The fins utilized on the boiler superheater tubes are pivotal components engineered to significantly boost heat transfer efficiency. They primarily expand the heating area, thus enhancing the rate of heat transfer. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast superior high-temperature and corrosion resistance, ensuring sustained stable operation over extended periods. During fin production, careful consideration is given to the balance of cost-effectiveness and processing technology, ensuring optimal performance and value.
Integrating fins effectively addresses the prevalent issue of scaling on the inner walls of boiler superheater tubes. Scaling diminishes the tube wall's heat transfer surface area, consequently lowering heat transfer efficiency. By incorporating fins, not only is scaling mitigated, but operational costs are also reduced. This is achieved by decreasing fuel consumption and enhancing overall boiler efficiency, marking a significant leap in operational performance.
Functional Characteristics of Boiler Tube Fins:
1. Enhanced Heating Area: The addition of fins increases the external surface area of the tube, allowing the smoke traversing between the fins to transfer heat more effectively to the medium inside the tube, typically steam. This ingenious design substantially elevates the heat transfer capacity per unit volume, optimizing performance.
2. Augmented Heat Transfer Efficiency: A larger heating area directly correlates with an elevated heat transfer coefficient, signifying a more rapid and efficient heat transfer process. This improvement is crucial for maximizing boiler efficiency and maintaining precise steam temperature control.
3. Versatile Structural Forms: The fins can adopt various structural configurations. Whether spiral-shaped, encircling the steel pipe and securely fixed by high-frequency welding, or as independent circular sheets, they each offer unique advantages. While spirals enhance durability, circular sheets can minimize dust buildup and dead zones in certain applications.
4. Membrane Wall Application: When finned tubes are implemented in water-cooled wall structures, they are known as "membrane walls." This application not only amplifies the heating surface but also enhances sealing performance, curtails boiler air leakage, and elevates overall thermal efficiency, thereby revolutionizing the thermal management of boilers.
6. Welding Strength and Stability: High-quality finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of the welding joints. This stringent testing assures supreme durability and performance.
7. Specialized Design Applications: For instance, double H-shaped finned tubes, owing to their distinctive design, deliver superior heating surfaces and heightened heat transfer efficiency compared to traditional finned tubes. This is particularly advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, offering unparalleled performance enhancements.
