The innovative fins on the boiler superheater tubes serve as a sophisticated structural element that significantly boosts heat transfer efficiency. These fins primarily work by expanding the heating area, thereby elevating the heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins demonstrate exceptional resistance to high temperatures and corrosion, ensuring enduring stable operation. The production of these fins carefully balances cost-effectiveness and advanced processing technology.
The integration of fins effectively addresses the scaling challenge on the inner walls of boiler superheater tubes. Scaling can diminish the heat transfer area, adversely impacting heat transfer efficiency. By employing fins, boilers can operate more economically, as they greatly reduce fuel consumption and enhance overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: By expanding the exterior surface area of the tube, the fins facilitate more effective heat transfer from the smoke passing between them to the medium inside—typically steam. This strategic design dramatically amplifies the heat transfer capacity within a given volume.
2. Improve heat transfer efficiency: The expanded heating area is intrinsically linked to an elevated heat transfer coefficient. This correlation ensures that the heat transfer process is swifter and more efficient, which is vital for optimizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse structural forms: The fins are available in various shapes, such as spiral configurations that continuously encircle the steel pipe, secured with high-frequency welding to ensure robustness. Alternatively, they can be separate circular sheets, offering the advantage of minimizing dust accumulation and reducing dead corners in certain applications.
4. Membrane wall application: When finned tubes are incorporated into water-cooled wall structures, they form what is known as a "membrane wall." This application not only enlarges the heating surface but also enhances sealing performance, minimizes boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: Superior quality finned tubes are subjected to rigorous welding strength assessments, including pull-out force evaluations exceeding 200MPa, ensuring the welding part’s stability and reliability under demanding conditions.
7. Specific design applications: Notably, double H-shaped finned tubes, with their distinctive design, deliver greater heating surfaces and superior heat transfer efficiency. These are particularly advantageous in power plant boilers, industrial boilers, and systems for flue gas waste heat recovery.
