Product Description

Exquisite Overview of H-fin Boiler Finned Tubes

The boiler's state-of-the-art heat transfer tube incorporates the pioneering H-shaped fin tubes, ingeniously crafted by symmetrically welding two pieces of steel with delightful arcs in the middle onto the raw tube, creating remarkable fin structures reminiscent of the letter 'H', aptly named H-finned tube. H-finned tube fins are elegantly rectangular, bordering on square, with a length that impressively extends to about twice the tube diameter, providing an extensive and efficient heating surface. The H-finned tube also boasts a 'double H' version, featuring a robust double-tube structure. This design offers excellent rigidity, making it highly suitable for extended tube rows.

The H fin tube shines in reclaiming gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants, vastly enhancing fuel utilization while strategically positioned at the tail of the system flue for optimal heat exchange.

Detail

H-type finned tube heat exchanger elements are renowned for exceptional heat transfer capabilities, outstanding self-cleaning attributes, and proficiency in flue gas waste heat recovery, especially during boiler renovations. The convective heat transfer coefficient rises with fin pitch, yet diminishes with increasing fin height and width, demanding a precise balance. Integrated heat transfer capacity intricately ties to fin efficiency, coupled with convective heat transfer coefficient and the sophisticated finned ratio. Pressure drop intricately escalates in tandem with fin height and width, necessitating meticulous design considerations.

H-type finned tubes have seen widespread adoption in boilers and waste heat recovery systems recently, owing to their superior heat exchange efficiency and expansive surface heat transfer capabilities. H-type finned tubes predominantly evolve from their rectangle finned tube counterparts, showcasing enhanced performance. The unique groove structure of the H-type finned tubes grants it outstanding anti-wear and anti-fouling properties, ensuring longevity and reliability.

Tailored to customer specifications, our H-fin tubes promise safety, reliability, and efficiency, crafted with precision to meet diverse needs and conditions.

The Economizer H Type Extruded Fin Tube is available in diverse materials, such as copper and stainless steel, to suit varied application requirements. The low fin design not only ensures compactness and lightweight but also makes it perfect for installations with limited space.

This versatile finned tube is perfectly suited for air coolers, radiators, and a myriad of other heat exchanger applications. Its expertly executed manufacturing process guarantees precise dimensions and strict tolerances, facilitating seamless integration into pre-existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the primary component for heat exchange in our comprehensive exhaust gas boiler systems, offering exceptional performance and benefits.

(1) Outstanding Wear Resistance

These heat exchangers are ingeniously arranged in a linear fashion, with H fins dividing the space into distinct zones that help balance airflow. This design surpasses traditional smooth tube and staggered spiral finned heat exchangers, enhancing wear resistance by an impressive 3 to 4 times under similar conditions.

(2) Minimized Fouling

Fouling tends to accumulate mainly on the dorsal and windward sides of the tubes. The staggered tube configuration facilitates easy cleaning, significantly reducing fouling on the backside. With optimal wind speed, this system boasts an excellent self-cleaning capacity. The straight channels formed on each side of the H-finned tubes enable an optimal soot removal effect, especially when using a soot blower.

(3) Reduced Exhaust Gas Resistance

Thanks to the straight channels created by the H fins and the directional guidance of spiral angles, these H fins are less prone to fouling, offering lower flue resistance compared to spiral fins. Thus, adopting H-finned tubes significantly reduces wind resistance, decreasing both fan operation expenses and investment costs.

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

The patented zigzag structure of the H fins ensures a weld fusion rate exceeding 98%, which guarantees an excellent heat transfer coefficient for the H-finned tubes.

(5) Compact Design with High Heat Efficiency

Delivering a heating area per unit length that is 7.8 times greater than smooth tubes, these H-finned tubes feature argon arc welded butt joints, significantly enhancing welding quality compared to manual methods. As a result, the equipment's size and weight are greatly minimized, cutting down on investment costs and providing users with generous installation space.

(6) Vibration and Noise Reduction

The innovative structural design of the H-finned tubes incorporates noise-reducing features, enabling the equipment to serve effectively as a muffler.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward, requiring only a connection to the exhaust gas outlet of the HFO engine units, after which the equipment can commence regular operation. Featuring a check door, the exhaust gas boiler allows for cleaning cycles to be tailored to actual conditions, thereby ensuring optimal heat transfer and prolonging operational lifespan.
