The cutting-edge fins used on our boiler superheater tubes serve as an integral structural component designed to amplify heat transfer efficiency. Their primary function is to expand the heating area, thereby significantly boosting the heat transfer rate. Constructed from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, these fins provide exceptional high-temperature and corrosion resistance, ensuring extended, stable operations. Our fin manufacturing process meticulously balances cost-effectiveness with advanced processing technology.
Implementing fins effectively addresses issues related to scaling on the inner walls of boiler superheater tubes. Scaling can diminish the heat transfer area, thus lowering heat transfer efficiency. Fins not only mitigate this issue but also contribute to reduced operational costs by lowering fuel usage and enhancing overall boiler efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Expand Heating Area: The strategically engineered fins enlarge the tube's exterior surface area, facilitating more effective heat transfer from smoke flowing between the fins to the medium inside (commonly steam). This design substantially upgrades the heat transfer capacity per unit volume.
2. Enhance Heat Transfer Efficiency: A greater heating area correlates directly with an elevated heat transfer coefficient, leading to a more rapid and efficient heat transfer process. This enhancement is crucial for maximizing boiler performance and precise steam temperature regulation.
3. Versatile Structural Forms: Fins can be crafted in spirals, continuously enveloping the steel pipe and secured using high-frequency welding for robustness and durability. Alternatively, they can be formed as discrete circular sheets, which may reduce dust buildup and dead corners in some applications.
4. Membrane Wall Application: Employed in water-cooled wall structures, finned tubes form a 'membrane wall,' augmenting the heating surface and providing superior sealing capabilities. This innovative design reduces air leakage in boilers, thereby improving overall thermal efficiency.
6. Welding Strength and Stability: Premium finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the welds' stability and reliability.
7. Specialized Design Applications: Unique double H-shaped finned tubes cater to specific needs, offering superior heating surfaces and heat transfer efficiency over standard fins, particularly in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
