The fins used on the boiler superheater tubes are a critical structural component engineered to significantly enhance heat transfer efficiency. They are specifically designed to increase the heating area, thus amplifying the heat transfer rate. These fins, crafted from high-grade metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, exhibit exceptional high-temperature and corrosion resistance, ensuring prolonged and stable operation over time. In the manufacturing process, we prioritize cost efficiency and advanced processing technology to deliver unparalleled performance.
The incorporation of fins effectively addresses the issue of scaling on the inner walls of boiler superheater tubes. Scaling often diminishes the heat transfer area of the tube wall, leading to a drop in heat transfer efficiency. By utilizing fins, we can also significantly reduce the operational costs of boilers, as they minimize fuel consumption while elevating boiler efficiency to impressive levels.
Functional characteristics of boiler tube fins:
1. Increase heating area: The innovative design of fins expands the exterior surface area of the tube, enabling the smoke navigating through the fins to transfer heat more effectively to the medium inside the tube—typically steam. This design remarkably boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expansive heating area is intrinsically linked to a higher heat transfer coefficient, which ensures a swifter and more efficient heat transfer process. This enhancement is vital for maintaining boiler efficiency and precise steam temperature management.
3. Diverse structural forms: The versatile fins can be spiral-shaped, continuously encircling the steel pipe and secured by robust high-frequency welding, ensuring durability and stability. Alternatively, they may take the form of separate circular sheets, which can mitigate issues like dust accumulation and dead corners in certain applications.
4. Membrane wall application: In water-cooled wall configurations, employing finned tubes results in a 'membrane wall' structure. This not only augments the heating surface but also enhances sealing performance, curtails boiler air leakage, and optimizes overall thermal efficiency.
6. Welding strength and stability: High-quality finned tubes must undergo rigorous testing to meet stringent welding strength criteria, such as pull-out force tests exceeding 200MPa, ensuring the stability and reliability of the welded joints.
7. Specific design applications: Unique designs like double H-shaped finned tubes provide superior heating surfaces and elevated heat transfer efficiency compared to conventional finned tubes. These are particularly beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
