The innovative fins utilized on boiler superheater tubes serve as a pivotal structural enhancement, strategically designed to boost heat transfer efficiency. Primarily, these fins are employed to expand the heating area, thereby significantly elevating the heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance. This ensures their ability to maintain stable, long-term operation. During the manufacturing process, considerations such as cost-effectiveness and advanced processing technology are meticulously balanced to deliver superior performance.
The strategic application of fins adeptly addresses the challenge of scaling on the inner walls of boiler superheater tubes. Scaling often leads to a reduction in the heat transfer area, consequently diminishing heat transfer efficiency. By incorporating fins, boilers can operate more cost-effectively, as they help minimize fuel consumption and enhance overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Amplified Heating Area: Fins increase the external surface area of the tubes, enabling the smoke flowing between them to transfer heat more effectively to the medium within the tubes, typically steam. This sophisticated design substantially elevates the heat transfer capacity per unit volume.
2. Enhanced Heat Transfer Efficiency: A larger heating area is intrinsically linked with a higher heat transfer coefficient. This crucial correlation ensures that the heat transfer process is rapid and highly effective, vital for optimizing boiler efficiency and precise steam temperature control.
3. Versatile Structural Forms: Fins may be spiral-shaped, enveloping the steel pipe and securely fastened by high-frequency welding, ensuring durability and resistance to detachment. Alternatively, they can be separate circular sheets, which, while subjected to singular forces, may alleviate issues of dust accumulation and dead corners in certain applications.
4. Membrane Wall Application: In water-cooled wall structures, the use of finned tubes results in a 'membrane wall'. This configuration not only augments the heating surface but also enhances sealing performance, reduces boiler air leakage, and boosts overall thermal efficiency.
6. Welding Strength and Stability: Premium quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests that must exceed 200MPa, ensuring the welding joints' stability and reliability.
7. Tailored Design Applications: For instance, double H-shaped finned tubes, with their distinctive design, offer higher heating surfaces and superior heat transfer efficiency compared to standard finned tubes, making them ideal for deployment in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
