Product Description

Description of H-fin boiler Finned Tubes

The boiler's heat transfer marvel, the H-shaped fin tubes, are ingeniously designed by symmetrically welding two finely-arc-cut steel pieces onto the base tube. This results in a unique, 'H'-like fin structure, aptly named the H-finned tube. The rectangular, nearly square fins of the H-finned tube boast a length approximately double the tube's diameter, offering an expanded heating surface for optimal performance. Crafted with innovation, the H-finned tube can evolve into a robust 'double H' finned tube for double-tube configurations, demonstrating a solid structure ideal for longer tube rows.

The H fin tube is a powerhouse for recovering waste heat from power station boilers, industrial boilers, kilns, and marine power plants. It significantly enhances fuel efficiency, strategically positioned at the system flue's tail for maximum heat exchange.

Detail

The H-type finned tube heat exchanger elements are celebrated for their exceptional heat transfer capacity, outstanding self-cleaning prowess, and unparalleled ability to recover flue gas waste heat, perfect for boiler renovations. The convective heat transfer coefficient increases with fin pitch but decreases as fin height and width grow, highlighting the intricate balance of design. The overall heat transfer capacity hinges on fin efficiency, the convective heat transfer coefficient, and the meticulous finned ratio. Pressure drop is a direct consequence of increasing fin height and width, necessitating precise engineering for optimal performance.

In recent years, H-type finned tubes have gained immense popularity in boilers and waste heat recovery systems due to their enhanced heat exchange efficiency and extended surface area. The evolution of H-type finned tubes is rooted in the rich heritage of rectangle finned tube technology, advancing its legacy. Thanks to their unique grooved surface structure, H-type finned tubes excel in anti-wear and anti-fouling capabilities, making them a top choice for demanding applications.

Our products are customizable to meet specific customer needs, designed and manufactured for excellence in safety, reliability, and efficiency in H-fin tubes.

The Economizer H Type Extruded Fin Tube is versatile, available in materials like copper and stainless steel, to meet diverse requirements with precision. Its low fin design ensures a compact, lightweight profile, perfect for installations where space is at a premium.

Ideal for air coolers, radiators, and other heat exchanger applications, this finned tube embodies versatility and efficiency. Manufactured with precision, this finned tube promises exact dimensions and tight tolerances, facilitating flawless integration into current systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the premier heat exchange marvel within exhaust gas boilers. This innovative component boasts an array of unparalleled advantages that elevate its performance to a new echelon of excellence.

(1) Exceptional Wear Resistance

Ingeniously designed, the H finned tube heat exchanger is meticulously arranged in line. The clever separation of space into distinct areas by the H fins ensures an even air flow. Compared to traditional staggered and spiral finned heat exchangers, this superior design triumphs with a wear life that is 3 to 4 times higher under identical conditions.

(2) Minimized Fouling

Fouling primarily occurs on the dorsal and windward sides of the tube. The strategically staggered arrangement allows for efficient flushing of the tube bundle, significantly reducing fouling on the backside. At optimal wind speeds, it exhibits a remarkable self-cleaning capacity. The meticulously designed straight channels on either side of the H finned tube ensure optimal soot removal efficiency, especially when paired with a high-performance soot blower.

(3) Reduced Exhaust Gas Resistance

The innovative straight channels fashioned by the H fins, combined with the angled spirals of the spiral fins that steer airflow, result in reduced fouling and dramatically lower flue resistance compared to traditional designs. This strategic advantage of H-finned tubes translates to diminished wind resistance, significantly lowering both fan operation costs and initial investment.

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

Thanks to the patented zigzag design of the H fins, the weld fusion rate with steel pipes impressively exceeds 98%, ensuring an exceptional heat transfer coefficient that promises top-tier performance.

(5) Compact Structure, Superior Heat Efficiency

Boasting a heating area per unit length that is 7.8 times larger than that of smooth tubes, the H finned tube benefits from advanced argon arc welding techniques, vastly surpassing the quality of manual welding. With significantly reduced equipment size and weight, the investment in equipment is substantially lower, granting users more space for installation while maintaining a large heat transfer surface.

(6) Vibration and Noise Reduction

The masterful design and structural features of the H finned tube endow the equipment with the ability to function as an effective muffler, ensuring a quieter, more serene operation.

(7) Ease of Installation, Operation, and Maintenance

Installation is a breeze—simply connect the equipment to the exhaust gas outlet of HFO engine units to commence seamless operation. The exhaust gas boiler is equipped with a convenient check door, allowing determination of the optimal cleaning cycle based on real-world conditions to ensure robust heat transfer and prolong the service life.
