Product Description

Description of H-fin Boiler Finned Tubes

The innovative heat transfer solution for boilers features H-shaped fin tubes, ingeniously crafted by symmetrically welding two arc-shaped steel pieces onto the raw tube. This creates fins that resemble the letter "H," hence the name H-finned tube. The H-finned tube's rectangular fins are almost square, with a length approximately double the tube's diameter, providing an expanded heating surface. For enhanced structural integrity, H-finned tubes can be configured into "double H" finned tubes suitable for longer tube rows, offering superior rigidity.

H fin tubes play a pivotal role in recapturing gas waste heat across various applications such as power station boilers, industrial boilers, kilns, and marine power plants, significantly boosting fuel efficiency. Strategically placed at the system flue's end, they optimize heat exchange.

Detail

H-type finned tube heat exchanger elements are designed to deliver exceptional heat transfer capability, showcasing excellent self-cleaning properties. They effectively facilitate flue gas waste heat recovery during boiler upgrades. The convective heat transfer coefficient directly correlates with fin pitch, yet inversely with fin height and width, highlighting the importance of design precision. Overall heat transfer capacity is a complex interplay of fin efficiency, convective heat transfer coefficient, and finned ratio, offering opportunities for optimization. An increase in fin height and width tends to elevate pressure drop, necessitating careful engineering considerations.

To enhance heat exchange efficiency and surface heat transfer, H-type finned tubes have increasingly been implemented in boiler systems and waste heat recovery operations. H-type finned tubes largely evolve from the concept of rectangular finned tubes, building on their design strengths. Thanks to their specialized groove structure on the fin surface, H-type finned tubes exhibit outstanding anti-wear and anti-fouling properties, making them highly durable.

Our offerings are customizable to meet specific customer demands. We are committed to designing and manufacturing safe, reliable, and highly efficient H-fin tubes.

The Economizer H Type Extruded Fin Tube is available in a range of materials, including copper and stainless steel, to fulfill diverse application needs. With a low fin design, this product promises compactness and lightness, making it perfect for installations with limited space.

This versatile finned tube is ideal for use in air coolers, radiators, and a host of other heat exchanger applications. Its meticulous manufacturing process assures accurate dimensions and strict tolerances, ensuring effortless integration into pre-existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the pivotal heat exchange component in the exhaust gas boiler realm, offering a series of unparalleled advantages.

(1) Outstanding Wear Resistance

The strategic in-line arrangement of the H finned tube heat exchanger ingeniously sections the space into numerous small channels. This configuration adeptly equalizes the airflow, offering a stark contrast to the staggered arrangement of smooth tube heat exchangers or spiral finned heat exchangers. Under identical conditions, the H-finned tube boasts a wear life that is impressively 3 to 4 times higher.

(2) Minimized Fouling

Fouling primarily forms on the dorsal and windward sides of tubes. The staggered tube arrangement facilitates effortless flushing of the tube bundle, significantly reducing fouling on the backside. An optimal wind speed endows it with an excellent self-cleaning capability. The straight channels formed on either side of the H-finned tube ensure maximum soot removal efficiency when utilizing a soot blower.

(3) Reduced Exhaust Gas Resistance

The straight channels crafted by the H fins, coupled with the spiral angle of spiral fins guiding airflow direction, result in fins that are less prone to fouling and exhibit lower flue resistance compared to H fins. Consequently, employing H-finned tubes notably reduces wind resistance, along with a significant decrease in fan operation and investment costs.

(4) High Fusion Rate of Fins and Steel Pipe Welding

Thanks to the distinct patented zigzag structure of the H fins, the weld fusion rate between fins and steel pipes can soar above 98%, ensuring a superior heat transfer coefficient for the H-finned tubes.

(5) Compact Design, Enhanced Heat Efficiency

Boasting a heating area per unit length that is 7.8 times larger than that of a smooth tube, all butt welds are executed with argon arc welding, significantly elevating welding quality beyond that of manual welding. This results in a substantial reduction in equipment size and weight. Thus, for the same heat transfer surface, equipment investment is significantly minimized, granting users more space for equipment installation.

(6) Shock-Proof and Noise Reduction

With a design that incorporates structural features of a muffler, the H finned tube's architectural design provides superb shock absorption and noise reduction capabilities.

(7) Ease of Installation, Operation, and Maintenance

During installation, simply connect the equipment to the exhaust gas outlet of HFO engine units for immediate normal operation. The exhaust gas boiler, equipped with a check door, allows cleaning cycles to be determined based on real-world conditions, ensuring optimal heat transfer and extending operational lifespan.
