The ingeniously designed fins on boiler superheater tubes are a vital component that significantly enhances heat transfer efficiency. These fins serve to expand the heating area, thereby boosting the heat transfer rate to new heights. Crafted from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, and more, these fins exhibit superior high-temperature and corrosion resistance, ensuring long-lasting, stable operation. During the manufacturing process, both cost-effectiveness and processing technology are meticulously considered, guaranteeing optimal performance.
The strategic use of fins adeptly addresses the issue of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the tube wall's heat transfer area, negatively impacting efficiency. Fins provide an effective solution by maintaining superior heat transfer efficiency, thereby lowering operating costs. By minimizing fuel consumption, these fins remarkably enhance overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The expertly designed fins amplify the surface area outside the tube, allowing smoke to flow between them and transfer heat more effectively to the medium (typically steam) inside the tube. This remarkable design significantly augments the heat transfer capacity per unit volume, making it an essential feature.
2. Improve heat transfer efficiency: With an expanded heating area comes a superior heat transfer coefficient, ensuring a faster and more efficient heat transfer process. This is crucial for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: The fins can adopt various shapes, such as spirals that continuously wrap around the steel pipe and are secured by high-frequency welding for enduring stability. Alternatively, they may be separate circular sheets, effectively mitigating dust accumulation and dead corners in certain applications.
4. Membrane wall application: In water-cooled wall structures, utilizing finned tubes creates a 'membrane wall,' which not only expands the heating surface but also enhances sealing performance. This reduces boiler air leakage and boosts overall thermal efficiency, making it a highly beneficial application.
6. Welding strength and stability: Top-tier finned tubes undergo rigorous welding strength tests, including pull-out force tests exceeding 200MPa, to ensure the welding part's unmatched stability and reliability, thus guaranteeing product excellence.
7. Specific design applications: For instance, double H-shaped finned tubes offer a unique design that provides greater heating surfaces and enhanced heat transfer efficiency compared to ordinary finned tubes, making them indispensable in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
