The fins utilized on the boiler superheater tubes are an essential structural component meticulously engineered to amplify heat transfer efficiency. These fins are predominantly employed to significantly bolster the heating area, thereby enhancing the overall heat transfer rate. Crafted from a selection of high-caliber metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast remarkable high-temperature and corrosion resistance, ensuring the enduring stability and reliable operation of the system. During the manufacturing process, we carefully balance cost efficiency and advanced processing technology to deliver optimal performance.
Implementing fins offers a highly effective solution to the persisting issue of scaling on the interior walls of boiler superheater tubes. Scaling can detrimentally diminish the heat transfer area of the tube walls, thereby impairing heat transfer efficiency. The strategic use of fins not only mitigates this issue but also slashes the operational costs of boilers by substantially reducing fuel consumption while enhancing boiler efficacy.
Functional characteristics of boiler tube fins:
1. Increase heating area: The innovative design of the fins amplifies the surface area on the tube's exterior, allowing the smoke traversing between the fins to transfer heat more effectively to the medium within the tube (typically steam). This design approach significantly elevates the heat transfer capacity per unit volume, optimizing performance.
2. Improve heat transfer efficiency: An expanded heating area is directly linked to an elevated heat transfer coefficient, facilitating a more rapid and efficient heat transfer process. This is paramount in ensuring boiler efficiency and precise steam temperature regulation.
3. Diverse structural forms: Fins can be ingeniously designed in spiral forms, encircling the steel pipe continuously, and securely affixed via high-frequency welding for durability and resistance to detachment. Alternatively, fins may be structured as discrete circular sheets, which, despite being subjected to singular forces, can mitigate dust accumulation and dead corner issues in certain scenarios.
4. Membrane wall application: When integrated into water-cooled wall structures, finned tubes are referred to as 'membrane walls'. This application not only augments the heating surface but also enhances sealing performance, curtails boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: Premium-grade finned tubes undergo rigorous welding strength evaluations, including pull-out force tests exceeding 200MPa, ensuring the stability and reliability of the welded joints. This rigorous testing guarantees the longevity and dependability of the product.
7. Specific design applications: Notably, double H-shaped finned tubes, acclaimed for their distinctive design, provide superior heating surfaces and heat transfer efficiency compared to standard finned tubes. Their application is ideal for power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
