Product Description

Description of H-fin Boiler Finned Tubes

The boiler employs cutting-edge H-shaped fin tubes for its heat transfer capabilities. These tubes are engineered by skillfully welding two arcuate steel pieces symmetrically onto the raw tube, creating a profile reminiscent of the letter 'H'. Aptly named the H-finned tube, this design revolutionizes heat transfer efficiency. Exquisite in design, the rectangular fins of the H-finned tube are nearly square, extending to a length about twice the tube's diameter. This extension provides an amplified heating surface, significantly boosting performance. For enhanced structural integrity, the H-finned tube can be crafted into a 'double H' finned tube with a dual-tube configuration. This offers remarkable rigidity, making it suitable for extended tube arrangements.

The innovative H fin tube excels in reclaiming waste heat from power station boilers, industrial boilers, kilns, ship power plants, and more. It elevates fuel utilization through enhanced heat exchange, strategically positioned at the system flue's tail for optimal performance.

Detail

H-type finned tube elements set a benchmark in heat transfer capability, boasting exceptional self-cleaning properties. They demonstrate unparalleled efficiency in recovering flue gas waste heat, especially during boiler retrofits. The convective heat transfer coefficient correlates directly with fin pitch, while inversely with fin height and width, creating a fine-tuned balance for optimum performance. Integrated heat transfer prowess hinges on fin efficiency, convective heat transfer coefficient, and finned ratio, orchestrating a symphony of thermal excellence. As fin height and width increase, so does the pressure drop, a factor critical to maintaining streamlined operations.

To achieve remarkable heat exchange efficiency and expanded surface heat transfer, H-type finned tubes have become indispensable in boilers and waste heat recovery systems in recent years. H-type finned tubes have evolved significantly from traditional rectangle finned tubes, continually enhancing thermal effectiveness. Thanks to their unique groove structure on the fin surface, H-type finned tubes exhibit exceptional anti-wear and anti-fouling properties, making them a durable choice.

We take pride in our ability to tailor products to meet specific customer requirements. Our H-fin tubes are meticulously designed and manufactured to ensure safety, reliability, and efficiency.

The Economizer H Type Extruded Fin Tube is available in diverse materials, such as copper and stainless steel, offering versatility to meet varying demands. The low fin design ensures compactness and reduced weight, making this tube an ideal solution for installations where space is at a premium.

This finned tube is perfectly suited for air coolers, radiators, and an array of heat exchanger applications, showcasing its versatility. A sophisticated manufacturing process ensures precise dimensions and tight tolerances, facilitating seamless integration into existing systems and maximizing efficiency.

Product Details

Advantages of H-finned tube:

The H-finned tube is the central heat exchange marvel within the entire exhaust gas boiler system. This component boasts numerous superior features.

(1) Unmatched Wear Resistance

Ingeniously designed, the H-finned tube heat exchanger is meticulously aligned, allowing the H fins to divide the space into smaller zones, thereby harmonizing air flow. Compared to smooth tube exchangers or those with spiral fins, this configuration offers a wear life that is 3 to 4 times more enduring.

(2) Significantly Reduced Fouling

Fouling typically forms on the dorsal and windward sides of the tube, posing challenges. However, the strategically staggered arrangement of the tubes facilitates easy flushing of the tube bundle, significantly minimizing fouling on the reverse side. At optimal wind speeds, it demonstrates an impressive self-cleaning capability. The straight channels formed on either side of the H-finned tube effectively manage soot accumulation, optimizing the soot cleaning process when utilizing a soot blower.

(3) Minimized Exhaust Gas Resistance

Thanks to the straight channels crafted by H fins and the airflow directionality provided by spiral angles, the H fins avoid excessive fouling and offer less flue resistance than traditional options. Thus, implementing H-finned tubes significantly cuts down wind resistance, thereby reducing fan operational and investment expenditures.

(4) Exceptionally High Welding Fusion Rate

With a patented zigzag design, the H fins achieve an impressive weld fusion rate exceeding 98%, ensuring optimal heat transfer efficiency between fins and steel pipes.

(5) Compact Structure with Enhanced Heat Efficiency

Featuring a vast heating area per unit length—7.8 times that of smooth tubes—the H finned tube uses state-of-the-art argon arc welding for superior weld quality compared to manual methods. This leads to remarkably reduced equipment size and weight, minimizing investment costs for equivalent heat transfer surfaces, and offers larger installation spaces for users.

(6) Superior Shock-Proof and Noise Reduction Capabilities

Thanks to its innovative design and inherent structural attributes, the H finned tube acts as a natural muffler, enhancing the device’s shock-absorption and noise-reduction performance.

(7) Simplified Installation, Operation, and Maintenance

Installation is straightforward; simply connect the system to the exhaust gas outlet of HFO engine units, and it’s ready for smooth operation. The exhaust gas boiler, equipped with an inspection door, allows for tailored cleaning cycles based on actual usage, guaranteeing optimal heat transfer and extending the operational lifespan.
