Custom-Fit Casting Boiler Tube Shield for Extreme Temperature Environments

The fins utilized in the boiler superheater tubes are pivotal structural elements specifically designed to drastically enhance heat transfer efficiency. Fundamentally, these fins are employed to enlarge the heating area, thereby significantly boosting the heat transfer rate. Meticulously crafted from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit excellent resistance to high temperatures and corrosion. This robust construction ensures unwavering, long-term stability in operation. During the fin manufacturing process, we meticulously balance cost-effectiveness with advanced processing technology to deliver unparalleled quality.

Employing fins on boiler superheater tubes effectively addresses the critical issue of scaling on the tube’s inner walls. Scaling leads to a reduction in the heat transfer area, consequently diminishing overall heat transfer efficiency. By incorporating fins, we not only mitigate this issue but also significantly reduce boiler operational costs through lowered fuel consumption and enhanced boiler performance.


Functional characteristics of boiler tube fins:
1. Increase heating area: The fins expand the tube's external surface area, allowing the smoke that flows between them to transfer heat more effectively to the medium inside the tube, commonly steam. This innovative design substantially amplifies the heat transfer capacity per unit volume, underscoring its superior efficiency.

2. Improve heat transfer efficiency: The expansion of the heating area directly correlates with an increase in the heat transfer coefficient, ensuring a faster and more efficient heat transfer process. This enhancement is vital for maximizing boiler efficiency and maintaining precise steam temperature control.

3. Diverse structural forms: The fins boast versatile structural designs, such as spiral shapes that continuously encircle the steel pipe, secured by high-frequency welding to ensure durability and resistance to dislodging. Alternatively, they may take the form of separate circular sheets which, despite being subjected to individual forces, effectively minimize dust accumulation and eliminate dead corners in various applications.

4. Membrane wall application: In water-cooled wall structures, the integration of finned tubes is referred to as a 'membrane wall'. This not only amplifies the heating surface but also enhances sealing performance, drastically reduces boiler air leakage, and significantly boosts overall thermal efficiency.

6. Welding strength and stability: Top-tier finned tubes undergo rigorous welding strength assessments, such as pull-out force tests that exceed 200MPa, to guarantee the utmost stability and reliability of the welded joints.

7. Specific design applications: Take, for instance, the double H-shaped finned tubes, whose unique configuration offers superior heating surfaces and heightened heat transfer efficiency compared to standard finned tubes. They are particularly advantageous in power plant boilers, industrial boilers, and systems that recover waste heat from flue gases.
