The innovative design of the fins utilized on the boiler superheater tubes plays a pivotal role in amplifying heat transfer efficiency. Primarily employed to expand the heating surface area, these fins significantly enhance the heat transfer rate. Crafted from superior metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature tolerance and corrosion resistance, ensuring consistent and stable performance over extended periods. During the manufacturing process, a meticulous balance of cost-effectiveness and advanced processing technology is maintained to deliver optimal results.
The strategic application of fins addresses the critical issue of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer surface, consequently hampering heat transfer efficiency. By incorporating fins, not only is the heat transfer area preserved, but boiler operational costs are also reduced. This is achieved through minimized fuel consumption and enhanced boiler performance, leading to significant improvements in overall efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: By expanding the external surface area of the tubes, fins facilitate more effective heat transfer from the smoke flowing between them to the steam or other mediums inside the tubes. This innovative design substantially elevates the heat transfer capacity per unit volume, optimizing the entire heating process.
2. Improve heat transfer efficiency: A direct correlation exists between an increased heating area and a higher heat transfer coefficient. This results in a more rapid and efficient heat transfer process, which is vital for maintaining optimal boiler efficiency and precise control over steam temperature.
3. Diverse structural forms: Fins are available in various configurations, such as spiral shapes that envelop the steel pipe continuously, secured with robust high-frequency welding that resists detachment. Alternatively, they can be fashioned as separate circular sheets, which, despite being subjected to singular forces, help reduce dust accumulation and eliminate dead corners in certain applications.
4. Membrane wall application: When integrated into water-cooled wall structures, finned tubes create what's known as a 'membrane wall.' This not only amplifies the heating surface but also enhances sealing performance, curtails boiler air leakage, and elevates the overall thermal efficiency of the system.
6. Welding strength and stability: To ensure superior quality, finned tubes must undergo rigorous welding strength tests, including pull-out force tests exceeding 200MPa, guaranteeing the stability and reliability of the welded joints.
7. Specific design applications: Specially designed double H-shaped finned tubes offer a remarkable increase in heating surfaces and heat transfer efficiency. These advanced tubes outperform standard finned tubes, particularly in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
