Product Description

Description of H-fin boiler Finned Tubes

The heat transfer tube of the boiler gracefully incorporates the H-shaped fin tubes, ingeniously welding two pieces of steel with arcs in the center, symmetrically onto the raw tube to craft the fins (ribs). The resulting profile resembles the letter 'H,' thus earning the name H-finned tube. H-finned tubes feature rectangular, nearly square fins, extending approximately twice the tube's diameter, beautifully enhancing the heating surface and optimizing heat exchange. Ingeniously designed, the H-finned tube can transform into a 'double H' finned tube of double-tube configuration, offering a robust structure well-suited for longer tube rows.

Our H fin tubes excel in capturing gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants. They dramatically boost fuel utilization and are strategically placed at the end of the system flue to maximize heat exchange.

Detail

The H-type finned tube heat exchanger elements are renowned for their exceptional heat transfer capacity, outstanding self-cleaning properties, and remarkable ability to recover flue gas waste heat, particularly advantageous in boiler renovations. The convective heat transfer coefficient is finely tuned, being directly proportional to fin pitch but inversely related to fin height and width, showcasing the intricacies of design. The comprehensive heat transfer capacity intricately depends on fin efficiency, convective heat transfer coefficient, and the nuanced finned ratio. Pressure drop intricately increases with enhancements in fin height and width, a critical consideration in design.

Recently, H-type finned tubes have gained widespread acclaim and application in boilers and waste heat recovery systems, significantly boosting heat exchange efficiency and extending surface transfer capabilities. Derived from rectangle finned tubes, H-type finned tubes have evolved into a sophisticated solution for enhanced thermal performance. Thanks to their exceptional groove structure on the fin surface, H-type finned tubes boast superior anti-wear and anti-fouling capabilities, setting them apart in durability and efficiency.

Our products can be tailored to meet our customers' specific requirements. We design and manufacture H-fin tubes that are synonymous with safety, reliability, and efficiency.

The versatile Economizer H Type Extruded Fin Tube is available in a range of materials, including copper and stainless steel, to meet diverse operational demands. The low fin design ensures a compact and lightweight profile, making it the perfect choice for installations where space is at a premium.

Ideal for air coolers, radiators, and a plethora of heat exchanger applications, this finned tube is the embodiment of versatility. Our expert manufacturing process assures precise dimensions and tight tolerances, allowing for the seamless integration of our finned tubes into any existing system framework.

Product Details

Advantages of the H-Rectangular Finned Tube:

The H-finned tube serves as the cornerstone of heat exchange efficiency in exhaust gas boilers, boasting unparalleled benefits that elevate its performance.

(1) Superior Wear Resistance

Ingeniously designed, the H finned tube heat exchanger features a linear arrangement where H fins segment space into smaller zones, ensuring uniform airflow. Compared to staggered or spiral finned heat exchangers, it offers wear resistance that's 3-4 times higher under identical conditions.

(2) Minimized Fouling

Fouling typically manifests on both the dorsal and windward sides of the tube. Thanks to its staggered tube arrangement, the bundle is easily flushed, significantly reducing fouling on the back side. At optimal wind speeds, it exhibits excellent self-cleaning capabilities. The straight channels formed alongside the H fins enhance soot removal efficiency, especially when paired with a soot blower, achieving optimal soot clearance.

(3) Lowered Exhaust Gas Resistance

With the creation of straight channels by H fins, and spiral fins directing airflow, H fins outperform in reducing flue resistance compared to spiral fins prone to fouling. The application of H fins leads to diminished wind resistance, thus slashing fan operation and investment costs.

(4) High Welding Fusion Rate for Fins and Steel Pipes

Featuring a patented unique zigzag structure, H fins achieve a weld fusion rate exceeding 98%, ensuring exceptional heat transfer efficiency in H-finned tubes.

(5) Compact Design and High Heat Efficiency

Offering a heating area 7.8 times larger per unit length than smooth tubes, and utilizing argon arc welding for superior weld quality, the H finned tube maximizes efficiency. This reduction in size and weight translates to decreased equipment costs and provides ample installation space, thus offering great value to users.

(6) Shock-Proof and Noise Reduction

The structural ingenuity of the H finned tube, along with its device design, naturally integrates muffler characteristics, enabling the equipment to function quietly.

(7) Ease of Installation, Operation, and Maintenance

Installation is simplified: just connect the equipment to the exhaust gas outlet of HFO engine units for seamless operation. Equipped with a check door, the exhaust gas boiler allows for tailored cleaning cycles based on real-time conditions, ensuring prolonged heat transfer efficacy and longevity.
