Product Description

Description of H-fin boiler Finned Tubes

Experience the advanced engineering of our H-shaped fin tubes. These innovative heat transfer tubes for boilers are crafted by symmetrically welding two steel pieces with precise arcs onto the raw tube, creating distinctive fins reminiscent of the letter 'H'. Hence, they are aptly named H-finned tubes. Our meticulously designed H-finned tubes boast rectangular, nearly square fins that are approximately twice the tube's diameter in length, effectively expanding the heating surface area for enhanced performance. For applications requiring robust support, the H-finned tube can be configured into a 'double H' finned tube with a double-tube structure, offering outstanding rigidity and suitability for extended rows of tubes.

The H fin tube excels at harnessing gas waste heat recovery from power station boilers, industrial boilers, kilns, and marine power plants. By strategically placing the heat exchange element at the system flue's tail, it significantly boosts fuel utilization and efficiency.

Detail

Engineered for excellence, our H-type finned tube heat exchanger elements deliver exceptional heat transfer capabilities, superior self-cleaning attributes, and are perfectly suited for flue gas waste heat recovery, particularly in boiler upgrades. The convective heat transfer coefficient is directly related to the fin pitch while inversely correlated with both the fin height and width, showcasing a delicate balance for optimal performance. The integrated heat transfer capacity of our finned tubes is intricately linked to fin efficiency, convective heat transfer coefficient, and the finned ratio, ensuring superior thermal performance. As the fin height and width increase, so does the pressure drop, requiring precise engineering for efficient operational dynamics.

In the pursuit of maximizing heat exchange efficiency and surface heat transfer, H-type finned tubes have emerged as a popular choice for modern boilers and waste heat recovery systems. Our H-type finned tubes are primarily derived from traditional rectangular finned tubes, offering enhanced adaptation for diverse thermal applications. Thanks to their unique groove structure on the fin surface, H-type finned tubes boast remarkable resistance against wear and fouling, extending their operational lifespan.

At Cangzhou Datang Steel Pipe Co., Ltd., we are committed to customizing our products to meet specific customer needs. Our H-fin tubes stand out for their safety, reliability, and efficiency.

Our Economizer H Type Extruded Fin Tube is available in versatile materials such as copper and stainless steel, designed to meet various technical requirements.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the centerpiece of heat exchange in exhaust gas boilers, boasting remarkable advantages that set it apart.

(1) Unmatched Wear Resistance

Engineered for durability, the H-finned tube heat exchanger is strategically arranged in a linear formation. Unlike its smooth tube and spiral counterparts, the H fins effectively partition the space into smaller zones, promoting a balanced airflow. This ingenious design not only extends wear life by a factor of 3 to 4 times under similar conditions but also ensures longevity.

(2) Minimized Fouling

Fouling typically occurs on the dorsal and windward sides of tubes. The staggered tube configuration facilitates efficient flushing of the tube bundle, significantly reducing fouling on the back side. At optimal wind speeds, the system exhibits impressive self-cleaning capabilities. The H-finned tube creates straight channels on both sides, optimizing soot management. When paired with a soot blower, it achieves unparalleled soot removal efficiency.

(3) Reduced Exhaust Gas Resistance

Featuring straight channels formed by the H fins, complemented by the spiral angle steering airflow direction, the H fins exhibit less fouling and lower flue resistance compared to spiral fins. By integrating H-finned tubes, wind resistance is minimized, leading to reduced fan operation demands and decreased investment costs.

(4) High Welding Fusion Rate

Thanks to the patented zigzag structure of the H fins, the weld fusion rate with steel pipes reaches an impressive 98% or higher, ensuring exceptional heat transfer coefficients for the H-finned tubes.

(5) Compact and Highly Efficient Structure

Boasting a substantial heating area per unit length, the H-finned tube is 7.8 times more efficient than a smooth tube. With all butt welds executed using superior argon arc welding, the welding quality significantly surpasses traditional manual methods. The optimized size and reduced weight of the equipment not only cut down on investment but also offer users more space for equipment installation, all while maintaining an equivalent heat transfer surface.

(6) Vibration and Noise Control

The H-finned tube's structural design integrates muffler-like characteristics, enabling the equipment to function effectively as a noise reducer.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward, requiring only the connection of the equipment to the exhaust gas outlet of HFO engine units for seamless operation; Equipped with an inspection door, the exhaust gas boiler allows for cleaning cycles to be tailored based on actual conditions, enhancing heat transfer efficiency and extending operational life.
