The fins meticulously designed for the boiler superheater tubes are not merely structural components but pivotal elements that significantly elevate heat transfer efficiency. Through their sophisticated design, they predominantly amplify the heating area, consequently boosting the rate of heat transfer. Crafted from robust metals, such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins showcase exceptional resistance to high temperatures and corrosion, ensuring unwavering and reliable long-term performance. During their manufacture, the cost-effectiveness and advanced processing techniques are meticulously considered, epitomizing our commitment to excellence.
The strategic implementation of fins is a remarkably effective solution to the pervasive issue of scaling within the inner walls of boiler superheater tubes. Scaling notoriously diminishes the heat transfer area of the tube walls, leading to a decline in heat transfer efficiency. By integrating fins, not only is this challenge adeptly addressed, but it also results in a substantial reduction in the operational costs of boilers. Moreover, it significantly cuts down on fuel consumption while simultaneously enhancing the overall efficiency of the boiler.
Functional characteristics of boiler tube fins:
1. Increase heating area: By augmenting the external surface area of the tube with fins, the heat exchange process is markedly improved. The smoke traversing the spaces between the fins can effectively transfer its thermal energy to the medium inside the tube, typically steam, thereby exponentially enhancing the heat-transfer capability per unit volume.
2. Improve heat transfer efficiency: The correlation between an expanded heating area and a heightened heat transfer coefficient is profound. This relationship ensures that the heat transfer process is not only more rapid but also exceptionally effective, playing a crucial role in optimizing boiler efficiency and precise steam temperature regulation.
3. Diverse structural forms: Fin designs exhibit remarkable diversity, ranging from spiral configurations that completely envelop the steel pipe, secured through high-frequency welding for enhanced durability, to separate circular sheet forms that effectively mitigate dust accumulation and dead corners in specific applications.
4. Membrane wall application: In the realm of water-cooled wall structures, the deployment of finned tubes transforms it into a 'membrane wall'. This innovation not only amplifies the heating surface but also significantly enhances sealing performance, curtails boiler air leakage, and markedly improves overall thermal efficiency.
6. Welding strength and stability: For finned tubes of the highest quality, rigorous welding strength assessments are imperative. These include pull-out force tests exceeding 200MPa, ensuring the utmost stability and reliability of the welds.
7. Specific design applications: Notably, double H-shaped finned tubes, with their distinctive design, offer superior heating surfaces and enhance heat transfer efficiency beyond what conventional finned tubes can achieve. These are particularly advantageous in power plant boilers, industrial boilers, and systems for recovering flue gas waste heat.
