The innovative fins integrated on the boiler superheater tubes are essential structural components that significantly enhance heat transfer efficiency. These fins are primarily designed to expand the heating area, thereby elevating the heat transfer rate. Crafted from high-performance metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they exhibit outstanding high-temperature and corrosion resistance, ensuring long-lasting, stable operation. During the fin manufacturing process, meticulous attention is given to balancing cost-effectiveness and advanced processing technology.
Implementing fins effectively addresses the common challenge of scaling on the inner walls of boiler superheater tubes. Scaling typically diminishes the heat transfer area of tube walls, thus impacting heat transfer efficiency. By incorporating fins, not only is this problem mitigated, but operational costs of boilers are also reduced. This leads to a decrease in fuel consumption and an enhancement in overall boiler efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Expanded Heating Area: The fins significantly augment the surface area on the exterior of the tube. This expansion allows the smoke flowing between the fins to transfer heat more effectively to the medium within the tube—typically steam. This ingenious design dramatically boosts the heat transfer capacity per unit volume.
2. Enhanced Heat Transfer Efficiency: The augmented heating area is directly linked to an elevated heat transfer coefficient. This results in a more rapid and effective heat transfer process, which is vital for maximizing boiler efficiency and maintaining precise steam temperature control.
3. Versatile Structural Forms: Fins can be designed in various forms, such as spiral-shaped, continuously encircling the steel pipe, and affixed via high-frequency welding for robust attachment. Alternatively, separate circular sheet designs, despite being subjected to single forces, may reduce dust accumulation and prevent dead corners in specific applications.
4. Membrane Wall Application: In water-cooled wall structures, the use of finned tubes creates a 'membrane wall.' This not only enlarges the heating surface but also enhances sealing performance, reducing air leakage in boilers and boosting overall thermal efficiency.
6. Welding Strength and Stability: High-quality finned tubes are required to undergo rigorous welding strength evaluations, such as pull-out force tests that must exceed 200MPa. This ensures the stability and dependability of the welded areas.
7. Specific Design Applications: Exemplified by double H-shaped finned tubes, these uniquely designed tubes offer superior heating surfaces and heat transfer efficiency compared to standard finned tubes, making them ideal for use in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
