The fins utilized on the superheater tubes of boilers are pivotal structural components designed to significantly boost heat transfer efficiency. They primarily function to expand the heating surface area, thereby enhancing the rate of heat transfer. Constructed from high-performance metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional resilience against high temperatures and corrosion. This ensures prolonged and stable operation. During the fabrication process of these fins, optimal cost-efficiency and advanced processing technologies are meticulously considered.
The integration of fins effectively addresses the challenge of scaling on the inner walls of boiler superheater tubes. Scaling typically diminishes the heat transfer area of the tube walls, leading to decreased heat transfer efficiency. By employing fins, not only is this issue mitigated, but boiler operating costs are also reduced. This is due to lowered fuel consumption and enhanced boiler efficiency.
Functional characteristics of boiler tube fins:
1. Expand heating area: The inclusion of fins increases the external surface area of the tube, enabling the smoke passing through these fins to transfer heat more efficiently to the internal medium (usually steam). This design significantly enhances the heat transfer capability per unit of volume.
2. Boost heat transfer efficiency: An expanded heating area is directly proportional to a higher heat transfer coefficient, leading to a faster and more effective heat transfer process. This is vital for optimizing boiler efficiency and maintaining precise steam temperature control.
3. Varied structural designs: Fins come in diverse configurations like spiral shapes that continuously encircle the steel pipe and are secured via high-frequency welding. This ensures robustness and minimizes the risk of detachment. Alternatively, separate round sheet shapes are used to address issues such as dust accumulation and dead zones in specific scenarios.
4. Membrane wall applications: In water-cooled wall structures, the utilization of finned tubes is known as a 'membrane wall.' This design not only increases the heating surface but also enhances sealing performance, reduces air leakage in boilers, and boosts overall thermal efficiency.
6. Welding strength and stability: To ensure exceptional quality, finned tubes undergo rigorous welding strength tests, such as pull-out force assessments that must exceed 200MPa. This guarantees the robustness and dependability of the welded joints.
7. Tailored design applications: Double H-shaped finned tubes, thanks to their innovative design, provide superior heating surfaces and improved heat transfer efficiency. They are especially advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, outperforming standard finned tubes.
