Product Description

Detailed Overview of H-Fin Boiler Finned Tubes

Our revolutionary boiler heat transfer tube employs state-of-the-art H-shaped fin tubes. By seamlessly welding two steel arcs symmetrically onto the raw tube, we create dynamic fins (or ribs) that mimic the sleek shape of the letter 'H'. This innovative design is aptly named the H-finned tube. Boasting rectangular, nearly square fins, the H-finned tube features lengths approximately twice the diameter of the tube itself. This design elegantly extends the heating surface, optimizing heat transfer. For enhanced rigidity and application versatility, the H-finned tube can be ingeniously crafted into a 'double H' finned tube, utilizing a robust double-tube structure, perfect for longer tube rows.

Our H fin tube excels in recovering gas waste heat, making it indispensable in power station boilers, industrial boilers, kilns, and ship power plants. By optimizing fuel utilization, it effectively enhances system efficiency, strategically placed at the flue's tail for maximal performance.

In-Depth Specifications

Our H-type finned tube heat exchangers deliver exceptional heat transfer capacity, featuring superior self-cleaning properties that ensure optimal performance. They're pivotal in boiler renovations for efficient flue gas waste heat recovery. A refined convective heat transfer coefficient is directly related to the precision of fin pitch, while inversely impacted by fin height and width, ensuring fine-tuned thermal efficiency. The total heat transfer prowess hinges on fin efficiency, the convective heat transfer coefficient, and the meticulously calculated finned ratio. As fin height and width escalate, so does the pressure drop, necessitating expert design considerations.

To heighten heat exchange efficiency, H-type finned tubes have become the go-to choice for boilers and waste heat recovery systems, gaining widespread acclaim in recent years. H-type finned tubes are primarily inspired by the geometrically advanced rectangle finned tubes, offering superior performance. Thanks to their exceptional groove structure on the fin surface, H-type finned tubes boast impressive anti-wear and anti-fouling capabilities.

Tailored to customer specifications, our H-fin tubes promise safety, reliability, and unparalleled efficiency in design and manufacture.

Our Economizer H Type Extruded Fin Tube stands out with options in copper and stainless steel, catering to diverse material requirements. Designed with a low fin structure, these tubes are not only compact but lightweight, making them perfect for installations where space is at a premium.

This versatile finned tube is ideally suited for air coolers, radiators, and various other heat exchanger applications. Our advanced manufacturing process ensures these tubes meet precise dimensions and tight tolerances, guaranteeing flawless integration into existing systems.

Product Details

Advantages of H-finned Tube:

The H-finned tube stands as the core heat exchange marvel within the entire exhaust gas boiler system, showcasing a multitude of compelling advantages.

(1) Unparalleled Wear Resistance

Ingeniously designed in a linear arrangement, the H finned tube heat exchanger ingeniously segments space into compact zones, optimizing airflow distribution. When compared to staggered smooth tube exchangers or spiral finned counterparts, the H finned tube boasts a wear life remarkably extending up to 3-4 times longer under similar conditions.

(2) Significant Reduction in Fouling

Fouling tends to develop predominantly on the dorsal and windward sides of the tube. The clever staggered tube design facilitates the easy flushing of tube bundles, significantly diminishing fouling on the rear sides. At optimal wind speeds, the system benefits from an effective self-cleaning capability. Straight channels formed along the sides of the H finned tube enhance soot removal efficiency, especially when employing a soot blower for optimal results.

(3) Minimized Exhaust Gas Resistance

The H fins' linear channels guide airflow efficiently, contrasting with spiral fins which are more prone to fouling and provide higher resistance. This makes H fins a superior choice for reducing flue resistance. Adopting H-finned tubes markedly lowers wind resistance, thereby reducing both fan operation demands and associated investment costs.

(4) Superior Welding Fusion Rate of Fins and Steel Pipes

The uniquely patented zigzag structure of H fins boasts an exceptional weld fusion rate exceeding 98%, ensuring optimal heat transfer efficiency in H-finned tubes.

(5) Compact Structure with Outstanding Heat Efficiency

The expansive heating area per unit length of the H finned tube is a remarkable 7.8 times greater than that of smooth tubes. Advanced argon arc welding elevates welding quality far beyond traditional manual methods. With significantly reduced equipment size and weight, this design cuts investment costs while maximizing available installation space, delivering a substantial advantage in heat transfer surface efficiency.

(6) Shock-Proof Design with Noise Reduction

Crafted with a unique structural design, the H finned tube inherently acts as a muffler, thus reducing noise and ensuring a quiet operation.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward; simply connect the system to the exhaust gas outlet of HFO engine units for immediate operation. Featuring a check door, the exhaust gas boiler enables easy determination of cleaning cycles based on actual conditions, thereby enhancing heat transfer efficiency and prolonging equipment life.
