The fins, an integral structural component on the boiler superheater tubes, are meticulously engineered to enhance heat transfer efficiency. Their primary role is to magnify the heating area, thereby significantly boosting the rate of heat transfer. Crafted from premium metals like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional resistance to high temperatures and corrosion, ensuring long-term stability and operation. In manufacturing, we meticulously balance cost-effectiveness with cutting-edge processing technology to deliver superior quality.
By incorporating fins, the challenge of scaling on the inner walls of boiler superheater tubes is effectively addressed. Scaling traditionally diminishes the heat transfer area of the tube walls, thereby compromising efficiency. With fins, not only is this issue mitigated, but operating costs are also significantly reduced. The fins lower fuel consumption while boosting boiler efficiency, leading to cost savings and enhanced operational performance.
Functional characteristics of boiler tube fins:
1. Increase heating area: By expanding the surface area on the tube's exterior, the fins allow smoke to proficiently transfer heat to the internal medium, typically steam. This design dramatically augments the heat transfer capacity per unit volume, driving performance to new heights.
2. Improve heat transfer efficiency: The expanded heating area is directly proportional to a heightened heat transfer coefficient. This translates to a faster, more effective heat transfer process, critical for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins can be spiral-shaped, wrapping continuously around the steel pipe and secured with high-frequency welding for unmatched stability. Alternatively, they may be individually circular, which can potentially alleviate dust accumulation and reduce dead zones in specific applications.
4. Membrane wall application: When utilized in water-cooled wall structures as finned tubes, known as 'membrane walls,' they not only expand the heating surface but also enhance sealing performance, minimize boiler air leakage, and elevate overall thermal efficiency.
6. Welding strength and stability: Top-tier finned tubes undergo rigorous welding strength evaluations, including pull-out force tests exceeding 200MPa. This ensures the welding sections' stability and reliability, guaranteeing superior performance.
7. Specific design applications: Double H-shaped finned tubes, with their innovative design, deliver superior heating surfaces and heat transfer efficiencies compared to conventional finned tubes. These are ideal for power plant boilers, industrial boilers, and flue gas waste heat recovery systems, offering unmatched performance and efficiency.
