Product Description

Description of H-fin Boiler Finned Tubes

The innovative heat transfer tube of the boiler is crafted using H-shaped fin tubes, characterized by the precise welding of two pieces of steel with central arcs onto the raw tube. This symmetric arrangement forms distinguished fins (ribs) reminiscent of the letter 'H', hence, earning them the name H-finned tubes. The fins on the H-finned tubes are meticulously designed to be rectangular, closely resembling a square. With a length approximately double the diameter of the tube, these fins offer an extended heating surface that maximizes thermal efficiency. Elevate your system's performance with the 'double H' finned tube configuration, featuring a robust double-tube design. This structural innovation provides unparalleled rigidity and is ideally suited for applications requiring extended tube rows.

H fin tubes play a pivotal role in the recovery of gas waste heat across various sectors, including power station boilers, industrial boilers, kilns, and marine power plants. They significantly enhance fuel utilization rates and are strategically positioned as heat exchange elements at the flue's tail end.

Detail

Our H-type finned tube heat exchanger components stand out for their outstanding heat transfer capabilities, remarkable self-cleaning properties, and effective flue gas waste heat recovery, making them ideal for boiler renovation projects. The convective heat transfer coefficient is intricately linked to the fin pitch; a direct proportionality exists, while it is inversely related to both fin height and width for optimal thermal dynamics. The integrated heat transfer capacity is a nuanced interplay of fin efficiency, the convective heat transfer coefficient, and the finned ratio, driving superior performance. As the fin height and width increase, so does the pressure drop, necessitating careful consideration in system design for optimal efficiency.

H-type finned tubes have surged in popularity for their ability to enhance heat exchange efficiency and extend heat transfer surfaces, becoming a cornerstone in modern boilers and waste heat recovery systems. Derived from the highly effective rectangle finned tubes, H-type finned tubes have emerged as a superior choice in heat exchange technology. Boasting a unique groove structure on their fin surface, H-type finned tubes deliver exceptional anti-wear and anti-fouling performance, ensuring long-term reliability.

We offer customization of our products, tailoring them to specific customer needs and situational requirements. Our commitment is to design and manufacture H-fin tubes that are safe, reliable, and efficient.

The Economizer H Type Extruded Fin Tube is available in a variety of materials, including copper and stainless steel, to meet diverse application requirements. The low fin design ensures a compact and lightweight structure, making it the perfect choice for installations where space is at a premium.

This versatile finned tube excels in applications such as air coolers, radiators, and other heat exchanger systems, offering exceptional adaptability. Precision engineering is at the heart of our manufacturing process, resulting in dimensions and tolerances that align seamlessly with existing system integrations.

Product Details

Advantages of H-Finned Tube:

The H-finned tube stands as the pivotal heat exchange element within the entire exhaust gas boiler system. These H-finned tubes boast a plethora of advantages that elevate their performance.

(1) Exceptional Wear Resistance

With a meticulously designed in-line arrangement, the H finned tube heat exchanger ingeniously partitions space into smaller segments. This strategic design ensures an even airflow distribution, vastly enhancing wear resistance—proving to be 3 to 4 times more durable than smooth tube heat exchangers arranged in staggered formations or those with spiral fins.

(2) Minimized Fouling

Fouling primarily occurs on the dorsal and windward sides of the tube. The staggered tube arrangement greatly facilitates the flushing process, minimizing fouling, especially on the backside. At optimal wind speeds, it effectively performs a self-cleaning function. Both sides of the H finned tube form straight channels, optimizing soot removal when combined with a soot blower, achieving superior cleaning results.

(3) Reduced Exhaust Gas Resistance

The distinctive straight channels created by the H fins, coupled with the directional guidance provided by the spiral fins, significantly lower the chances of fouling and flue resistance compared to traditional fin designs. Consequently, utilizing the H-finned tube not only diminishes wind resistance but also curtails fan operation costs and investment expenditure.

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

Thanks to the patented zigzag structure of the H fins, the weld fusion rate between fins and steel pipes can soar to an impressive 98% or more, ensuring optimal heat transfer efficiency.

(5) Compact Structure, Enhanced Heat Efficiency

The expansive heating area per unit length of the H finned tube is phenomenally 7.8 times greater than that of a smooth tube. With butt welds crafted through precision argon arc welding, the welding quality is substantially superior to manual methods. This compact design significantly reduces equipment size and weight, cutting down investment costs while offering more installation space, thus enhancing user convenience.

(6) Shock-Proof and Noise Reduction

Ingenious structural design and the inherent characteristics of the H finned tube impart it with superb muffling capabilities, allowing the equipment to effectively function as a noise dampener.

(7) Ease of Installation, Operation, and Maintenance

Installation is simplified—merely connect the equipment to the exhaust gas outlet of HFO engine units to commence normal operation. Equipped with a check door, the exhaust gas boiler allows for cleaning cycles to be tailored to actual conditions, ensuring consistent heat transfer efficiency and prolonging the system's operational life.
