The state-of-the-art fins utilized on the boiler superheater tubes are essential structural components meticulously engineered to amplify heat transfer efficiency. Primarily, they serve to expand the heating area, thus significantly boosting the rate of heat transfer. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance. Such attributes ensure the enduring and stable operation of your systems. During the manufacturing process, we keenly consider both the cost-effectiveness and the sophistication of processing technologies.
The strategic implementation of fins is pivotal in effectively addressing scaling issues on the inner walls of boiler superheater tubes—a common problem that curtails the heat transfer area and, consequently, diminishes efficiency. By employing fins, we enhance the boiler's operational efficiency and drastically curtail fuel consumption, achieving a harmonious balance between performance and cost management.
Functional characteristics of boiler tube fins:
1. Increase heating area: The extended surface area offered by the fins on the tube exterior permits the smoke flowing between them to more proficiently convey heat to the medium within the tube, typically steam. This innovative design significantly magnifies the heat transfer capacity for each unit of volume, optimizing performance.
2. Improve heat transfer efficiency: The expanded heating area is intrinsically linked to an elevated heat transfer coefficient, indicating a swift and efficacious heat transfer process. This enhancement is crucial for maximizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse structural forms: The fins can be designed in spiral shapes, continuously encircling the steel pipe, and are secured by high-frequency welding to ensure durability and prevent detachment. Alternatively, they can be configured as separate circular sheets, which, despite enduring singular forces, may mitigate dust accumulation and eliminate dead corners in particular applications.
4. Membrane wall application: When employed in water-cooled wall structures, finned tubes are referred to as the 'membrane wall'. This application not only amplifies the heating surface but also enhances sealing performance, reduces air leakage, and bolsters the overall thermal efficiency of boilers.
6. Welding strength and stability: Premium finned tubes undergo rigorous welding strength evaluations, such as pull-out force examinations exceeding 200MPa, ensuring unmatched stability and reliability of the welded joints.
7. Specific design applications: Double H-shaped finned tubes, for instance, present a unique design offering superior heating surfaces and enhanced heat transfer efficiency compared to conventional finned tubes. These are particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
