The fins used on the boiler superheater tubes serve as a pivotal structural component aimed at elevating heat transfer efficiency. Designed to significantly expand the heating area, these fins enhance the heat transfer rate in a remarkable fashion. Constructed from high-quality materials such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance, ensuring stable long-term performance. In manufacturing, careful consideration is given to cost-effectiveness and processing technology, ensuring both economical and efficient production.
The strategic use of fins effectively addresses the persistent issue of scaling on the inner walls of boiler superheater tubes. Scaling reduces the heat transfer area, leading to diminished heat transfer efficiency. By deploying fins, this challenge is mitigated, resulting in enhanced operational efficiency and reduced fuel costs. The introduction of fins optimizes heat transfer, thereby lowering boiler operating expenses and significantly boosting boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: By expanding the surface area on the tube's exterior, fins allow smoke to flow seamlessly between them, transferring heat more efficiently to the medium inside the tube, typically steam. This innovative design substantially enhances the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An increased heating area correlates directly with a higher heat transfer coefficient. This relationship ensures that the heat transfer process is expedited and highly effective, which is crucial for maximizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse structural forms: Fins can take on various structural forms, such as spirals that continuously encircle the steel pipe, secured by robust high-frequency welding for enhanced durability. Alternatively, fins can be designed as separate circular sheets, which reduce dust accumulation and dead corners, providing versatility for diverse applications.
4. Membrane wall application: In water-cooled wall structures, when finned tubes are employed, they are known as a "membrane wall." This configuration not only augments the heating surface but also improves sealing performance, minimizes boiler air leakage, and significantly boosts overall thermal efficiency.
6. Welding strength and stability: High-quality finned tubes undergo rigorous welding strength tests, such as pull-out force tests exceeding 200MPa, to guarantee the strength and reliability of the welded joints.
7. Specific design applications: The unique design of double H-shaped finned tubes offers superior heating surfaces and enhanced heat transfer efficiency compared to standard finned tubes. This makes them an ideal choice for power plant boilers, industrial boilers, and flue gas waste heat recovery systems, ensuring optimal performance in demanding applications.
