The fins used on the boiler superheater tubes are a key structural element designed to optimize heat transfer efficiency. These innovative components primarily serve to augment the heating area, thereby significantly enhancing the heat transfer rate. Crafted from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring reliable long-term performance. During the manufacturing process, both cost-effectiveness and processing technology are meticulously considered, ensuring a seamless blend of quality and efficiency.
Fins offer a remarkable solution to the scaling problem that often plagues the inner wall of boiler superheater tubes. Scaling diminishes the heat transfer area, thus impairing efficiency. By incorporating fins, this issue is addressed, leading to enhanced operational efficiency. Notably, fins can substantially decrease boiler operating costs by improving efficiency and reducing fuel consumption, making them an invaluable addition to any boiler system.
Functional characteristics of boiler tube fins:
1. Increase heating area: The ingenious design of fins expands the surface area surrounding the tubes. This allows smoke passing between the fins to transfer heat more efficiently to the medium within the tube, typically steam. As a result, the heat transfer capacity per unit volume is markedly improved, ensuring superior performance.
2. Improve heat transfer efficiency: The enlarged heating area correlates directly with an elevated heat transfer coefficient. This enhancement ensures that the heat transfer process is swift and effective, which is vital for maintaining boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins are available in various structural forms to suit different applications. They can spiral seamlessly around the steel pipe, firmly attached via high-frequency welding to prevent detachment. Alternatively, they can take the form of separate circular sheets, designed to minimize dust accumulation and eliminate potential dead corners in specific settings.
4. Membrane wall application: In water-cooled wall structures, the integration of finned tubes creates a 'membrane wall.' This innovation not only expands the heating surface but also enhances sealing performance, reduces air leakage, and boosts overall thermal efficiency of the boiler system.
6. Welding strength and stability: High-quality finned tubes undergo rigorous welding strength evaluations to ensure durability. Tests such as the pull-out force test, which must exceed 200MPa, are conducted to guarantee the stability and reliability of the welded joints.
7. Specific design applications: The unique design of double H-shaped finned tubes allows them to deliver superior heating surfaces and heat transfer efficiency. These specialized fins outperform ordinary finned tubes, particularly in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, establishing them as the preferred choice for these demanding applications.
