The fins applied to the boiler's superheater tubes are an indispensable structural innovation, skillfully crafted to dramatically enhance heat transfer efficiency. Their primary role is to expand the heating surface, thereby significantly boosting the rate of heat transfer. Constructed from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast excellent resistance to high temperatures and corrosion, ensuring prolonged and reliable performance. In the manufacturing of these fins, cost-effectiveness and advanced processing technology are meticulously balanced.
By employing fins, the challenge of scaling on the inner walls of boiler superheater tubes is effectively addressed. Scaling diminishes the wall's heat transfer area, thus hampering heat transfer efficiency. Fins not only resolve this issue but also contribute to reducing boiler operational costs by cutting down on fuel consumption and elevating overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The inclusion of fins amplifies the external surface area of the tubes, facilitating more efficient heat transfer from the smoke streaming between the fins to the medium inside the tubes, typically steam. This design innovation markedly boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expanded heating area correlates directly with a heightened heat transfer coefficient, meaning the heat exchange process is considerably accelerated and optimized, which is vital for maximizing boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins come in various configurations; they can be spirally wound around the steel pipe, secured by high-frequency welding for robustness and durability. Alternatively, fins can be designed as separate circular sheets, which, despite bearing a single force, might alleviate dust accumulation and mitigate dead corners in specific scenarios.
4. Membrane wall application: When finned tubes are implemented in water-cooled wall structures, they form what is known as a "membrane wall." This not only augments the heating surface area but also significantly enhances sealing capabilities, curtails boiler air leakage, and elevates the overall thermal efficiency.
6. Welding strength and stability: To ensure durability and dependability, high-quality finned tubes are subjected to rigorous welding strength assessments, such as pull-out force tests that must exceed 200MPa, safeguarding the welding's stability and robustness.
7. Specific design applications: Unique designs like double H-shaped finned tubes offer superior heating surfaces and enhanced heat transfer efficiency compared to standard finned tubes, making them ideal for power plant boilers, industrial boilers, and systems for flue gas waste heat recovery.
