The innovative fins installed on the boiler superheater tubes serve as an essential structural enhancement to boost heat transfer efficiency. These fins primarily expand the heating area, resulting in improved heat transfer rates. Crafted from premium materials such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, and more, they demonstrate exceptional resistance to high temperatures and corrosion. This ensures consistent, stable operation over the long term. During the fin manufacturing process, both cost-effectiveness and advanced processing techniques are meticulously considered to achieve optimal results.
Employing fins is an effective solution to tackle scaling issues on the inner walls of boiler superheater tubes. Scaling reduces the heat transfer area and efficiency, but the addition of fins counteracts this effect. Moreover, fins contribute to significant operational cost reductions by decreasing fuel consumption and enhancing overall boiler efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Increase Heating Area: Fins augment the outer surface area of the tube, allowing the smoke passing between them to efficiently transfer heat to the medium inside (typically steam). This design significantly boosts the heat transfer capacity per unit volume, optimizing performance.
2. Improve Heat Transfer Efficiency: The enlarged heating area directly correlates with a heightened heat transfer coefficient. This results in a swifter and more effective heat transfer process, which is vital for maintaining boiler efficiency and precise steam temperature regulation.
3. Diverse Structural Forms: Fins may be spirally shaped, continuously encircling the steel pipe and secured with high-frequency welding for robust attachment; alternatively, they can take the form of individual circular sheets. Although subjected to singular force, the latter design may mitigate dust accumulation and dead spots in certain applications.
4. Membrane Wall Application: In water-cooled wall structures, the use of finned tubes is referred to as a 'membrane wall'. This innovation not only extends the heating surface but also enhances sealing performance, reduces boiler air leakage, and elevates overall thermal efficiency.
6. Welding Strength and Stability: High-quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of the welded joints.
7. Specific Design Applications: For instance, double H-shaped finned tubes, with their distinctive configuration, offer superior heating surfaces and heat transfer efficiency over standard finned tubes. These are particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
