Boiler superheater tubes are enhanced with specialized fins crafted from robust metals like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA. These fins are structural marvels, significantly amplifying heat transfer efficiency by broadening the heating area, ensuring a superior heat transfer rate. With exceptional high-temperature and corrosion resistance, these components promise enduring stability and performance. The manufacturing process skillfully balances cost-efficiency with advanced processing techniques, ensuring a perfect blend of functionality and economy.
Utilizing fins is an ingenious solution to combating scaling on the inner walls of boiler superheater tubes, as scaling diminishes the effective heat transfer area. By optimizing this area, fins not only boost heat transfer efficiency but also trim down operational costs, conserving fuel, and enhancing overall boiler productivity. This innovation ensures a more sustainable and economical approach to boiler operation.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins significantly increase the external surface area of the tubes, thereby optimizing the heat exchange between the flue gases flowing among the fins and the medium inside the tube, typically steam. This meticulous design substantially elevates the heat transfer capability per unit volume, contributing to heightened efficiency.
2. Improve heat transfer efficiency: The expanded heating area correlates with a boosted heat transfer coefficient, ensuring the heat transfer process is both swift and efficient. This is vital for maintaining boiler efficiency and achieving precise steam temperature regulation, pivotal for top-tier performance.
3. Diverse structural forms: Fins exhibit various structural designs, such as spiral configurations encircling the steel pipe, secured with high-frequency welding for durability. Alternatively, they may adopt a separate circular sheet form, which, while single-force-bearing, can mitigate dust accumulation and dead corners, enhancing performance in specific applications.
4. Membrane wall application: In water-cooled wall structures, the adoption of finned tubes creates a 'membrane wall,' which not only expands the heating surface but also enhances sealing efficiency. This design reduces boiler air leakage, thereby boosting overall thermal efficiency and ensuring superior performance.
6. Welding strength and stability: Premium finned tubes undergo rigorous welding strength evaluations, such as pull-out force tests exceeding 200MPa, to guarantee the welding joint's stability and reliability. This ensures the durability and trustworthiness of the entire assembly.
7. Specific design applications: Unique designs like double H-shaped finned tubes offer expanded heating surfaces and amplified heat transfer efficiency, making them ideal for power plant boilers, industrial boilers, and systems recovering waste heat from flue gases. Their advanced design outperforms conventional finned tubes by leaps and bounds, illustrating cutting-edge innovation in thermal management.
