Product Description

Description of H-Fin Boiler Finned Tubes

Our expertly crafted heat transfer tubes for boilers maximize efficiency with the innovative H-shaped fin tubes. These tubes are engineered by symmetrically welding two curved steel pieces onto a raw tube, creating distinctive fins that resemble the letter "H," hence the name 'H-finned tube.' Featuring a rectangular and almost square fin design, the H-finned tubes boast fins that are about twice the length of the tube diameter. This unique structure significantly expands the heating surface area, optimizing heat transfer performance. The H-finned tube can be innovatively engineered into a "double H" configuration, perfect for double-tube systems. This design provides exceptional structural rigidity, making it suitable for longer rows of tubes.

Our H fin tubes are pivotal in reclaiming gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. By integrating these tubes, fuel utilization rates are effectively enhanced, with these heat exchange elements strategically placed at the system flue's tail for optimal performance.

Detail

H-type finned tube heat exchanger elements stand out with their impressive heat transfer capacity. They offer excellent self-cleaning properties and are highly effective in flue gas waste heat recovery, especially beneficial during boiler renovations. The convective heat transfer coefficient has a direct relationship with fin pitch, yet it decreases as fin height and width increase, demonstrating the delicate balance in fin design. The holistic heat transfer capacity is a function of fin efficiency, the convective heat transfer coefficient, and the finned ratio, highlighting the intricacies of superior heat exchanger performance. As fin height and width increase, expect a corresponding rise in pressure drop, underscoring the precision required in fin specifications for optimal efficiency.

To enhance heat exchange efficiency and extend surface heat transfer, H-type finned tubes have become increasingly prevalent for boilers and waste heat recovery applications in recent years. H-type finned tubes, with their roots in rectangle finned tubes, have evolved to meet modern heat exchange demands. Thanks to the distinctive groove structure on their fin surface, H-type finned tubes excel in anti-wear and anti-fouling performances, ensuring durability and maintenance ease.

Our adaptable products can be tailored to meet specific customer requirements and conditions. We specialize in designing and manufacturing safe, reliable, and efficient H-fin tubes, tailored for excellence.

The Economizer H Type Extruded Fin Tube is versatile, available in materials like copper and stainless steel to meet diverse application needs, ensuring it suits any requirement. This intelligent low fin design combines compactness and lightweight attributes, making it the perfect choice for installations where space is limited.

Ideal for air coolers, radiators, and a variety of heat exchanger applications, this finned tube is designed for versatility and high performance. Manufactured with precision, this tube's dimensions and tolerances are meticulously controlled, ensuring seamless integration into your existing systems, enhancing operational efficiency.

Product Details

Compelling Advantages of H-finned Tube:

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

(1) Superior Wear Resistance

Uniquely arranged in a straightforward pattern, the H-finned tube divides the space into multiple smaller zones, ensuring balanced airflow. Compared to smooth tube heat exchangers with staggered layouts or spiral finned alternatives, this arrangement dramatically enhances wear life, lasting 3 to 4 times longer.

(2) Minimized Fouling

Fouling typically occurs on the dorsal and windward sides of the tube. With its staggered tube arrangement, this design effectively flushes the tube bundle, significantly reducing fouling on the backside. Moreover, it boasts an excellent self-cleaning function when wind speed is optimized. The H-finned tube crafts straight channels on both sides, efficiently managing soot. When paired with a soot blower, it achieves optimal soot removal efficiency.

(3) Lower Exhaust Gas Resistance

H fins' linear channels and the strategic angle of spiral fins channel airflow direction, minimizing fouling risk and offering lower flue resistance than spiral fin counterparts. Thus, utilizing H-finned tubes reduces wind resistance, slashing fan operation and investment costs.

(4) Exceptional Welding Fusion Rate

Thanks to their patented zigzag design, H fins achieve a remarkable weld fusion rate of over 98% with steel pipes, ensuring optimal heat transfer efficiency.

(5) Compact Structure with High Thermal Efficiency

Boasting a heating area per unit length that's 7.8 times greater than smooth tubes, the H finned tube features all butt welds executed via argon arc welding, significantly surpassing manual welding quality. This innovative structure substantially reduces equipment size and weight, lowering investment while offering expansive installation flexibility.

(6) Vibration-Resistant and Noise-Reducing

Thanks to its sophisticated structural design, the H finned tube not only provides heat transfer but also functions as an effective muffler, reducing operational noise.

(7) Easy Installation, Operation, and Maintenance

Installation is straightforward: simply connect to the exhaust gas outlet of HFO engine units for seamless operation. Equipped with a check door, the exhaust gas boiler allows for cleaning schedules tailored to real-world conditions, optimizing heat transfer and extending service life.
