The fins utilized on the boiler superheater tubes are a pivotal structural innovation designed to significantly boost heat transfer efficiency. They chiefly serve to expand the heating area, thereby elevating the heat transfer rate remarkably. Crafted from high-performance metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring steadfast long-term performance. In the manufacturing process, careful consideration is given to cost efficiency and advanced processing technologies to maintain optimal quality and performance.
Utilizing fins effectively addresses the scaling issue on the inner walls of boiler superheater tubes, which can otherwise diminish the heat transfer area and impair efficiency. The strategic deployment of fins not only enhances heat transfer efficiency but also contributes to considerable operational cost savings by reducing fuel consumption, thus boosting overall boiler performance and efficacy.
Functional Characteristics of Boiler Tube Fins:
1. Augmented Heating Area: The fins ingeniously expand the external surface area of the tube, facilitating more efficient heat transfer from the smoke flowing between the fins to the medium within the tube, typically steam. This innovative design substantially amplifies the heat transfer capacity per unit volume.
2. Enhanced Heat Transfer Efficiency: By enlarging the heating area, the fins directly contribute to a superior heat transfer coefficient. This results in a swifter and more effective heat transfer process, which is crucial for maintaining optimal boiler efficiency and precise steam temperature control.
3. Versatile Structural Forms: The fins are available in diverse configurations, such as spiral shapes that continuously encircle the steel pipe and are secured via high-frequency welding for enhanced durability. Alternatively, circular sheet forms minimize issues like dust accumulation and dead corners in certain applications, despite being subject to a singular force.
4. Membrane Wall Application: In water-cooled wall structures, the use of finned tubes is termed a "membrane wall." This application not only augments the heating surface but also substantially enhances sealing performance, reduces air leakage, and boosts overall thermal efficiency of the boiler.
6. Welding Strength and Stability: Finned tubes of superior quality must endure rigorous welding strength evaluations, such as pull-out force tests that exceed 200MPa, to guarantee the stability and reliability of the welded joints.
7. Specialized Design Applications: Unique designs like double H-shaped finned tubes offer enhanced heating surfaces and superior heat transfer efficiency compared to standard finned tubes. They are particularly beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems where maximizing efficiency is paramount.
