Product Description

Exquisite Insight into H-Fin Boiler Finned Tubes

The innovative heat transfer tube of the boiler features the remarkable H-shaped fin tubes. These are crafted by symmetrically welding two elegantly curved steel pieces onto the raw tube, forming distinctive fins (or ribs). The front view resembles the letter "H," thus earning the name H-finned tube. The H-finned tube boasts rectangular, nearly square fins, extending approximately twice the diameter of the tube. These fins offer an extended heating surface, optimizing heat exchange. Ingeniously, the H-finned tube can be transformed into a "double H" finned tube, featuring a robust double-tube structure. This design ensures excellent rigidity, making it ideal for longer tube rows.

The H fin tube is adept at recovering gas waste heat from power station boilers, industrial boilers, kilns, marine power plants, and more. It significantly enhances fuel utilization rates, acting as a vital heat exchange element positioned at the flue's tail-end within the system.

Detailed Overview

H-type finned tube heat exchanger elements exhibit outstanding heat transfer capabilities. They possess superior self-cleaning properties and are instrumental in flue gas waste heat recovery during boiler renovations. The convective heat transfer coefficient is directly proportional to fin pitch, yet inversely related to fin height and width, influencing overall performance. The integrated heat transfer capacity intricately depends on fin efficiency, the convective heat transfer coefficient, and the finned ratio, reflecting its robust design. With increased fin height and width, there is a resultant rise in pressure drop, presenting a balance of design considerations.

To elevate heat exchange efficiency and enhance surface heat transfer, H-type finned tubes have seen widespread adoption in boilers and waste heat recovery applications in recent years. H-type finned tubes predominantly derive from rectangle finned tube designs, showcasing an evolution in heat exchange technology. Thanks to their distinctive groove structure on the fin surface, H-type finned tubes excel in anti-wear and anti-fouling performance, ensuring longevity and reliability.

We offer customization of our products to meet our customers' specifications and situational needs. We commit to designing and manufacturing safe, reliable, and efficient H-fin tubes tailored to your requirements.

The Economizer H Type Extruded Fin Tube comes in diverse materials, such as copper and stainless steel, catering to various demands and applications. Its low fin design ensures a compact and lightweight structure, ideal for installations where space is at a premium.

This versatile finned tube is perfect for use in air coolers, radiators, and a broad spectrum of heat exchanger applications. A meticulous manufacturing process ensures precise dimensions and tight tolerances, allowing seamless integration with existing systems for optimal performance.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the central component of superior heat exchange in exhaust gas boilers, offering a plethora of advantages that set it apart.

(1) Exceptional Wear Resistance

Unlike traditional staggered arrangements and spiral finned counterparts, our H finned tube heat exchanger boasts a meticulously aligned design. This strategic configuration divides the space into smaller sections, ensuring optimal air flow distribution. Consequently, the wear life of these tubes surpasses others by an impressive 3 to 4 times under equivalent conditions.

(2) Minimized Fouling

Typically, fouling occurs on the dorsal and windward sides of conventional tubes. Thanks to its staggered design, the tube bundle is easily flushed, significantly reducing fouling on the backside. At optimal wind speeds, it exhibits an exceptional self-cleaning capability. The unique straight channel formed on either side of the H finned tube ensures efficient removal of soot, especially when a soot blower is utilized, achieving unparalleled cleanliness.

(3) Lower Exhaust Gas Resistance

The straight channels molded by H fins, along with the spiral angle of spiral fins, direct airflow effectively, reducing the propensity for fouling and decreasing flue resistance compared to other designs. Deploying H-finned tubes significantly diminishes wind resistance, leading to lower fan operation costs and reduced investment expenditure.

(4) High Fusion Rate of Fins and Steel Pipe

Our patented zigzag configuration of H fins ensures an extraordinary weld fusion rate of 98% or higher with steel pipes, guaranteeing outstanding heat transfer efficiency for H-finned tubes.

(5) Compact Structure with Superior Heat Efficiency

The expansive heating area per unit length of the H finned tube exceeds that of smooth tubes by an astounding 7.8 times. All butt welds are executed using argon arc welding, significantly enhancing welding quality over manual methods. With a considerable reduction in both size and weight, equipment investment costs drop significantly, while providing ample space for user installations, all without compromising on the heat transfer surface.

(6) Vibration Dampening and Noise Reduction

Thanks to its advanced structural design and inherent muffler characteristics, the H finned tube not only performs efficiently but also reduces noise levels, functioning as an effective silencer.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward; simply connect the system to the exhaust gas outlet of HFO engine units to commence standard operation seamlessly. The exhaust gas boiler is outfitted with an inspection door, allowing for cleaning cycle adjustments based on real-time conditions, ensuring optimal heat transfer and extending service life.
