The innovative fins utilized on the superheater tubes of boilers are key structural elements that significantly enhance heat transfer efficiency. They primarily serve to expand the heating area, thereby boosting the heat transfer rate. Expertly crafted from advanced metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional resistance to high temperatures and corrosion, ensuring long-lasting and stable performance. During the manufacturing process, meticulous attention is given to balancing cost-effectiveness and processing technology for optimal results.
By integrating fins, challenges such as scaling on the inner walls of boiler superheater tubes are effectively addressed. Scaling diminishes the heat transfer area of the tube wall, consequently reducing efficiency. With fins, the operational costs of boilers are significantly lowered by decreasing fuel consumption and enhancing overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins are ingeniously designed to expand the surface area around the tube, allowing smoke to flow seamlessly between them and transfer heat more efficiently to the contained medium, typically steam. This design remarkably boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: The enlargement of the heating area correlates directly with a heightened heat transfer coefficient, making the heat transfer process faster and more efficient. This enhancement is vital for maintaining boiler efficiency and precise steam temperature control.
3. Diverse structural forms: These fins can take on spiral shapes, tightly encircling the steel pipe and secured using high-frequency welding for unmatched stability. Alternatively, they may be separate circular sheets, which can help alleviate dust accumulation and dead corners in specific applications.
4. Membrane wall application: When finned tubes are employed within water-cooled wall structures, this is termed a 'membrane wall.' This configuration not only augments the heating surface but also offers superior sealing capabilities, minimizes boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: Premium-quality finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the stability and dependability of the welded joints.
7. Specific design applications: Unique designs, like double H-shaped finned tubes, deliver enhanced heating surfaces and improved heat transfer efficiency compared to traditional finned tubes. These are particularly advantageous in power plant boilers, industrial boilers, and systems recovering waste heat from flue gases.
