Product Description

Captivating Overview of H-Fin Boiler Finned Tubes

The innovative heat transfer tube of the boiler employs the H-shaped fin tubes, ingeniously designed by welding two pieces of steel with arcs at the center onto the base tube, forming distinctive fins (ribs) that resemble the letter 'H.' This unique configuration has earned the name H-finned tube. Adorned with rectangular-shaped fins that are almost square, the H-finned tube extends its heating surface approximately double the tube's diameter for enhanced performance. The adaptable H-finned tube is also available as a 'double H' finned tube variant, featuring a robust double-tube structure. Its remarkable rigidity makes it suitable for extended tube configurations.

The H fin tube excels in recovering gas waste heat from power station boilers, industrial boilers, kilns, ship power plants, and more. It effectively boosts fuel utilization by strategically positioning the heat exchange element at the system flue's tail.

Detailed Insights

H-type finned tube heat exchanger elements are engineered for optimum heat transfer, boasting superior self-cleaning properties and efficiently facilitating flue gas waste heat recovery during boiler renovations. The convective heat transfer coefficient is directly proportional to fin pitch, while inversely related to both fin height and fin width, ensuring optimal performance. The overall heat transfer capacity hinges on fin efficiency, convective heat transfer coefficient, and the finned ratio, delivering excellent thermal performance. As fin height and width increase, so does the pressure drop, necessitating careful consideration in design.

In recent years, H-type finned tubes have become increasingly prevalent in boilers and waste heat recovery, thanks to their exceptional heat exchange efficiency and extended surface heat transfer capabilities. H-type finned tubes mainly evolve from their rectangular finned counterparts, offering enhanced functionality. H-type finned tubes feature a distinctive groove structure on the fin surface, providing outstanding anti-wear and anti-fouling performance.

Our products can be expertly tailored to meet our customers' unique needs and scenarios. We pride ourselves on designing and manufacturing safe, reliable, and efficient H-fin tubes.

Economizer H Type Extruded Fin Tube is available in a variety of materials, including copper and stainless steel, to accommodate diverse requirements. The low fin design ensures the product remains compact and lightweight, perfectly suited for installations with limited space.

This versatile finned tube is ideal for applications in air coolers, radiators, and other heat exchanger systems. Crafted through a meticulous manufacturing process, it ensures precise dimensions and tight tolerances, enabling seamless integration into existing systems.

Product Details

Advantages of the Revolutionary H-Finned Tube:

The H-finned tube stands as the pivotal heat exchange component within the exhaust gas boiler, offering remarkable advantages that set it apart.

(1) Unparalleled Wear Resistance

Unlike conventional smooth tube heat exchangers with staggered arrangements, the H finned tube heat exchanger boasts a linear alignment, ingeniously dividing the space into small sections. This design ensures uniform air flow distribution, thereby amplifying wear life by an impressive 3 to 4 times.

(2) Minimized Fouling

Fouling tends to occur on both the dorsal and windward sides of the tube. The tube's staggered arrangement facilitates effective flushing of the tube bundle, substantially reducing fouling on the backside. At optimal wind speeds, it exhibits a remarkable self-cleaning ability. The H finned tube forms straight channels, effectively managing soot accumulation, especially when paired with a soot blower for optimum performance.

(3) Lowered Exhaust Gas Resistance

The intelligently designed straight channels formed by H fins, along with the directional guidance of spiral fins, significantly reduce flue resistance compared to other designs. As a result, utilizing H-finned tubes leads to decreased wind resistance, lowering both fan operational costs and capital investment.

(4) Superior Fin-to-Pipe Weld Fusion

The patented zigzag structure of H fins ensures a remarkable weld fusion rate that exceeds 98%, securing an exceptional heat transfer coefficient.

(5) Compact Structure with Enhanced Heat Efficiency

Featuring a vast heating area per unit length—7.8 times greater than smooth tubes—the H finned tube employs argon arc welding for butt welds, significantly surpassing the quality of manual welding. With reduced size and weight, the equipment not only minimizes investment costs but also offers users expanded installation space, all while maintaining a robust heat transfer surface.

(6) Vibration and Noise Reduction Efficiencies

Thanks to its advanced structural design and unique H finned tube characteristics, the equipment serves as an efficient muffler.

(7) Simplified Installation, Operation, and Maintenance

Installation is straightforward, requiring only a connection to the HFO engine units' exhaust gas outlet, facilitating immediate operational readiness. The exhaust gas boiler includes a check door, allowing for cleaning cycle determination based on real-time conditions, thereby optimizing heat transfer and prolonging service life.
