Lord Fin Tube--The advantages of the H type fin tube
The Advantages of the H Type Fin Tube:
1. H Type Fin Tube Exceptional Wear Performance:
- Wear in economizers is primarily caused by the impact and cutting action of ash particles. The H-type fin tube, especially in a line arrangement, exhibits excellent wear resistance.
- The wear is most significant around the 30° horizontal portion of the tube. Staggered arrangements experience less wear due to changes in airflow direction.
- Compared to other tube arrangements, the H-fin tube economizer demonstrates 3-4 times higher wear life under similar conditions, with wear rate proportional to flue gas velocity and ash concentration.
2. H Type Fin Tube Fouling Reduction:
- The H-type fins, with their well-spaced configuration, minimize fouling formation. Fouling occurs mainly on the tube surface and the windward side facing away.
- Staggered tube arrangements facilitate easier cleaning and reduce fouling on the tubes back. In contrast, in-line arrangements are more prone to fouling columns.
- The H-type fins design, with fins welded on both sides of the tube, reduces fouling. The airflow direction remains constant, preventing hard fouling.
- The intermediate gap in H-type fins allows for effective blowing to remove fouling, with a range of 4-10㎜.
3. H Type Fin Tube Compact Space and Reduced Smoke Exhaust Temperature:
- The H-fin tube economizers extended heating surface design offers flexibility in utilizing boiler space efficiently.
- The compact design allows for additional heating surface, leading to a significant reduction in exhaust gas temperature.
- The straight channel formed by H-type fins on both sides optimizes the effectiveness of sootblowers, contributing to overall compactness and efficiency.
