The innovative fins incorporated into the boiler superheater tubes are a pivotal component designed to significantly boost heat transfer efficiency. Primarily employed to augment the heating surface area, these fins substantially enhance the heat transfer rate. Crafted from prestigious metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, and others, these fins boast exceptional high-temperature and corrosion resistance. This ensures enduring, stable performance over long durations. When producing these fins, the cost-effectiveness and sophistication of the processing technology are diligently evaluated to offer superior performance.
Integrating fins is an effective strategy to address the scaling issue on the internal walls of boiler superheater tubes. Scaling typically diminishes the tube wall's heat transfer area, thereby compromising efficiency. With the application of fins, boilers enjoy reduced operational costs due to diminished fuel consumption, alongside improved efficiency. Thus, fins not only maintain but elevate the performance of boilers.
Functional characteristics of boiler tube fins:
1. Expand heating area: The inclusion of fins significantly enlarges the surface area on the tube's exterior, enabling the smoke flowing between them to efficiently deliver heat to the medium within, commonly steam. This engineering marvel considerably amplifies the heat transfer capacity within a given volume, maximizing thermal performance.
2. Elevate heat transfer efficiency: A larger heating surface correlates with a heightened heat transfer coefficient, accelerating the heat exchange process. This feature is paramount for achieving optimum boiler operation and precise steam temperature regulation, ensuring efficiency is always at its peak.
3. Versatile structural designs: Fins may take on a spiral shape, securely enveloping the steel pipe through robust high-frequency welding, ensuring steadfastness and resistance to detachment. Alternatively, they may exist as individual circular sheets, which, while subjected to a singular force, may alleviate dust buildup and minimize dead corner issues in select scenarios.
4. Membrane wall application: In water-cooled wall designs, the adoption of finned tubes is often referred to as a 'membrane wall.' This approach not only enlarges the heating surface but also enhances sealing efficiency, curtails boiler air leakage, and bolsters overall thermal efficiency, leading to superior operational effectiveness.
6. Welding strength and stability: Premium-quality finned tubes are subjected to rigorous welding strength assessments, including pull-out force tests exceeding 200MPa. This ensures the welds' stability and reliability, guaranteeing long-lasting structural integrity under demanding conditions.
7. Tailored design applications: Double H-shaped finned tubes, for example, offer an extraordinary design that provides increased heating surfaces and enhanced heat transfer efficiency. These are particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, surpassing the performance of standard finned tubes.
