The fins utilized in the design of boiler superheater tubes serve as a pivotal structural innovation aimed at amplifying heat transfer efficiency. Primarily functioning to expand the heating surface, these fins significantly enhance the rate of heat transfer. Fashioned from durable materials like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these metals boast superior resistance to high temperatures and corrosion, ensuring sustained and reliable operation over extended periods. In the manufacturing process of these fins, careful consideration is given to optimizing costs and processing techniques, ensuring a perfect balance between performance and efficiency.
The strategic use of fins effectively addresses the critical issue of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area of the tube wall, thereby compromising the efficiency of heat transfer. By incorporating fins, this problem is mitigated, leading to enhanced heat transfer efficiency. Furthermore, fins contribute to reduced boiler operating costs by cutting down on fuel consumption and boosting boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increased heating area: The presence of fins dramatically expands the external surface area of the tube. This increased surface area allows the smoke flowing between the fins to transfer heat more effectively to the internal medium, typically steam. As a result, the heat transfer capacity per unit volume is substantially elevated.
2. Enhanced heat transfer efficiency: A larger heating area correlates directly with an escalated heat transfer coefficient. This results in a swifter and more efficient heat transfer process, which is essential for maintaining boiler efficiency and regulating steam temperatures effectively.
3. Versatile structural forms: Fins can adopt various configurations, such as spiral shapes that continuously encircle the steel pipe and are secured by high-frequency welding for a robust, long-lasting hold. Alternatively, they may be separate circular sheets that, despite bearing individual forces, can alleviate issues like dust accumulation and dead zones in specific scenarios.
4. Membrane wall application: In water-cooled wall systems, the incorporation of finned tubes is referred to as a 'membrane wall'. This innovation not only boosts the heating surface but also enhances sealing efficiency, minimizes boiler air leakage, and optimizes overall thermal performance.
6. Welding strength and stability: Premium quality finned tubes must undergo rigorous welding strength evaluations, such as pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of welded components.
7. Special design applications: Double H-shaped finned tubes, thanks to their distinctive design, deliver greater heating surfaces and superior heat transfer efficiency compared to conventional finned tubes. These are especially beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
