The fins employed on boiler superheater tubes are an innovative structural component crafted to significantly boost heat transfer efficiency. These fins primarily serve to expand the heating surface area, thereby enhancing the heat transfer rate. Constructed from superior materials like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, the fins exhibit remarkable high-temperature tolerance and corrosion resistance, ensuring robust and sustained performance over time. The design and manufacture of these fins are strategically optimized, balancing cost-effectiveness with advanced processing technologies.
The integration of fins adeptly addresses the challenge of scaling on the inner walls of boiler superheater tubes. Scaling can impede the heat transfer efficiency by reducing the available surface area. Fins mitigate this issue, enhancing heat transfer efficiency and, in doing so, contribute to lowering the operational costs of boilers by minimizing fuel consumption and maximizing overall efficiency.
Functional characteristics of boiler tube fins:
1. Expanded Heating Area: The innovative fin design increases the external surface area of the tubes. This allows the smoke flowing between the fins to transfer heat more effectively to the medium inside (commonly steam), remarkably enhancing heat transfer capability per unit volume.
2. Enhanced Heat Transfer Efficiency: A substantially enlarged heating area correlates with a superior heat transfer coefficient, facilitating a swift and efficient heat transfer process, which is vital for maintaining optimal boiler efficiency and precise steam temperature control.
3. Versatile Structural Designs: Fins can be crafted into various shapes, such as a spiral structure that continuously wraps around the steel pipe, secured by high-frequency welding for durability. Alternatively, they can be individual circular sheets, which may help mitigate dust accumulation and eliminate dead corners in certain applications.
4. Membrane Wall Integration: When finned tubes are utilized in water-cooled wall structures, forming a 'membrane wall,' they not only expand the heating surface but also enhance sealing performance. This reduces boiler air leakage and significantly boosts overall thermal efficiency.
6. Robust Welding Strength and Stability: Premium quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to guarantee the stability and dependability of the welding connections.
7. Specialized Design Applications: For instance, double H-shaped finned tubes, with their unique design, deliver superior heating surfaces and enhanced heat transfer efficiency, outperforming conventional finned tubes in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
