The innovative fins designed for the boiler superheater tubes are a critical structural component, masterfully crafted to amplify heat transfer efficiency. These fins primarily function to expand the heating area, significantly enhancing the overall heat transfer rate. Engineered from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring unwavering performance over extended periods. During their manufacturing, meticulous attention is given to both cost-effectiveness and the optimization of processing technology, ensuring a perfect balance between quality and affordability.
By integrating fins, a remarkable solution is provided to the prevalent issue of scaling on the inner walls of boiler superheater tubes. Scaling notoriously diminishes the heat transfer surface area, consequently impairing heat transfer efficiency. The clever use of fins not only addresses this challenge but also considerably reduces boiler operating costs. This is achieved by lowering fuel consumption and substantially enhancing overall boiler efficiency, making it a pragmatic choice for modern boiler systems.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins ingeniously augment the external surface area of the tubes, facilitating more efficient heat transfer from the smoke flowing between the fins to the medium within the tube, typically steam. This strategic design dramatically boosts the heat transfer capacity per unit volume, elevating the overall performance.
2. Improve heat transfer efficiency: An expanded heating area directly correlates with an elevated heat transfer coefficient, signifying a swifter and more effective heat transfer process. This enhancement is pivotal for optimizing boiler efficiency and precise steam temperature regulation, ensuring superior operational performance.
3. Diverse structural forms: The versatile fins come in various structural forms, such as spiral shapes that continuously encircle the steel pipe, secured with high-frequency welding for robust and stable attachment. Alternatively, separate circular sheet forms are available, which although subjected to singular forces, can mitigate issues like dust accumulation and dead corners in certain applications, offering tailored solutions.
4. Membrane wall application: When integrated with water-cooled wall structures, finned tubes form what is known as a "membrane wall." This configuration not only considerably increases the heating surface but also enhances sealing performance, significantly reducing boiler air leakage and boosting overall thermal efficiency for optimal energy utilization.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous testing to ensure welding strength and stability. Tests such as pull-out force evaluations, requiring forces greater than 200MPa, are conducted to confirm the robustness and reliability of welded joints, ensuring long-lasting durability.
7. Specific design applications: Notably, double H-shaped finned tubes, defined by their distinctive design, deliver superior heating surfaces and unparalleled heat transfer efficiency. These tubes are particularly advantageous in applications such as power plant boilers, industrial boilers, and flue gas waste heat recovery systems, offering exceptional performance and energy efficiency.
