The highly engineered fins employed on boiler superheater tubes serve as pivotal structural components that dramatically enhance thermal conductivity. Their primary role is to augment the heating surface area, thereby significantly boosting the heat transfer rate. Crafted from robust materials such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, and others, these fins exhibit excellent high-temperature resistance and anti-corrosion properties, ensuring long-lasting stable performance. During fin production, cost-effectiveness and advanced processing techniques are meticulously balanced to optimize performance.
Fins present an ingenious solution to the pervasive issue of scaling on the inner walls of boiler superheater tubes, a condition that undermines heat transfer due to reduced surface area. By utilizing fins, the operational costs associated with boilers are effectively curtailed, as they substantially lower fuel consumption while simultaneously elevating overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: By expanding the external surface area of the tube, fins enable the smoke interacting with the fins to more efficiently convey heat to the medium inside (typically steam). This innovative design significantly amplifies the heat transfer capacity per unit volume, thus optimizing performance.
2. Improve heat transfer efficiency: The direct correlation between an expansive heating area and a heightened heat transfer coefficient ensures the heat transfer process is remarkably swift and effective. This capability is vital in safeguarding boiler efficiency and precise steam temperature regulation.
3. Diverse structural forms: Fins can adopt various innovative shapes, such as spirals that encircle the steel pipe, secured through robust high-frequency welding, minimizing the risk of detachment. Alternatively, fins may take the form of discrete circular sheets, which can mitigate dust accumulation and eliminate dead corners in specific applications.
4. Membrane wall application: In water-cooled wall frameworks, the use of finned tubes, known as 'membrane walls,' not only expands the heating surface but also enhances sealing efficiency, reduces boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: To guarantee the integrity and reliability of the welds, premium finned tubes must undergo rigorous welding strength assessments, including pull-out force tests that require exceeding 200MPa.
7. Specific design applications: Specially designed for power plant boilers, industrial boilers, and flue gas waste heat recovery systems, double H-shaped finned tubes offer superior heating surfaces and heat transfer efficiency compared to standard finned tubes due to their distinctive design.
