In the world of advanced heat exchange technology, the fins utilized on boiler superheater tubes stand as a crucial structural element significantly boosting heat transfer efficiency. These fins are engineered to expand the heating surface, thereby dramatically improving the rate of heat transfer. Crafted from high-grade metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they boast excellent resistance to high temperatures and corrosion, ensuring prolonged and stable performance. In the manufacturing process, a keen eye is maintained on cost-effectiveness and innovative processing technology, balancing quality with economic efficiency.
Fins present a practical solution to the recurring issue of scaling on the inner walls of boiler superheater tubes, which otherwise diminishes the heat transfer area and efficiency. The strategic use of fins not only curtails scaling but also slashes operating costs by reducing fuel consumption and elevating overall boiler efficiency, making them indispensable in modern boiler operations.
Functional characteristics of boiler tube fins:
1. Increase Heating Area: Fins ingeniously augment the exterior surface area of the tubes, enabling the smoke that flows between them to transfer heat more effectively to the medium inside (commonly steam). This innovative design significantly enhances the heat transfer capacity per unit of volume, revolutionizing thermal efficiency.
2. Improve Heat Transfer Efficiency: The expansion of heating area correlates directly with a heightened heat transfer coefficient, ensuring a swifter and more efficient heat exchange process. This is pivotal for optimizing boiler efficacy and maintaining precise steam temperature control.
3. Diverse Structural Forms: Fins are available in various configurations, such as spiral shapes that envelop the steel pipe continuously, affixed securely by high-frequency welding to prevent dislodgement. Alternatively, separate circular sheet designs are available, which can alleviate issues related to dust accumulation and dead corners in specific applications.
4. Membrane Wall Application: In water-cooled wall frameworks, employing finned tubes transforms the structure into a 'membrane wall.' This setup not only amplifies the heating surface but also enhances sealing performance, mitigates air leakage in boilers, and boosts overall thermal efficiency.
6. Welding Strength and Stability: High-caliber finned tubes must undergo rigorous welding strength evaluations, such as pull-out force tests exceeding 200MPa, to ensure robust stability and unyielding reliability of the welded joints.
7. Specific Design Applications: Special designs like double H-shaped finned tubes offer superior heating surfaces and augmented heat transfer efficiency. These are particularly effective in power plant boilers, industrial boilers, and systems for recovering waste heat from flue gases, far surpassing the performance of standard finned tubes.
