Product Description

Description of H-fin boiler Finned Tubes

The heat transfer tube of the boiler incorporates innovative H-shaped fin tubes. These are crafted by welding two steel strips with arcs symmetrically onto the central tube, creating distinctive fins (ribs). The front profile resembles the letter 'H', thus earning the name H-finned tube. The rectangular fins of the H-finned tube are almost square, boasting a length approximately twice the diameter of the tube, significantly expanding the heating surface area for enhanced thermal performance. The H-finned tube can be exquisitely crafted into a 'double H' finned tube design featuring a dual-tube structure. This configuration offers superior rigidity, making it ideal for extended tube arrangements.

H fin tubes are pivotal in capturing waste heat from power station boilers, industrial boilers, kilns, ship power plants, and more. They dramatically enhance fuel efficiency as heat exchange elements strategically positioned at the tail of the system flue.

Detail

H-type finned tube heat exchanger elements deliver remarkable heat transfer capabilities, exhibit excellent self-cleaning properties, and efficiently reclaim flue gas waste heat, particularly during boiler upgrades. The convective heat transfer coefficient is directly proportional to fin pitch while being inversely proportional to both fin height and width, optimizing heat exchange dynamics. The integrated heat transfer capacity hinges on fin efficiency, convective heat transfer coefficient, and the ratio of fins, ensuring optimal thermal management. Pressure drop tends to rise with increased fin height and width, necessitating careful design balance for effective thermal management.

H-type finned tubes have gained widespread adoption in boilers and waste heat recovery systems, thanks to their enhanced heat exchange efficiency and expansive surface area for heat transfer. H-type finned tubes mainly evolve from rectangular finned tubes, offering similar yet advanced heat exchange benefits. With a unique groove structure on the fin surface, H-type finned tubes excel in anti-wear and anti-fouling attributes, ensuring long-lasting performance.

Our products are customizable to meet the specific needs and conditions of our customers. We specialize in designing and manufacturing safe, reliable, and efficient H-fin tubes.

Economizer H Type Extruded Fin Tubes are available in various materials like copper and stainless steel, addressing diverse application requirements. The low fin design ensures compact and lightweight configurations, ideal for installations where space is a premium.

This finned tube is perfectly suited for integration into air coolers, radiators, and a myriad of other heat exchanger applications. A meticulously crafted manufacturing process ensures precise dimensions and tight tolerances, facilitating seamless integration into current systems.

Product Details

Unmatched Advantages of H-Finned Tube:

The H-finned tube stands as the premier heat exchange component within the entire exhaust gas boiler system, offering remarkable advantages that set it apart.

(1) Outstanding Wear Resistance

Arranged in a precise alignment, the H-finned tube heat exchanger ingeniously subdivides space into several small sections, effectively equalizing airflow. Compared to the staggered arrangement of smooth tube heat exchangers and spiral finned variants, the H-finned tube boasts a wear life 3 to 4 times longer under identical conditions.

(2) Minimized Fouling

Fouling typically occurs on the dorsal and windward sides of the tube. The staggered arrangement facilitates easy flushing of the tube bundle, minimizing fouling on the backside. When subjected to optimal wind speed, the tube exhibits excellent self-cleaning capabilities. Straight channels formed on both sides of the H-finned tube optimize soot management, achieving superior soot removal with the use of a soot blower.

(3) Decreased Exhaust Gas Resistance

With straight channels crafted by the H fins and airflow direction guided by the spiral angle of other fins, the H-finned designs offer reduced susceptibility to fouling and lower flue resistance than their counterparts. Consequently, the adoption of H-finned tubes effectively diminishes wind resistance, leading to decreased operational and investment costs for fans.

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

Thanks to the innovative zigzag structure of the H fins (patented), the welding fusion rate between fins and steel pipes can reach an impressive 98% or more, ensuring an excellent heat transfer coefficient.

(5) Compact Design for Maximum Heat Efficiency

Boasting a heating area per unit length 7.8 times that of smooth tubes, H-finned tubes feature butt welds executed with argon arc welding, significantly enhancing welding quality over manual methods. With substantial reductions in size and weight, the equipment investment is minimized, and users benefit from greater space for equipment installation on equivalent heat transfer surfaces.

(6) Shock Absorbing and Noise Reducing

The unique structural design of the H-finned tube integrates muffler characteristics, enabling the equipment to function as an effective noise reducer.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward, requiring only a connection to the exhaust gas outlet of HFO engine units to commence standard operation. The exhaust gas boiler incorporates a check door, allowing for cleaning cycles tailored to actual conditions, thus ensuring optimal heat transfer and extended working life.
