The finely engineered fins employed on boiler superheater tubes serve as a critical structural component designed to amplify heat transfer efficiency. Primarily, these fins expand the heating surface, thereby significantly boosting the rate of heat transfer. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional resilience to high temperatures and corrosion. This ensures a prolonged, stable operational lifespan. During manufacturing, a balanced approach is adopted, considering both cost-effectiveness and processing technological advancements.
The strategic implementation of fins adeptly addresses the prevalent issue of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the available heat transfer surface of the tube walls, thereby impairing efficiency. By integrating fins, not only is this challenge mitigated, but the operational costs of the boilers are also reduced. This is achieved through minimized fuel consumption and enhanced overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: By expanding the external surface area of the tube, fins optimize the pathway for smoke flow between them, which facilitates a more effective transfer of heat to the medium within the tube (primarily steam). This strategic design markedly boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: The enlarged heating area directly correlates with an elevated heat transfer coefficient. This translates to a more swift and efficient heat transfer process, playing a pivotal role in maintaining optimal boiler efficiency as well as precise steam temperature regulation.
3. Diverse structural forms: Fins can assume various configurations, such as a spiral formation that continuously encircles the steel pipe, secured by high-frequency welding. This robust design is resistant to detachment. Alternatively, fins may adopt a separate circular sheet form, which, while subjected to a singular force, can mitigate issues of dust accumulation and dead zones in certain applications.
4. Membrane wall application: When integrated into water-cooled wall structures, finned tubes transform into what is known as a 'membrane wall'. This integration not only enhances the heating surface but also ensures superior sealing capabilities, significantly reducing air leakage and elevating the overall thermal efficiency of the boiler.
6. Welding strength and stability: Premium finned tubes are subjected to rigorous tests to ascertain welding strength, including the pull-out force test where the threshold exceeds 200MPa. This is crucial for maintaining the stability and reliability of the welded joints.
7. Specific design applications: Double H-shaped finned tubes, with their distinctive configuration, deliver superior heating surfaces and heat transfer efficiency compared to conventional finned tubes. These are particularly beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, offering unparalleled performance.
