The fins utilized on boiler superheater tubes serve as a pivotal structural component, meticulously designed to amplify heat transfer efficiency. Their primary function is to broaden the heating area, thereby significantly enhancing the heat transfer rate. Crafted from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring enduring and stable operation. During the manufacturing process, a keen focus is maintained on balancing cost-effectiveness with advanced processing technology.
Fins are ingeniously designed to effectively address the challenge of scaling on the inner walls of boiler superheater tubes, a condition that can diminish the heat transfer area and thus impede efficiency. By incorporating fins, not only is the scaling issue mitigated, but there is also a notable reduction in boiler operating costs. This is achieved through decreased fuel consumption and a marked improvement in overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The adeptly designed fins substantially augment the surface area on the tube's exterior, allowing the smoke traversing between them to transfer heat more efficiently to the internal medium, typically steam. This innovative design significantly boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: By enlarging the heating area, there is a direct enhancement in the heat transfer coefficient, facilitating a swifter and more efficient heat exchange process. This is vital for optimizing boiler efficiency and precise steam temperature management.
3. Diverse structural forms: The fins can be crafted into diverse forms, such as spiral shapes spiraling continuously around the steel pipe, secured by high-frequency welding to ensure durability and resistance to dislodgement. Alternatively, they can be designed as separate circular sheets, minimizing issues like dust accumulation and dead spots in certain applications.
4. Membrane wall application: In water-cooled wall structures, employing finned tubes transforms them into a 'membrane wall'. This not only amplifies the heating surface but also enhances sealing performance, thereby reducing air leakage within the boiler and elevating overall thermal efficiency.
6. Welding strength and stability: Superior quality finned tubes are subjected to rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to guarantee the welding junction's stability and reliability.
7. Specific design applications: Exemplified by the double H-shaped finned tubes, these uniquely engineered designs offer increased heating surfaces and elevated heat transfer efficiency. They prove exceptionally effective in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
