.
4. Membrane wall application: In water-cooled wall structures, the integration of finned tubes, known as "membrane wall", not only amplifies the heating surface but also enhances sealing performance, diminishes boiler air leakage, and elevates overall thermal efficiency.
6. Welding strength and stability: Superior 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 weld joints.
7. Specific design applications: For instance, double H-shaped finned tubes, with their distinctive design, provide a significantly larger heating surface and superior heat transfer efficiency compared to standard finned tubes. They are particularly beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
