The innovative fins incorporated into the boiler superheater tubes are a crucial structural component designed to significantly enhance heat transfer efficiency. These ingenious fins primarily function to expand the heating area, thereby substantially boosting the heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature endurance and corrosion resistance, ensuring the boiler's long-term stable performance. During the fin manufacturing process, careful consideration is given to both cost-effectiveness and advanced processing technology to deliver optimal results.
Utilizing these expertly engineered fins effectively addresses the challenge of scaling on the interior walls of boiler superheater tubes. Scaling can significantly decrease the heat transfer area, leading to reduced heat transfer efficiency. By integrating fins, not only is the heat transfer efficiency enhanced, but there is also a notable reduction in boiler operating costs. This is achieved through decreased fuel consumption and improved overall efficiency of the boiler.
Functional characteristics of boiler tube fins:
1. Increase heating area: Ingeniously designed, the fins expand the external surface area of the tube, allowing the smoke that flows between the fins to transfer heat more effectively to the medium inside the tube, typically steam. This smart design dramatically amplifies the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: With a significantly enlarged heating area, the result is a higher heat transfer coefficient. This translates to a faster, more effective heat transfer process, which is pivotal for optimizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse structural forms: The fins boast a variety of structural forms. They can be spirally shaped, continuously wrapping around the steel pipe and secured by high-frequency welding for firm attachment, minimizing the risk of detachment. Alternatively, they can be individually circular, which, despite bearing a singular force, may help to lessen dust accumulation and prevent dead corners in certain applications.
4. Membrane wall application: In water-cooled wall structures, the use of finned tubes is recognized as a 'membrane wall'. This application not only amplifies the heating surface but also enhances sealing performance, significantly reducing boiler air leakage and elevating overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa. These stringent tests ensure the weld's stability and reliability, providing peace of mind in performance.
7. Specific design applications: For instance, double H-shaped finned tubes, thanks to their unique design, offer superior heating surfaces and heightened heat transfer efficiency compared to standard finned tubes. These advancements are particularly beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
