Product Description

Exquisite Overview of H-Fin Boiler Finned Tubes

The boiler's heat transfer prowess is elevated by the integration of the H-shaped fin tubes, where two steel pieces are artfully welded with arcs, symmetrically positioned on the raw tube to form fins. Resembling the letter 'H', these are aptly named H-finned tubes. The fins on these H-finned tubes boast a rectangular, nearly square shape, extending approximately twice the diameter of the tube, vastly enlarging the heating surface. The H-finned tube can be innovatively crafted into a 'double H' finned tube configuration, characterized by a robust double-tube structure, making it ideal for extended tube rows.

H fin tubes are indispensable for reclaiming gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. They significantly enhance fuel utilization and are strategically placed at the system flue's tail as a heat exchange element.

 

Product Details and Features

 

H-type finned tube heat exchanger components ensure exceptional heat transfer capabilities, possess remarkable self-cleaning features, and excel in recovering flue gas waste heat, especially advantageous during boiler upgrades. The convective heat transfer coefficient is directly related to fin pitch, yet inversely influenced by fin height and width, optimizing performance. The comprehensive heat transfer capacity hinges on fin efficiency, the convective heat transfer coefficient, and the finned ratio, all working harmoniously. As fin height and width increase, so does the pressure drop, necessitating careful configuration.

 

H-type finned tubes have become an industry standard for enhancing heat exchange efficiency and surface heat transfer, particularly in boilers and waste heat recovery applications. The evolution of H-type finned tubes is traced back to rectangle finned tubes, enhancing performance. Thanks to their distinctive grooved surface, H-type finned tubes offer superior anti-wear and anti-fouling capabilities.

 

Our products are designed for versatility, allowing customization to meet specific customer requirements. We pride ourselves on designing and manufacturing secure, reliable, and efficient H-fin tubes.

 

Economizer H Type Extruded Fin Tubes come in diverse materials like copper and stainless steel, accommodating varied specifications. The low fin design ensures these tubes are compact and lightweight, perfectly suited for installations with limited space.

 

This finned tube is ideal for applications in air coolers, radiators, and other heat exchange systems. Meticulous manufacturing processes guarantee precision in dimensions and tight tolerances, facilitating seamless system integration.

Product Details

Advantages of H-finned tube:

 

The H-finned tube stands as the principal heat exchange component in exhaust gas boilers, offering a multitude of advantages. These attributes make it an indispensable element in enhancing boiler efficiency.

 

(1) Excellent wear resistance

 

In the meticulously aligned H finned tube heat exchanger, the H fins ingeniously partition space into smaller sections, effectively equalizing airflow. Compared to the staggered arrangement of smooth tube heat exchangers or spiral finned heat exchangers, the H finned tube boasts a wear life that is 3 to 4 times greater under similar conditions.

 

(2) Fouling reduced

 

Fouling tends to form on both the dorsal and windward sides of the tube. A staggered tube arrangement facilitates easy flushing of the tube bundle, resulting in considerably less fouling on the backside. At optimal wind speeds, the H-finned tube exhibits an impressive self-cleaning function, maintaining operational efficiency. With straight channels forming on either side of the H finned tube, soot is efficiently managed, achieving optimal results when paired with a soot blower.

 

(3) Reduce the resistance of exhaust gas

 

The strategic design of H fins creates streamlined channels that ease airflow, reducing flue resistance compared to spiral fin arrangements. This design efficiently curtails fouling, offering a marked advantage. Thus, incorporating H-finned tubes reduces wind resistance, leading to decreased fan operation and lower investment costs.

 

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

 

The patented zigzag structure of H fins ensures an impeccable weld fusion rate of 98% or more between fins and steel pipes, guaranteeing a superior heat transfer coefficient.

 

(5) Compact structure, high heat efficiency

 

The H finned tube dramatically amplifies the heating area per unit length-up to 7.8 times that of smooth tubes. Employing argon arc welding for butt welds significantly enhances welding quality over manual methods, ensuring a robust construction. This results in a significant reduction in equipment size and weight, lowering investment costs while providing users with ample installation space.

 

(6) Shock-proof and noise reduced

 

The structural design of the device, combined with the innate properties of the H finned tube, endows the equipment with muffler characteristics, effectively reducing noise and providing shock resistance.

 

(7) Convenient for installation, operation and maintenance

 

Installation is simplified, requiring only a connection to the exhaust gas outlet of HFO engine units to commence normal operation. The exhaust gas boiler is equipped with a check door, allowing for flexible cleaning cycles based on actual conditions, thereby ensuring optimal heat transfer and prolonging the equipment's operational life.
