The fins on the boiler superheater tubes are ingeniously engineered structural components that significantly boost heat transfer efficiency. Primarily crafted to expand the heating area, these fins elevate the heat transfer rate dramatically. Constructed from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they exhibit exceptional resistance to high temperatures and corrosion, ensuring a prolonged, stable operational life. In the manufacturing of these fins, we meticulously balance cost efficiency with cutting-edge processing technology.
Fins offer an effective solution to the challenge of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area, compromising efficiency. By employing fins, not only is the heat transfer area restored, but operational costs are also reduced significantly. This results in lower fuel consumption and enhanced boiler efficiency, representing a substantial return on investment.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins expand the surface area on the exterior of the tube, allowing the smoke flowing between them to transfer heat more effectively to the internal medium, typically steam. This innovative design exponentially boosts heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: With an expanded heating area comes a higher heat transfer coefficient, ensuring a rapid and highly effective heat transfer process. This enhancement is critical for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins can be spirally shaped, enveloping the steel pipe and secured by high-frequency welding, guaranteeing durability and resistance to detachment. Alternatively, they can be designed as separate circular sheets, addressing issues like dust accumulation and reducing dead corners in specific applications.
4. Membrane wall application: When finned tubes are integrated into water-cooled wall structures, they form what is known as a 'membrane wall.' This not only expands the heating surface but also enhances sealing performance, minimizes boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, ensuring the welding component's stability and dependability.
7. Specific design applications: Innovations like double H-shaped finned tubes offer superior heating surfaces and heat transfer efficiency compared to standard finned tubes. These advancements are pivotal in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, delivering unmatched performance.
