Product Description

Description of H-Fin Boiler Finned Tubes

The innovative heat transfer tube of the boiler employs the cutting-edge H-shaped fin tubes. This design involves skillfully welding two pieces of steel, with arcs perfectly crafted in the middle, symmetrically onto the raw tube, forming distinct fins (or ribs). The resulting front shape strikingly resembles the letter 'H', hence the name H-finned tube. The H-finned tube showcases rectangular fins that are nearly square in shape, boasting a length approximately twice the diameter of the tube. This design significantly enhances the extended heating surface area. The H-finned tube can also be ingeniously crafted into a 'double H' finned tube for double-tube systems. With a robust and stable structure, it proves ideal for longer tube rows applications, ensuring reliability and efficiency.

The H-fin tube excels in recovering gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. It significantly boosts the fuel utilization rate while functioning as an efficient heat exchange element, typically located at the tail end of the system flue.

Detail

H-type finned tube heat exchanger elements are designed to maintain superior heat transfer capabilities. They feature exceptional self-cleaning properties, making them ideal for recovering waste heat from flue gases in boiler renovations. The convective heat transfer coefficient is intricately linked to fin pitch, yet inversely related to both fin height and fin width, showcasing the precision of our design. The overall heat transfer capability is influenced by multiple factors including fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring optimal performance. With the rise in fin height and fin width, a corresponding increase in pressure drop is observed, highlighting the importance of precise engineering.

To boost heat exchange efficiency and maximize surface heat transfer capabilities, H-type finned tubes have seen widespread use in modern boilers and waste heat recovery systems in recent years. Primarily developed from rectangle finned tubes, H-type finned tubes offer a leap in efficiency and performance. Thanks to their distinctive groove structure on the fin surface, H-type finned tubes possess outstanding anti-wear and anti-fouling properties, enhancing their longevity and reliability.

Our products are highly adaptable, tailored to meet the specific requirements of our customers. We meticulously design and manufacture H-fin tubes that are safe, reliable, and efficient.

The Economizer H Type Extruded Fin Tube is available in a wide range of materials such as copper and stainless steel, catering to diverse application needs and customer specifications. The innovative low fin design ensures the product remains compact and lightweight, making it an ideal solution for installations where space is at a premium.

This versatile finned tube is perfect for air coolers, radiators, and a variety of other heat exchanger applications, offering flexibility and efficiency. Employing a meticulous manufacturing process, this finned tube boasts precise dimensions and tight tolerances, ensuring it integrates seamlessly into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the cornerstone of heat exchange in exhaust gas boilers, offering exceptional benefits as follows.

(1) Outstanding Wear Resistance

Designed with precision, the H finned tube heat exchanger positions its H fins to partition space into several smaller zones, ensuring a uniform airflow distribution. Unlike smooth tube heat exchangers with staggered setups or spiral finned configurations, this arrangement achieves an impressive 3 to 4 times increase in wear lifespan under similar conditions.

(2) Significantly Reduced Fouling

Fouling typically occurs on the dorsal and windward sides of the tube. Thanks to the staggered tube arrangement, the tube bundle can be flushed more effectively, considerably reducing fouling on the backside. At optimal wind speeds, the H-finned tube showcases a remarkable self-cleaning capability. Straight channels created on both sides by the H fins ensure efficient soot management, especially when paired with a soot blower for optimal performance.

(3) Minimized Exhaust Gas Resistance

H fins create straight channels that guide airflow seamlessly, unlike spiral fins that may contribute to fouling and increased flue resistance. The H fins are ingeniously designed to minimize these issues, leading to a more streamlined airflow. Opting for H-finned tubes translates to reduced wind resistance, which in turn lowers both fan operational demands and investment expenses.

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

With a unique patented zigzag structure, H fins achieve an exceptional weld fusion rate of 98% or higher with steel pipes, ensuring superior heat transfer efficiency.

(5) Compact Structure and Superior Heat Efficiency

Boasting a heating area 7.8 times greater than a smooth tube, the H finned tube maximizes heat efficiency. The superior quality of argon arc welding enhances weld integrity far beyond that of manual welding. This efficiency leads to a remarkable reduction in equipment size and weight, significantly lowering equipment investment while freeing up space for installation flexibility.

(6) Vibration and Noise Reduction

Innovatively designed with muffler-like structural features, the H finned tube reduces vibrations and operates quietly, adding to its list of practical benefits.

(7) Ease of Installation, Operation, and Maintenance

Installation is simplified by connecting the equipment to the exhaust gas outlet of HFO engine units, thus facilitating immediate operational readiness. Equipped with a check door, the exhaust gas boiler allows for maintenance cycles to be tailored based on real-time conditions, optimizing heat transfer efficiency and prolonging operational life.
