Product Description

Description of H-fin boiler Finned Tubes

The heat transfer tube of the boiler is ingeniously designed using H-shaped fin tubes. This innovative design involves welding two pieces of meticulously curved steel symmetrically onto the raw tube, creating distinct fins (or ribs). The front profile mirrors the letter 'H,' thus earning it the name H-finned tube. The H-finned tube boasts rectangular, nearly square fins, with a length approximately twice the diameter of the tube, ingeniously extending the heating surface for superior thermal performance. Our H-finned tube can also be crafted into a versatile 'double H' finned tube with a double-tube configuration. This robust structure is ideal for applications requiring a longer alignment of tubes, enhancing rigidity and performance.

The H fin tube shines in energy recovery, capturing gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants, significantly elevating fuel efficiency. The heat exchange element is strategically positioned at the system flue's tail.

Detail

H-type finned tube heat exchanger elements excel in heat transfer, offering exceptional self-cleaning capabilities while effectively reclaiming flue gas waste heat during boiler upgrades. The convective heat transfer coefficient has a direct correlation with fin pitch, while being inversely related to fin height and width, optimizing thermal dynamics. Integrated heat transfer capacity is intricately linked to fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring optimal thermal exchange. An increase in fin height and width results in a corresponding rise in pressure drop, a critical consideration for system design.

To enhance heat exchange efficiency and broaden heat transfer surfaces, H-type finned tubes have become a staple in modern boilers and waste heat recovery systems, proving their worth in various applications. H-type finned tubes are primarily derived from the classic rectangle finned tubes, maintaining traditional strengths while offering modern efficiencies. Thanks to their distinct groove structure on the fin surface, H-type finned tubes boast remarkable resistance to wear and fouling, ensuring long-lasting performance.

Our offerings can be tailored to meet specific customer requirements. We are committed to designing and manufacturing H-fin tubes that are safe, reliable, and efficient, perfectly aligning with client demands.

The Economizer H Type Extruded Fin Tube is crafted from a variety of materials, including copper and stainless steel, to address diverse operational needs. The low fin design guarantees compactness and lightness, making it the perfect choice for installations where space is at a premium.

This versatile finned tube is a perfect fit for air coolers, radiators, and a wide array of heat exchanger applications. Our skilled manufacturing process ensures precise dimensions and tight tolerances, facilitating seamless integration into existing thermal systems.

Product Details

Advantages of H-finned tube:

The H-finned tube serves as the cornerstone heat exchange element within the entire exhaust gas boiler system, proudly boasting several remarkable advantages that set it apart.

(1) Excellent wear resistance

Uniquely, the H finned tube heat exchanger is arranged in a linear formation, with H fins strategically separating the space into numerous small areas. This design effectively equalizes airflow, offering superior wear resistance compared to smooth tube heat exchangers with staggered arrangements and spiral finned heat exchangers. Under identical conditions, the wear life of the H finned tube surpasses others by an impressive 3 to 4 times.

(2) Fouling reduced

Fouling tends to develop on both the dorsal and windward sides of the tube. The staggered arrangement of the tubes facilitates easy cleaning of the tube bundle, resulting in significantly reduced fouling on the back side. Additionally, with the right wind speed, the H-finned tube exhibits an exceptional self-cleaning capability. Straight channels formed on both sides of the H finned tube enhance soot management, achieving optimal soot removal when using a soot blower.

(3) Reduce the resistance of exhaust gas

The H fins create straight channels alongside, while the spiral angle of spiral fins directs the airflow. This design ensures the H fins are less prone to fouling and achieve lower flue resistance compared to spiral fins. Thus, incorporating H-finned tubes notably diminishes wind resistance, leading to reduced operational and investment costs for fans.

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

Boasting an exclusive zigzag structure (patented), the H fins achieve a weld fusion rate with steel pipes as high as 98% or more, ensuring outstanding heat transfer efficiency in H-finned tubes.

(5) Compact structure, high heat efficiency

With a large heating area per unit length, the H finned tube is 7.8 times more efficient than smooth tubes. All butt welds are meticulously executed via argon arc welding, significantly enhancing welding quality over manual methods. The equipment's size and weight are substantially reduced, leading to a significant decrease in equipment investment while offering users ample space for equipment installation within the same heat transfer surface area.

(6) Shock-proof and noise reduced

Thanks to its innovative structural design and the inherent characteristics of the H finned tube, the equipment also serves as an effective muffler, providing a quieter operation.

(7) Convenient for installation, operation and maintenance

During installation, simply connect the equipment to the exhaust gas outlet of the HFO engine units, and it seamlessly transitions into normal operation; The exhaust gas boiler features a check door, allowing for cleaning cycle determination based on real-time conditions, ensuring optimal heat transfer efficiency and extended service life.
