Product Description

Enticing Overview of H-fin Boiler Finned Tubes

The innovative heat transfer tube of the boiler features H-shaped fin tubes, achieved by symmetrically welding two pieces of steel with arcs onto the raw tube. This creates the distinctive, efficient 'H' shaped fins (ribs), thus aptly named the H-finned tube. H-finned tube fins are designed as rectangular and nearly square in shape, with a length extending approximately twice the tube's diameter, providing an expansive heating surface for exceptional heat transfer. For enhanced performance, the H-finned tube can be configured into a 'double H' finned tube with double-tube construction. This feature offers robust structural rigidity, making it ideal for longer tube rows.

Our H fin tube is expertly crafted to reclaim gas waste heat from power station boilers, industrial kilns, ship power plants, and more. It significantly boosts fuel utilization efficiency and is strategically positioned as a heat exchange element at the system flue's tail.

In-Depth Detail

H-type finned tube heat exchanger elements boast high heat transfer capacity, superior self-cleaning properties, and are excellent for flue gas waste heat recovery, particularly valuable in boiler renovations. The convective heat transfer coefficient is directly related to fin pitch while inversely related to both the height and width of the fins, ensuring optimal performance. Overall heat transfer capacity is influenced by fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring maximum efficiency. Pressure drop corresponds to the increase in fin height and width, a critical factor in optimizing operational performance.

To achieve superior heat exchange efficiency and extended surface heat transfer, H-type finned tubes have become prevalent in modern boilers and waste heat recovery systems. H-type finned tubes have evolved predominantly from rectangle finned tubes, enhancing their capability and versatility. Thanks to their unique groove structure, H-type finned tubes offer outstanding anti-wear and anti-fouling performance, making them indispensable in rigorous applications.

We offer tailor-made solutions, designing and manufacturing safe, reliable, and efficient H-fin tubes to meet specific customer requirements and situational demands.

Economizer H Type Extruded Fin Tube comes in a selection of materials, including copper and stainless steel, catering to diverse application needs. The low fin design ensures the product remains compact and lightweight, perfectly suited for installations where space is limited.

This versatile finned tube is ideal for use in air coolers, radiators, and various other heat exchanger applications, ensuring flexibility across different systems. Our meticulous manufacturing process ensures that each finned tube boasts precise dimensions and tight tolerances, ensuring smooth integration into any existing system.

Product Details

Advantages of H-finned tube:

The H-finned tube emerges as the pivotal heat exchange element within the entire exhaust gas boiler system, boasting an impressive suite of advantages.

(1) Superior Wear Resistance

The H finned tube heat exchanger, with its in-line arrangement, partitions space into smaller, uniform zones. This design equalizes airflow efficiently. Compared to smooth tube heat exchangers with staggered layouts and spiral finned counterparts, the H-finned tube boasts a wear life 3 to 4 times longer under identical conditions.

(2) Minimized Fouling

Fouling typically forms on the dorsal and windward sides of tubes. Thanks to the staggered tube arrangement, tube bundles can be easily flushed, resulting in significantly reduced fouling on the rear side. The design facilitates an excellent self-cleaning mechanism at optimal wind speeds. The straight channels formed on either side of the H-finned tube effectively manage soot, offering optimal cleaning efficiency when paired with a soot blower.

(3) Reduced Exhaust Gas Resistance

The straight channels formed by the H fins, coupled with the spiral fins' angles, direct airflow efficiently, reducing fouling and flue resistance compared to traditional fins. Thus, utilizing H-finned tubes can significantly lower wind resistance, resulting in reduced fan operation and investment costs.

(4) High Welding Fusion Rate

Thanks to the unique zigzag structure of the patented H fins, the weld fusion rate between fins and steel pipes can exceed 98%, ensuring an exceptional heat transfer coefficient for H-finned tubes.

(5) Compact and Efficient Design

The H finned tube offers a substantial heating area per unit length, approximately 7.8 times that of smooth tubes. Enhanced welding quality is achieved through argon arc welding, far superior to manual welding techniques. With significant reductions in equipment size and weight, the investment in heat transfer surfaces is minimized, offering users greater flexibility in equipment installation and space utilization.

(6) Vibration and Noise Reduction

Due to its innovative structural design, the H finned tube possesses the attributes of a muffler, allowing the equipment to function effectively as a noise suppressor.

(7) Easy Installation, Operation, and Maintenance

For installation, simply connect the equipment to the exhaust gas outlet of HFO engine units, and it will be ready for seamless operation. Equipped with a check door, the exhaust gas boiler allows for cleaning cycle determination based on actual conditions, ensuring optimal heat transfer and extending operational lifespan.
