The innovative fins utilized on boiler superheater tubes are an essential structural component meticulously designed to significantly boost heat transfer efficiency. Primarily, these fins serve to expand the heating area, thereby elevating the heat transfer rate to remarkable levels. Crafted with precision from metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring prolonged and stable operation. During the manufacturing process, a keen focus is placed on optimizing both cost-effectiveness and advanced processing technology.
The strategic implementation of these fins provides a proficient solution to the scaling issue often encountered on the inner walls of boiler superheater tubes. Scaling diminishes the tube wall's heat transfer area, thus compromising heat transfer efficiency. By employing fins, this challenge is overcome, reducing boiler operating costs through decreased fuel consumption and heightened efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The intelligent design of fins enhances the external surface area of the tube. This allows the passing smoke to transfer its heat more efficiently to the medium inside (commonly steam), significantly amplifying the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: Enhanced surface area directly correlates to a superior heat transfer coefficient, indicating a more rapid and effective heat transfer process. This is vital for maximizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse structural forms: These fins come in various configurations, such as spiral shapes that continuously encircle the steel pipe, secured by robust high-frequency welding to ensure durability. Alternatively, separate circular sheet forms may be utilized to potentially mitigate dust accumulation and eliminate dead corners in certain applications.
4. Membrane wall application: In water-cooled wall structures, integrating finned tubes results in what's known as a "membrane wall." This innovation not only expands the heating surface but also enhances sealing performance, curtails boiler air leakage, and bolsters overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength evaluations, including pull-out force tests that must exceed 200MPa, guaranteeing the welding part's stability and reliability.
7. Specific design applications: Finned tubes, particularly the double H-shaped variants, offer a unique design that delivers superior heating surfaces and heat transfer efficiency over conventional finned tubes. This is especially advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
