Product Description

Exquisite Description of H-Fin Boiler Finned Tubes

The heat transfer tube of the boiler ingeniously adopts H-shaped fin tubes, crafted by expertly welding two pieces of meticulously shaped steel, each with elegant arcs in the middle, symmetrically onto the raw tube. This results in the formation of distinctive fins (ribs), giving the front view a striking resemblance to the letter "H", hence aptly named the H-finned tube. The fins of the H-finned tube boast a sophisticated rectangular design, almost square, with a length approximately double the diameter of the tube, enhancing the extended heating surface remarkably. The innovative H-finned tube can be skillfully transformed into a "double H" finned tube of double-tube configuration, offering a commendably robust structural integrity, ideal for application in longer tube rows.

H fin tubes are pivotal in the efficient recovery of gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. They substantially boost fuel utilization rates and are strategically positioned as heat exchange elements at the system flue's tail.

 

Intricate Detail

 

H-type finned tube heat exchanger elements are renowned for their exceptional heat transfer capability, outstanding self-cleaning properties, and proficiently facilitate flue gas waste heat recovery during boiler renovations. The convective heat transfer coefficient is intricately linked to fin pitch, yet inversely related to both fin height and width, showcasing a precise balance of design. Integrated heat transfer capacity is intricately associated with fin efficiency, convective heat transfer coefficient, and the sophisticated finned ratio. The pressure drop exhibits an increase with heightened fin dimensions, both in height and width, revealing the delicate interplay of design elements.

 

In the quest to amplify heat exchange efficiency and extend the surface heat transfer, H-type finned tubes have garnered widespread utilization in boilers and waste heat recovery systems recently. H-type finned tubes are primarily derived from the esteemed rectangle finned tubes, offering a rich legacy of performance. Thanks to their unique and ingenious groove structure on the fin surface, H-type finned tubes excel in delivering superior anti-wear and anti-fouling performance.

 

Our products are adeptly adaptable, tailored to meet our customers' specific needs and conditions. We pride ourselves on designing and manufacturing H-fin tubes that are synonymous with safety, reliability, and efficiency.

 

The Economizer H Type Extruded Fin Tube is available in a myriad of materials, including premium copper and stainless steel, to meet diverse requirements with excellence. The low fin design ensures a compact and lightweight profile, perfectly suited for installations where space is at a premium.

 

This remarkable finned tube is the ideal choice for air coolers, radiators, and a myriad of other heat exchanger applications. Its skillfully executed manufacturing process guarantees dimensions of unmatched precision and tight tolerances, ensuring effortless integration into existing systems.

Advantages of H-finned tube:

 

The H-finned tube stands as a pivotal heat exchange component within our advanced exhaust gas boiler system, delivering unmatched efficiency. Here's why the H-finned tube excels:

 

(1) Exceptional Wear Resistance

 

Arranged in a streamlined inline configuration, the H-finned tube heat exchanger ingeniously divides airflow into small zones to balance air flow. This design significantly enhances durability, offering wear life 3 to 4 times greater than traditional smooth tube exchangers with staggered or spiral fin arrangements.

 

(2) Minimized Fouling

 

Fouling typically develops on the dorsal and windward sides of the tube. Thanks to the staggered tube design, it simplifies the cleaning process, resulting in less back-end fouling. At optimal wind speeds, it showcases a robust self-cleaning capability. Straight channels form on both sides of the H-finned tube, optimizing soot removal when combined with a soot blower, achieving superior cleaning results.

 

(3) Reduced Exhaust Gas Resistance

 

With straight channels molded by the H fins and the strategic angle of spiral fins directing airflow, the H fins experience less fouling and lower flue resistance compared to other options. The H-finned tube design significantly cuts wind resistance, thereby reducing both operational costs and fan investment needs.

 

(4) High Welding Fusion Rate

 

Thanks to the patented zigzag structure of the H fins, the fusion rate between fins and steel pipes exceeds 98%, ensuring an excellent heat transfer coefficient.

 

(5) Compact, High-Efficiency Design

 

Boasting a heating area 7.8 times larger per unit length than smooth tubes, the H-finned tube uses argon arc welding for superior butt weld quality, outperforming manual welding. With reduced equipment size and weight, users enjoy substantial savings on equipment investment and installation space, maximizing the usable area.

 

(6) Shock and Noise Reduction

 

Innovative structural design gives the H finned tube a natural muffler capability, reducing noise and vibration effectively.

 

(7) Easy Installation, Operation, and Maintenance

 

Installation is straightforward: simply connect the unit to the exhaust gas outlet of HFO engine units for seamless operation. The exhaust gas boiler features an inspection door, allowing for easy access to determine cleaning cycles based on real-time conditions, optimizing heat transfer efficiency and extending operational lifespan.
