The cutting-edge fins designed for boiler superheater tubes are vital structural elements engineered to amplify heat transfer efficiency. Primarily, these fins are employed to significantly enlarge the heating area, thereby boosting the overall heat transfer rate. Crafted from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring sustained and reliable long-term operation. The design process of these fins meticulously balances cost-effectiveness and advanced processing technologies.
By integrating fins, the challenge of scaling within the inner walls of boiler superheater tubes is adeptly addressed. Scaling typically diminishes the heat transfer area of the tube wall, consequently lowering heat transfer efficiency. With fin usage, not only is this issue mitigated, but the operational costs of boilers are also reduced, thanks to decreased fuel consumption and enhanced boiler performance.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins are ingeniously designed to augment the surface area surrounding the tube. This allows the smoke passing between the fins to transfer heat to the medium inside the tube—often steam—much more effectively. Such a design substantially boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: The amplified heating area is directly associated with a superior heat transfer coefficient. This means the heat transfer process becomes notably quicker and more efficient, playing a pivotal role in ensuring optimal boiler efficiency and precise steam temperature management.
3. Diverse structural forms: These fins are available in versatile structural designs. They can be spiral, encircling the steel pipe continuously, and are securely fixed through high-frequency welding, ensuring durability and resistance to detachment. Alternatively, they may be fashioned as separate circular sheets, which, although subjected to individual force, might minimize dust accumulation and dead corners in certain applications.
4. Membrane wall application: In structures where water-cooled walls are present, the use of finned tubes is referred to as 'membrane wall' application. This not only expands the heating surface but also enhances sealing performance, curtailing boiler air leakage and elevating overall thermal efficiency.
6. Welding strength and stability: To guarantee the utmost stability and reliability, high-quality finned tubes undergo rigorous welding strength evaluations, including pull-out force tests that must exceed 200MPa.
7. Specific design applications: Unique designs like double H-shaped finned tubes offer considerably higher heating surfaces and enhanced heat transfer efficiency compared to standard finned tubes. These are particularly effective in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
