The innovative fins incorporated in the boiler's superheater tubes serve as a pivotal structural element designed to dramatically enhance heat transfer efficiency. Specifically, these fins are engineered to substantially augment the heating area, thereby significantly boosting the heat transfer rate. Crafted from high-grade metals like 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast superior high-temperature endurance and exceptional corrosion resistance, ensuring reliable and stable operation over extended periods. The production of these fins meticulously balances cost-effectiveness with advanced processing technology, guaranteeing optimal performance.
The implementation of fins provides an effective solution for the prevalent issue of scaling inside the boiler superheater tubes. Scaling dramatically diminishes the tube wall's heat transfer area, consequently impairing heat transfer efficiency. By integrating fins, this problem is effectively mitigated, resulting in reduced operational costs. The boilers become more economical to run due to decreased fuel consumption and enhanced boiler efficiency, offering an excellent return on investment.
Functional Characteristics of Boiler Tube Fins:
1. Expansion of Heating Area: The carefully designed fins significantly increase the external surface area of the tubes, ensuring the smoke traveling between these fins transfers heat more efficiently to the medium inside, typically steam. This cutting-edge design substantially amplifies the heat transfer capacity per unit volume, marking a breakthrough in boiler efficiency.
2. Enhanced Heat Transfer Efficiency: A larger heating area correlates with an elevated heat transfer coefficient, ensuring the heat transfer process is remarkably swift and effective. This enhancement is crucial for maintaining optimal boiler efficiency and precise steam temperature control, setting new industry standards.
3. Versatility in Structural Forms: The fins are available in diverse structural configurations, ranging from spiral shapes that continuously envelop the steel pipe and are secured by high-frequency welding, ensuring robustness and durability. Alternatively, they may be designed as separate circular sheets, beneficial in reducing dust accumulation and mitigating dead-corner issues in specific applications.
4. Application in Membrane Walls: When employed within water-cooled wall structures, finned tubes create what is known as a 'membrane wall.' This not only expands the heating surface but also enhances sealing performance, reducing air leakage and significantly boosting overall boiler thermal efficiency.
6. Welding Strength and Stability: Top-tier finned tubes must undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, ensuring the welding joints' stability and reliability. This guarantees the structural integrity and performance longevity of the fins under high operational pressures.
7. Specific Design Applications: Notably, double H-shaped finned tubes, owing to their distinctive design, deliver superior heating surfaces and elevated heat transfer efficiency compared to conventional finned tubes. These are especially beneficial in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, elevating their performance to unprecedented levels.
