Product Description

Description of H-fin Boiler Finned Tubes

The remarkable heat transfer tube for boilers, ingeniously designed with H-shaped fin tubes, features a unique innovation where two arcs of steel are harmoniously welded onto the raw tube. This meticulously forms fins (ribs) that emulate the shape of the letter 'H', hence its name - H-finned tube. H-finned tubes boast rectangular fins that are admirably near-square in shape, extending approximately twice the diameter of the tube. This exceptional design significantly enhances the heating surface. Ingeniously designed for versatility, the H-finned tube can be transformed into a 'Double H' finned tube, ideal for double-tube configurations. Its robust and sturdy structure makes it perfect for longer tube rows.

The H fin tube is a powerhouse in recovering gas waste heat from power station boilers, industrial boilers, kilns, ship power plants, and more. It elevates fuel utilization efficiency and strategically positions the heat exchange element at the system's flue tail.

Detail

H-type finned tube heat exchanger elements are unmatched in heat transfer capacity, self-cleaning prowess, and flue gas waste heat recovery, especially during boiler renovations. With its advanced engineering, the convective heat transfer coefficient rises with fin pitch, yet decreases with both fin height and width, showcasing optimized performance. The integrated heat transfer prowess hinges on fin efficiency, the convective heat transfer coefficient, and the meticulously calculated finned ratio. Pressure drop intricately escalates along with increases in both fin height and width, requiring precise engineering to balance performance.

To dramatically amplify heat exchange efficiency and augment surface heat transfer, H-type finned tubes have become a mainstay in modern boilers and waste heat recovery applications. Derived primarily from the innovative design of rectangle finned tubes, H-type finned tubes represent a leap forward in engineering. Thanks to their distinctive groove structure on the fin surface, H-type finned tubes excel with outstanding anti-wear and anti-fouling capabilities.

We pride ourselves on tailoring our products to meet the specific needs and scenarios of our customers, crafting H-fin tubes that are synonymous with safety, reliability, and efficiency.

Our Economizer H Type Extruded Fin Tube is crafted from a range of materials, including copper and stainless steel, to meet diverse requirements. The sleek low fin design ensures a compact and lightweight form, perfectly suited for installations where space is at a premium.

This versatile finned tube is perfectly suited for air coolers, radiators, and a wide array of heat exchanger applications. Its precision manufacturing process ensures exact dimensions and stringent tolerances, enabling flawless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube distinguishes itself as the primary heat exchange element within the comprehensive exhaust gas boiler system. This innovative component offers a multitude of advantages, as outlined below.

(1) Excellent wear resistance

The state-of-the-art H finned tube heat exchanger is meticulously aligned in a linear fashion, with its H fins ingeniously segmenting the space into multiple smaller zones. This configuration effectively harmonizes the airflow, offering a remarkable advantage over traditional smooth tube heat exchangers with staggered arrangements, as well as spiral finned exchangers. Under identical conditions, the wear life of H finned tubes is impressively 3 to 4 times longer.

(2) Fouling reduced

Fouling tends to form on both the dorsal and windward sides of the tube. The intelligently staggered tube arrangement facilitates the thorough flushing of the tube bundle, significantly minimizing fouling on the back side. With an optimal wind speed, it boasts a commendable self-cleaning capability. Straight channels formed on either side of the H finned tube allow for superior soot removal when a soot blower is applied, optimizing efficiency.

(3) Reduce the resistance of exhaust gas

H fins on both sides create straight airflow channels, while spiral fins redirect the airflow direction. Unlike spiral fins, H fins are less prone to fouling and present lower flue resistance. As a result, integrating H-finned tubes notably decreases wind resistance, leading to reduced fan operational and investment costs.

(4) Fins and steel pipe welding fusion rate is high

Thanks to the H fins' distinct zigzag design (patented innovation), the weld fusion rate between fins and steel pipes can reach an impressive 98% or more, ensuring an exceptional heat transfer coefficient for H-finned tubes.

(5) Compact structure, high heat efficiency

These tubes offer a substantial heating area per unit length—7.8 times greater than that of smooth tubes. All butt welds benefit from precision argon arc welding, significantly enhancing weld quality over manual methods. This leads to a considerable reduction in equipment size and weight, thereby minimizing equipment investment while offering users ample space for equipment installation and maintenance.

(6) Shock-proof and noise reduced

Ingeniously engineered for structural excellence, the H finned tube's design mimics a muffler, thus doubling as an effective noise reduction solution.

(7) Convenient for installation, operation and maintenance

Installation is simplified: simply connect the equipment to the exhaust gas outlet of HFO engine units and the system is ready for normal operation. An exhaust gas boiler is equipped with a check door, enabling determination of cleaning cycles based on real-world conditions to maintain optimal heat transfer and extend operational longevity.
