The fins ingeniously integrated onto the boiler superheater tubes serve as a vital component to significantly boost heat transfer efficiency. These innovative fins primarily function to expand the heating area, thereby enhancing the overall heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit outstanding high-temperature and corrosion resistance, ensuring they operate stably and efficiently over the long term. In the fin manufacturing process, careful consideration is given to both cost-effectiveness and processing technology to achieve optimal results.
By incorporating fins, the challenge of scaling on the inner walls of boiler superheater tubes is effectively addressed, as scaling leads to reduced heat transfer areas and decreased efficiency. The strategic use of fins not only counters these issues but also significantly lowers the operational costs of boilers by reducing fuel consumption and enhancing boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: With the addition of fins to the tube's exterior, the surface area expands dramatically, allowing smoke to flow more effectively between the fins and transfer heat to the internal medium, typically steam. This ingenious design substantially boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: A more extensive heating area correlates directly with an elevated heat transfer coefficient, signifying a more rapid and effective heat transfer process. This enhancement is crucial for maximizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse structural forms: Fins showcase versatility, available in spiral shapes that envelop the steel pipe continuously, secured by high-frequency welding for durability and stability. Alternatively, they can be configured as separate circular sheets, aiding in minimizing dust accumulation and dead spots in certain applications.
4. Membrane wall application: When finned tubes are incorporated into water-cooled wall structures, referred to as 'membrane wall,' they augment the heating surface while delivering superior sealing performance. This feature reduces air leakage from the boiler and elevates overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes are subject to rigorous testing to ensure welding strength and stability. These include pull-out force tests that must exceed 200MPa, guaranteeing the reliability and durability of the welded joints.
7. Specific design applications: Unique configurations such as double H-shaped finned tubes offer exceptional heating surfaces and heat transfer efficiency, outperforming standard finned tubes in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
