Product Description

Description of H-fin boiler Finned Tubes

The innovative heat transfer tube of the boiler utilizes the unique H-shaped fin tubes. This design involves symmetrically welding two pieces of steel with central arcs onto the raw tube, crafting the fins (or ribs) into a shape reminiscent of the letter "H". Thus, this engineering marvel earns the name 'H-finned tube.' The H-finned tube features rectangular, nearly square fins, extending roughly twice the diameter of the tube. This design embellishes the heating surface, ensuring enhanced heat transfer efficiency. For applications requiring robust structural integrity, the H-finned tube can be adapted into a 'double H' finned tube design. This double-tube configuration provides excellent rigidity, perfectly suited for extended tube rows.

The H fin tube excels in capturing gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. It significantly boosts fuel efficiency by performing as a heat exchange element at the tail end of system flues.

Detail

H-type finned tube heat exchanger elements offer exceptional heat transfer capabilities. Distinguished by their superior self-cleaning features, they are adept at flue gas waste heat recovery, making them a valuable asset in boiler renovations. The convective heat transfer coefficient has a direct relationship with fin pitch, yet it inversely correlates with fin height and width, showcasing a sophisticated balance of elements. Integrated heat transfer capacity hinges on fin efficiency, the convective heat transfer coefficient, and the finned ratio, creating a harmonious fusion for optimal performance. An increase in fin height and width leads to a corresponding rise in pressure drop, showcasing a trade-off between design and efficiency.

To amplify heat exchange efficiency and surface heat transfer, H-type finned tubes have seen widespread adoption in boilers and waste heat recovery systems, marking a trend in eco-efficient engineering. Primarily derived from rectangular finned tubes, H-type finned tubes build upon a legacy of innovation and performance. Thanks to their unique grooved surface structure, H-type finned tubes exhibit outstanding anti-wear and anti-fouling properties, proving their durability and reliability.

Our products are tailored to meet customer requirements and situational demands. We prioritize designing and manufacturing H-fin tubes that are safe, reliable, and efficient.

The Economizer H Type Extruded Fin Tube is versatile, offered in materials such as copper and stainless steel, to meet diverse needs. The low fin design ensures a compact, lightweight profile, perfect for installations where space is at a premium.

This finned tube stands out as an ideal fit for air coolers, radiators, and other heat exchanger applications, delivering reliable performance. Our meticulous manufacturing process ensures precise dimensions and tight tolerances, facilitating seamless integration into existing systems without compromise.

Product Details

Advantages of H-finned tube:

The H-finned tube is a pivotal heat exchange component in exhaust gas boilers, boasting remarkable advantages that set it apart in the industry.

(1) Exceptional Wear Resistance

Ingeniously arranged in line, the H finned tube heat exchanger divides space into smaller areas, ensuring uniform airflow. In contrast to staggered and spiral finned heat exchangers, it offers wear life 3 to 4 times greater under identical conditions.

(2) Minimized Fouling

Fouling typically forms on the dorsal and windward sides of the tube. The innovative staggered tube design facilitates easy cleaning, reducing fouling on the backside significantly. At optimal wind speeds, it boasts an impressive self-cleaning capability. The straight channels formed on both sides of the H finned tube effectively remove soot, especially when using a soot blower, achieving optimal results.

(3) Lower Exhaust Gas Resistance

H fins create streamlined channels, directing airflow seamlessly. Unlike spiral fins that accumulate fouling and increase flue resistance, H fins provide a superior alternative. Thus, adopting H-finned tubes means decreased wind resistance, leading to lower operational and investment costs for fans.

(4) Superior Welding Fusion Rate

With its unique patented zigzag structure, the weld fusion rate between fins and steel pipes can exceed 98%, ensuring an excellent heat transfer coefficient.

(5) Compact Structure with High Heat Efficiency

Featuring a large heating area per unit length, the H finned tube surpasses smooth tubes by 7.8 times. Argon arc welding enhances weld quality significantly beyond manual welding. Reduced equipment size and weight lead to lower investment costs, offering more installation space and flexibility for users.

(6) Shock-Resistant and Noise-Reducing

Thanks to its design and the unique structure of the H finned tube, the equipment doubles as an effective muffler, reducing noise and vibrations.

(7) Easy Installation, Operation, and Maintenance

Installation is straightforward: simply connect to the exhaust gas outlet of HFO engine units, and the equipment is ready for operation. Equipped with a check door, the exhaust gas boiler allows for a cleaning schedule tailored to actual conditions, ensuring optimal heat transfer and extending the equipment's lifespan.
