The innovative fins integrated into the boiler superheater tubes are engineered as a crucial structural component, meticulously designed to amplify heat transfer efficiency. Primarily, these fins serve to expand the heating area, thus significantly boosting the rate of heat transfer. Crafted from high-quality metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit excellent resistance to high temperatures and corrosion. This ensures their capability to maintain long-term, stable operations. During the manufacturing process, a balanced approach to cost-effectiveness and processing technology is meticulously considered to optimize performance and value.
The strategic application of fins ingeniously addresses the challenge of scaling on the inner wall of boiler superheater tubes. Scaling can detrimentally reduce the heat transfer area of the tube wall, thereby diminishing heat transfer efficiency. By implementing fins, this issue is effectively mitigated, leading to enhanced heat transfer efficiency. Additionally, the incorporation of fins contributes to a reduction in boiler operation costs by decreasing fuel consumption and optimizing overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins ingeniously expand the surface area on the tube's exterior, enabling the smoke flowing amidst the fins to efficiently transfer heat to the medium inside the tube, typically steam. This advanced design substantially augments the heat transfer capacity for each unit of volume, offering unparalleled performance benefits.
2. Improve heat transfer efficiency: A significantly enlarged heating area correlates directly with a heightened heat transfer coefficient. This ensures that the heat transfer process is exceptionally rapid and effective, which is paramount for maintaining optimal boiler efficiency and precise steam temperature control, crucially enhancing system performance.
3. Diverse structural forms: The fins are available in various innovative structural forms, such as spiral shapes that continuously wrap around the steel pipe. They are securely affixed using high-frequency welding, ensuring robustness and resistance to detachment. Alternatively, the fins can be configured as separate circular sheets, which may mitigate issues of dust accumulation and dead corners in select applications.
4. Membrane wall application: In water-cooled wall structures, the integration of finned tubes results in a configuration known as a "membrane wall". This not only expands the heating surface but also offers superior sealing performance, reducing boiler air leakage and significantly enhancing overall thermal efficiency for a more effective operation.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength tests, including pull-out force tests that exceed 200MPa. This ensures that the welding connections are stable and reliable, underpinning the structural integrity and longevity of the fins in demanding operational environments.
7. Specific design applications: For instance, double H-shaped finned tubes boast a unique design that provides notably higher heating surfaces and heat transfer efficiency compared to standard finned tubes. These are particularly advantageous in applications such as power plant boilers, industrial boilers, and flue gas waste heat recovery systems, where exceptional heat management is critical.
