The fins utilized on boiler superheater tubes represent a paramount structural innovation aimed at amplifying heat transfer efficiency. These fins primarily function by expanding the heating area, thus substantially enhancing the heat transfer rate. Crafted from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional resistance to high temperatures and corrosion, ensuring prolonged and reliable operation. During their manufacture, we meticulously balance the cost-effectiveness with advanced processing technology to achieve the pinnacle of performance and durability.
Finned technology offers an ingenious solution to the prevalent issue of scaling inside the walls of boiler superheater tubes, which typically diminishes the heat transfer area, thereby lowering efficiency. With the introduction of fins, not only is the heat transfer area restored, but the overall operating costs of boilers can be significantly reduced. This is achieved through decreased fuel consumption and enhanced boiler efficiency, delivering optimal performance and energy savings.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins dramatically expand the surface area of the tube exterior, facilitating more effective heat transfer from the smoke flowing between the fins to the medium within the tube, typically steam. This cutting-edge design substantially boosts heat transfer capacity on a per-unit-volume basis.
2. Improve heat transfer efficiency: By offering a larger heating area, fins contribute to a higher heat transfer coefficient, ensuring a faster and more efficient heat exchange process. This is essential for maintaining high boiler efficiency and precise steam temperature control, meeting the rigorous demands of modern industrial applications.
3. Diverse structural forms: Fins can be spirally shaped, enveloping the steel pipe with steadfast high-frequency welding, ensuring durability and stability. Alternatively, they may be fashioned as separate circular sheets, offering advantages in certain applications by minimizing dust accumulation and reducing dead zones.
4. Membrane wall application: In water-cooled wall configurations, the use of finned tubes is referred to as a 'membrane wall.' This not only augments the heating surface but also enhances sealing performance, significantly reducing boiler air leakage and maximizing thermal efficiency.
6. Welding strength and stability: High-caliber finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to guarantee the stability and dependability of welded joints, ensuring they meet exacting industry standards.
7. Specific design applications: For instance, double H-shaped finned tubes, owing to their unique geometry, deliver superior heating surfaces and heightened heat transfer efficiency compared to conventional finned tubes, making them ideal for power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
