The fins used on the boiler superheater tubes are a pivotal structural component that significantly enhances heat transfer efficiency. Primarily utilized to expand the heating area, these fins effectively improve the heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring long-term stable operation. During fin manufacturing, both cost-effectiveness and processing technology are meticulously considered to deliver optimal performance.
The incorporation of fins offers a compelling solution to the pervasive issue of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area of the tube wall, consequently reducing efficiency. By utilizing fins, this problem is mitigated, leading to enhanced heat transfer efficiency. Moreover, fins significantly cut down the operating costs of boilers by reducing fuel consumption, thereby amplifying boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: These fins considerably augment the surface area on the tube's exterior, allowing the smoke passing between fins to transfer heat more effectively to the medium inside the tube, typically steam. This strategic design dramatically boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: A substantial heating area is directly linked to a heightened heat transfer coefficient. This correlation ensures that the heat transfer process is swift and efficient, which is vital for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: The fins are available in spiral shapes, continuously encircling the steel pipe, and are secured by high-frequency welding, ensuring they are firm and resistant to detachment. Alternatively, they can be in separate circular sheet shapes; while these bear a single force, they may alleviate issues of dust accumulation and dead corners in various applications.
4. Membrane wall application: In water-cooled wall structures, the use of finned tubes is known as a 'membrane wall'. This application not only augments the heating surface but also enhances sealing performance, reduces boiler air leakage, and elevates overall thermal efficiency.
6. Welding strength and stability: Superior quality finned tubes must undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, ensuring the stability and reliability of the welded joints.
7. Specific design applications: Double H-shaped finned tubes, due to their innovative design, deliver superior heating surfaces and heat transfer efficiency compared to standard finned tubes. These are particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
