Product Description

Introduction to H-fin Boiler Finned Tubes: A Masterstroke in Heat Transfer Solutions

The revolutionary heat transfer solution for boilers, the H-shaped fin tubes, is ingeniously crafted by welding two pieces of steel with arcs in the middle onto the raw tube. This creates symmetrical fins that resemble the letter 'H', hence the name H-finned tube—a marvel of modern engineering. The H-finned tube boasts rectangular, almost square fins, extending about twice the tube's diameter. This design significantly expands the heating surface, revolutionizing heat transfer efficiency. For superior structural rigidity, the H-finned tube is also available as a 'double H' finned tube. This double-tube innovation is perfect for extended tube arrays, ensuring performance excellence.

The H fin tube reclaims gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants, substantially enhancing fuel efficiency. These heat exchange elements are strategically positioned at the system flue tail.

Detailed Overview of H-type Finned Tube Heat Exchanger Elements

H-type finned tube heat exchanger elements excel in heat transfer, offering remarkable self-cleaning capabilities and optimizing flue gas waste heat recovery during boiler upgrades. The convective heat transfer coefficient is finely tuned by fin pitch and inversely influenced by fin height and width. This balance is key to maximizing efficiency. The integrated heat transfer capacity is intricately linked to fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring unparalleled performance. An increase in fin height and width leads to a rise in pressure drop, a critical consideration in system design.

Recently, H-type finned tubes have become a staple in boilers and waste heat recovery, celebrated for their outstanding heat exchange efficiency and extended surface heat transfer. H-type finned tubes are predominantly derived from rectangle finned tubes, drawing on a legacy of innovation and advancement. With a unique groove structure on the fin surface, H-type finned tubes deliver exceptional anti-wear and anti-fouling performance, setting new standards in durability and longevity.

Our H-fin tubes can be customized to meet specific customer requirements, ensuring safety, reliability, and efficiency in every design and manufacture.

The Economizer H Type Extruded Fin Tube is adaptable, available in materials like copper and stainless steel to meet diverse needs and optimize thermal performance. The innovative low fin design promises compactness and lightweight solutions, making it ideal for installations where space is a premium.

This versatile finned tube is perfectly suited for air coolers, radiators, and various heat exchanger applications, providing flexibility and efficiency. Our advanced manufacturing process guarantees precise dimensions and tight tolerances, ensuring that our finned tubes integrate seamlessly into your existing systems.

Unmatched Advantages of H-Finned Tube:

The H-finned tube stands as the cornerstone of heat exchange in exhaust gas boilers, boasting these remarkable advantages.

(1) Exceptional Wear Resistance

Ingeniously designed, the H finned tube heat exchanger arranges its tubes in line, with H fins creating multiple small areas. This design ensures air flow is evenly distributed. In comparison to other designs like smooth tube exchangers with staggered arrangements or spiral finned exchangers, the wear life impressively outlasts them by 3 to 4 times under equivalent conditions.

(2) Minimized Fouling

Fouling predominantly forms on the dorsal and windward sides of the tube. With its staggered tube arrangement, it efficiently cleans the tube bundle, significantly reducing fouling on the back side. At optimal wind speeds, it exhibits excellent self-cleaning capabilities. The straight channels formed on the sides of the H finned tube optimize soot removal, especially when utilizing a soot blower, for superior results.

(3) Decrease in Exhaust Gas Resistance

Straight channels on both sides of the H fins, coupled with the directional steering of airflow by spiral angles, make H fins less prone to fouling and result in reduced flue resistance compared to their counterparts. Thus, employing H-finned tubes significantly lowers wind resistance, cutting fan operation costs and initial investment.

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

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

(5) Compact Structure with Superior Heat Efficiency

Boasting a heating area per unit length 7.8 times greater than smooth tubes, the H finned tube utilizes argon arc welding for butt welds, markedly enhancing welding quality over manual methods. The significant reduction in equipment size and weight leads to lower investment costs for the same heat transfer surface, offering users more installation space.

(6) Shock-Proof with Reduced Noise

The device's design and the structural properties of the H finned tube endow it with muffler characteristics, allowing it to function efficiently as a noise reducer.

(7) Effortless Installation, Operation, and Maintenance

Installation is simplified by merely connecting 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 cleaning cycles to be tailored to real-time needs, ensuring optimal heat transfer and prolonging service life.
