The intricately engineered fins employed on the boiler superheater tubes serve as vital structural enhancements that significantly boost heat transfer efficiency. These fins are primarily utilized to expand the heating surface area, resulting in an improved rate of heat transfer. Crafted from premium-grade materials including 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional resistance to high temperatures and corrosion. This robust design ensures the long-term, stable operation of the system. During their manufacture, careful consideration is given to cost-effectiveness and the intricacies of processing technology, ensuring a balanced approach to performance and affordability.
The innovative incorporation of fins effectively addresses the challenge of scaling on the inner walls of boiler superheater tubes. Scaling can significantly diminish the heat transfer surface area, thus compromising efficiency. By deploying fins, this issue is mitigated, enhancing heat transfer efficiency, and consequently reducing operational costs. The fins contribute to decreased fuel consumption and substantially improve the overall efficiency of the boiler system.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins significantly augment the external surface area of the tubes. This design allows the flowing smoke between the fins to efficiently transfer heat to the medium inside the tube, typically steam. This remarkable enhancement substantially boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: A more expansive heating area correlates directly with a higher heat transfer coefficient. This advancement leads to a swifter and more efficient heat transfer process, which is crucial for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: The fins can be designed in a spiral shape, continuously enveloping the steel pipe and secured through high-frequency welding, ensuring a robust attachment that resists detachment. Alternatively, they can be configured as separate circular sheets, which, despite being subjected to individual forces, may alleviate issues like dust accumulation and dead space 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 configuration not only enlarges the heating surface but also offers enhanced sealing performance, reduces boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, ensuring the welding joints’ stability and reliability.
7. Specific design applications: Double H-shaped finned tubes, for instance, with their distinctive design, deliver superior heating surfaces and heat transfer efficiency compared to standard finned tubes. This makes them particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
