Product Description

A Comprehensive Overview of H-Fin Boiler Finned Tubes

The cutting-edge heat transfer tube of the boiler proudly incorporates H-shaped fin tubes. This innovative design involves the precise welding of two steel pieces, elegantly with arcs at the center, symmetrically onto the raw tube to craft unique fins (ribs). The impressive front appearance closely resembles the letter 'H', earning its name as the renowned H-finned tube. Distinguished by their rectangular shape, the fins of the H-finned tube are nearly square, extending approximately twice the tube's diameter. This design provides an increased heating surface, optimizing efficiency. The H-finned tube showcases versatility as it can be masterfully crafted into a 'double H' finned tube with a dual-tube configuration. Its robust structure proves ideal for application in extended tube rows, offering superior durability.

H fin tubes are engineered to reclaim gas waste heat from power station boilers, industrial boilers, industrial kilns, and marine power plants. They significantly enhance fuel utilization efficiency, with the heat exchange element strategically positioned at the system flue's tail.

Detailed Insights into H-Finned Tube Technology

H-type finned tube heat exchanger elements are engineered for optimal heat transfer capacity. Their superior self-cleaning properties and impressive ability to recover flue gas waste heat make them indispensable in boiler renovations. The convective heat transfer coefficient is directly proportional to fin pitch, while inversely related to fin height and width, ensuring precise thermal management. The overall heat transfer capacity is intricately linked to fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring unparalleled performance. The pressure drop is an essential factor to consider, as it rises with increased fin height and width, impacting the system's efficiency.

With a focus on maximizing heat exchange efficiency and broadening the surface heat transfer area, H-type finned tubes have become pivotal in modern boilers and waste heat recovery systems. H-type finned tubes have evolved predominantly from the innovative rectangle finned tube designs, showcasing their advanced engineering. Thanks to their distinct groove structure on the fin surface, H-type finned tubes offer remarkable anti-wear and anti-fouling performance, ensuring longevity and reliability.

Our product line can be expertly customized to meet specific client requirements, ensuring safe, reliable, and highly efficient H-fin tube designs and manufacturing.

The Economizer H Type Extruded Fin Tube is available in diverse materials, such as copper and stainless steel, to accommodate varying application needs. The low fin design guarantees a compact, lightweight solution, making it an ideal choice for installations where space is at a premium.

This versatile finned tube is perfectly suited for applications in air coolers, radiators, and other heat exchanger systems, offering unmatched performance. Our meticulous manufacturing process ensures precision dimensions and tight tolerances, facilitating flawless integration into existing systems, enhancing operational efficiency.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the cornerstone of heat exchange within an entire exhaust gas boiler, delivering exceptional performance through its numerous advantages.

(1) Excellent wear resistance

The innovative design of the H-finned tube heat exchanger aligns the tubes methodically, with H fins creating multiple small areas. This arrangement promotes balanced air flow, achieving wear resistance that surpasses smooth tube exchangers with staggered layouts and spiral finned exchangers by 3 to 4 times under comparable conditions.

(2) Fouling reduced

Fouling typically develops on the dorsal and windward sides of the tube. Thanks to the staggered tube arrangement, the tube bundle is easily flushed, minimizing fouling on the back side. With an optimal wind speed, it exhibits an excellent self-cleaning capability. Straight channels formed on each side of the H finned tube effectively handle soot, achieving optimal results when using a soot blower.

(3) Reduce the resistance of exhaust gas

H fins craft straight channels on both sides, while the spiral angle of spiral fins directs airflow. Thus, H fins experience less fouling and lower flue resistance compared to their spiral counterparts. Hence, implementing H-finned tubes can significantly minimize wind resistance and reduce both fan operation costs and investment expenses.

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

Boasting a patented zigzag structure, the H fins achieve a weld fusion rate with steel pipes of 98% or more, ensuring an excellent heat transfer coefficient for these sophisticated tubes.

(5) Compact structure, high heat efficiency

Offering a substantial heating area per unit length, the H finned tube's capacity is 7.8 times that of smooth tubes. With all butt welds executed via argon arc welding, welding quality markedly surpasses that of manual welding. With substantial reductions in both equipment size and weight, this technology significantly lowers investment costs while providing users with increased installation space, all on the same heat transfer surface.

(6) Shock-proof and noise reduced

Thanks to the ingenious structural design and characteristics of the H finned tube, it embodies the features of a muffler, thereby allowing the equipment to also serve as a noise reduction device.

(7) Convenient for installation, operation and maintenance

Installation is streamlined, requiring only connection to the exhaust gas outlet of HFO engine units to begin normal operation. The exhaust gas boiler includes a check door to determine cleaning cycles based on real-time conditions, thus optimizing heat transfer and extending operational life.
