The fins used on the boiler's superheater tubes are an advanced structural innovation that significantly enhances heat transfer efficiency. These high-performance fins are crucial in expanding the heating area, thereby substantially boosting the heat transfer rate. Crafted from top-tier metals like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they exhibit remarkable high-temperature endurance and corrosion resistance, ensuring long-term stability in tough operational conditions. The production of these fins also incorporates a balanced consideration of cost-effectiveness and sophisticated processing technology.
Innovatively designed fins offer an effective solution to the common issue of scaling on the inner walls of boiler superheater tubes. Scaling can seriously impair the heat transfer capacity by diminishing the heat transfer area. By adopting fins, not only is this problem mitigated, but the overall operational cost of boilers is also reduced. The employment of fins leads to lowered fuel consumption and heightened boiler efficiency, creating an economically and environmentally beneficial heating solution.
Functional characteristics of boiler tube fins:
1. Increase heating area: By increasing the surface area on the tube's exterior, the fins allow smoke flowing between them to transfer heat more efficiently to the medium inside (primarily steam). This strategic design significantly amplifies the heat transfer capacity per unit volume, leading to superior performance.
2. Improve heat transfer efficiency: The amplified heating area correlates directly to a heightened heat transfer coefficient. This enhancement ensures a faster and more effective heat transfer process, which is absolutely essential for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins are available in versatile structures, including spiral shapes that continuously wrap around the steel pipe, secured firmly by high-frequency welding to prevent detachment. Alternatively, they may be separate circular sheets, which, while subjected to single force, reduce dust accumulation and eliminate dead corners in specific scenarios.
4. Membrane wall application: In water-cooled wall configurations, the utilization of finned tubes creates what is known as a 'membrane wall.' This application not only expands the heating surface but also enhances sealing performance, drastically minimizing boiler air leakage and boosting overall thermal efficiency.
6. Welding strength and stability: Premium-grade finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the utmost stability and reliability of the welded sections, ensuring safe and efficient operation.
7. Specific design applications: Exemplifying specific designs, double H-shaped finned tubes offer superior heating surfaces and unparalleled heat transfer efficiency. These advanced designs prove exceptionally beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, outperforming standard finned tubes.
