The meticulously crafted fins used on boiler superheater tubes are pivotal structural components designed to significantly enhance heat transfer efficiency. Primarily, they serve to expand the heating area, thereby augmenting the heat transfer rate. These fins are masterfully constructed from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, among others. They boast exceptional high-temperature resilience and robust corrosion resistance, ensuring long-term stable performance. During the manufacturing process, the balance between cost-effectiveness and advanced processing technology is meticulously considered.
Incorporating fins presents an innovative solution to the challenge of scaling on the inner walls of boiler superheater tubes. Such scaling issues can diminish the heat transfer area, consequently impeding heat transfer efficiency. By utilizing fins, not only is this problem effectively addressed, but it also leads to reduced operational costs of boilers through lower fuel consumption and an enhancement in boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The strategically designed fins expand the outer surface area of the tube, facilitating a more efficient transfer of heat from the smoke flowing between the fins to the medium inside the tube (commonly steam). This innovative design significantly boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expanded heating area directly correlates to a heightened heat transfer coefficient. This ensures a more rapid and effective heat transfer process, which is crucial for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: The fins exhibit versatile structural designs, including spiral shapes that continuously encircle the steel pipe and are firmly secured by high-frequency welding, ensuring their durability and resistance to detachment. Alternatively, they can be shaped as separate circular sheets, which may help mitigate dust accumulation and eliminate dead corners in certain applications.
4. Membrane wall application: In water-cooled wall structures, finned tubes are termed "membrane walls". This configuration 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: High-quality finned tubes are subjected to rigorous welding strength evaluations, such as pull-out force tests exceeding 200MPa, to assure the welding part's stability and reliability.
7. Specific design applications: Unique designs, such as double H-shaped finned tubes, offer superior heating surfaces and heat transfer efficiency, outmatching ordinary finned tubes in applications like power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
