The fins applied to boiler superheater tubes play a pivotal role as structural components that significantly elevate heat transfer efficiency. Designed to expand the heating area, these fins are paramount in optimizing the heat transfer rate. Crafted from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they boast exceptional high-temperature resilience and robust corrosion resistance, guaranteeing long-term stable operation. In the manufacturing process, we meticulously balance cost-effectiveness and advanced processing technology to deliver superior quality fins.
By employing fins, the challenge of scaling within the inner walls of boiler superheater tubes is effectively addressed. Scaling tends to diminish the heat transfer area, subsequently reducing efficiency. The integration of fins not only tackles this issue but also lowers the operational costs of boilers by minimizing fuel consumption and enhancing overall boiler efficiency.
Functional Characteristics of Boiler Tube Fins:
1. Increase Heating Area: Fins extend the surface area outside the tube, optimizing the transfer of heat from the smoke flowing between them to the substance within the tube, typically steam. This ingenious design substantially boosts the heat transfer capability per unit volume.
2. Improve Heat Transfer Efficiency: Enlarged heating areas are intrinsically linked to elevated heat transfer coefficients, leading to a faster and more efficient heat transfer process. This aspect is crucial for maintaining boiler efficiency and achieving precise steam temperature control.
3. Diverse Structural Forms: Fins can be crafted in a spiral shape, continuously encircling the steel pipe, secured by high-frequency welding for enhanced durability and resistance to detachment. Alternatively, they can be designed as separate circular sheets, which, while subjected to isolated forces, help mitigate dust accumulation and address dead corners in specific applications.
4. Membrane Wall Application: When incorporated into water-cooled wall structures, these finned tubes are referred to as a 'membrane wall.' This configuration not only augments the heating surface but also enhances sealing performance, curtails boiler air leakage, and bolsters overall thermal efficiency.
6. Welding Strength and Stability: Premium finned tubes are subjected to rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, ensuring unmatched stability and reliability at the welding joints.
7. Specific Design Applications: Take, for instance, double H-shaped finned tubes. Their distinctive design allows for greater heating surfaces and superior heat transfer efficiency compared to conventional finned tubes, particularly in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
