Product Description

Detailed Overview of H-Fin Boiler Finned Tubes

The boiler's heat transfer tube features H-shaped fin tubes, ingeniously designed by welding two arc-steel pieces symmetrically onto the central tube. This construction forms distinctive H-like fins, earning them the name H-finned tubes. The rectangular fins on H-finned tubes offer a near-square shape, extending approximately twice the diameter of the tube. This design significantly enhances the heating surface area. Moreover, H-finned tubes can be crafted into 'double H' configurations for double tubes, offering robust structural integrity, ideal for longer tube arrays.

H fin tubes are pivotal in recapturing gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants. They efficiently boost fuel utilization and are strategically placed at the flue's tail for optimal heat exchange.

Product Specifications

The H-type finned tube heat exchanger components excel in heat transfer efficiency, feature outstanding self-cleaning abilities, and play a crucial role in enhancing flue gas waste heat recovery during boiler upgrades. The convective heat transfer coefficient rises with fin pitch, yet decreases with greater fin height and width. Overall heat transfer performance depends on fin efficiency, convective heat transfer coefficient, and finned ratio. An increase in fin height and width will result in a heightened pressure drop.

To elevate heat exchange efficiency and expand surface heat transfer, H-type finned tubes have become a predominant choice in boiler systems and waste heat recovery applications. H-type finned tubes predominantly evolve from rectangular finned designs. Thanks to their specialized groove structure on the fin surface, H-type finned tubes deliver superior anti-wear and anti-fouling capabilities.

Our offerings can be tailored to meet specific customer requirements. We are dedicated to designing and manufacturing safe, reliable, and efficient H-fin tubes.

The Economizer H Type Extruded Fin Tube is available in diverse materials such as copper and stainless steel, meeting various specifications. The low fin design ensures a compact, lightweight profile, perfectly suited for installations where space is at a premium.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the primary heat exchange element in the comprehensive exhaust gas boiler system, offering an array of remarkable benefits.

(1) Exquisite Wear Resistance

Arranged meticulously in a linear fashion, the H-finned tube heat exchanger intelligently segments space into compact zones, ensuring even airflow distribution. This design significantly extends wear life by 3 to 4 times compared to smooth tube exchangers with staggered configurations or spiral finned alternatives.

(2) Effective Fouling Reduction

Fouling typically emerges on the dorsal and windward sides of the tube. The strategic staggered arrangement facilitates easy flushing of the tube bundle, considerably minimizing fouling on the backside. At optimal wind speeds, the system boasts a superb self-cleaning capability. The H-finned tube's design precipitates straight channels on either side, optimizing the soot removal effect when paired with a soot blower.

(3) Minimized Exhaust Gas Resistance

The straight channels formed by H fins, coupled with the spiral angle steering airflow, reduce fouling tendencies and lessen flue resistance compared to spiral fins. Employing H-finned tubes effectively minimizes wind resistance, thereby reducing both fan operational demands and investment costs.

(4) Superior Welding Fusion Rate

Featuring an exclusive zigzag structure (patented), the H fins achieve a weld fusion rate exceeding 98% with steel pipes, ensuring excellent heat transfer efficiency.

(5) Compact Structure with High Heat Efficiency

Boasting a heating area per unit length 7.8 times greater than that of smooth tubes, and utilizing superior argon arc welding for butt joints, it surpasses manual welding in quality. Significantly reduced equipment size and weight lead to decreased investment for equivalent heat transfer surfaces, providing users with enhanced installation flexibility.

(6) Vibration and Noise Reduction

The ingenious structural design of the device and H-finned tubes endows it with muffler characteristics, enhancing its capacity to function as a noise suppressor.

(7) Ease of Installation, Operation, and Maintenance

For installation, simply connect the equipment to the exhaust gas outlet of HFO engine units, where it is ready for seamless operation. Equipped with a check door, the exhaust gas boiler allows for determining the cleaning cycle based on real-time conditions, ensuring optimal heat transfer and longevity.
