Product Description

Description of H-fin Boiler Finned Tubes

The innovative heat transfer tube in our boilers features H-shaped fin tubes. This design involves welding two arcuate steel pieces symmetrically onto the raw tube, creating a series of fins (ribs) that resemble the letter 'H'. Hence, they are aptly named H-finned tubes, delivering enhanced thermal efficiency. The fins on the H-finned tube are remarkably crafted into a rectangular, almost square shape. They extend the heating surface significantly, with each fin measuring approximately twice the diameter of the tube, thereby optimizing heat transfer capabilities. For applications requiring greater rigidity, the H-finned tube can be transformed into a 'double H' finned tube, which utilizes a double-tube structure. This robust design is perfect for longer tube rows, ensuring stability and efficiency.

H fin tubes are engineered to recover gas waste heat from power station boilers, industrial boilers, industrial kilns, ship power plants, and more. They are strategically positioned at the tail of system flues, significantly enhancing fuel utilization and overall heat exchange efficiency.

Detail

H-type finned tube heat exchanger elements boast a high heat transfer capacity, superior self-cleaning abilities, and are instrumental in flue gas waste heat recovery during boiler renovations. The convective heat transfer coefficient increases with the fin pitch, but decreases as fin height and width grow. This relationship is crucial in optimizing heat exchanger design. The total heat transfer capacity is influenced by several factors, including fin efficiency, convective heat transfer coefficient, and the finned ratio, highlighting the importance of balanced design. As fin height and width increase, so does the pressure drop, suggesting a need for careful design considerations to maintain optimal system performance.

H-type finned tubes have become a staple in modern boilers and waste heat recovery systems, thanks to their exceptional heat exchange efficiency and extended surface heat transfer capabilities. Derived primarily from rectangular finned tubes, H-type finned tubes offer a unique solution for enhanced heat transfer applications. Thanks to their unique grooved structure, these H-type finned tubes boast excellent anti-wear and anti-fouling properties, ensuring long-lasting performance and minimal maintenance.

Our products are tailored to meet customer specifications and situational needs. We focus on designing and manufacturing H-fin tubes that are safe, reliable, and efficient, accommodating a wide range of industrial applications.

The Economizer H-Type Extruded Fin Tube is versatile, available in materials such as copper and stainless steel, to meet diverse operational requirements. Its low fin design is ingeniously compact and lightweight, making it an excellent choice for installations where space is at a premium.

This finned tube is expertly suited for use in air coolers, radiators, and a variety of heat exchanger applications, providing unmatched versatility. Our precision manufacturing process ensures that each finned tube is produced with exact dimensions and tight tolerances, allowing for seamless integration into any existing system.

Advantages of H-finned tube:

Boasting significant advantages, the H-finned tube stands as the cornerstone of heat exchange in exhaust gas boilers.

(1) Superb Wear Resistance

Ingeniously arranged in line, the H-finned tube heat exchanger features fins that create multiple small spaces, ensuring uniform airflow. Compared to traditional staggered or spiral finned heat exchangers, it offers wear life that is 3-4 times higher under similar conditions.

(2) Minimized Fouling

Fouling typically occurs on the dorsal and windward sides of the tube. Thanks to its staggered tube arrangement, easy flushing of the tube bundle is facilitated, leading to reduced fouling on the backside. With optimal wind speeds, it boasts an excellent self-cleaning function. The H-finned tube forms straight channels on both sides, optimizing soot removal when used with a soot blower.

(3) Lower Exhaust Gas Resistance

Straight channels formed by the H fins, combined with the spiral fin's airflow direction, minimize fouling and flue resistance compared to traditional spiral fins. Thus, integrating H-finned tubes reduces wind resistance, lowers fan operational costs, and cuts down on investment.

(4) Outstanding Welding Fusion Rate

The unique zigzag structure (patented) of the H fins facilitates an impressive weld fusion rate of 98% or more with steel pipes, ensuring superior heat transfer.

(5) Compact and Highly Efficient

The large heating area per unit length is 7.8 times that of smooth tubes. Butt welds achieved through argon arc welding significantly enhance quality, surpassing manual methods. With reduced size and weight, the investment in equipment is lowered, offering users ample space for installation.

(6) Shock Absorption and Noise Reduction

Its structural design and the unique characteristics of the H finned tube allow it to act as a muffler, effectively reducing noise.

(7) Ease of Installation, Operation, and Maintenance

Installation requires merely connecting to the exhaust gas outlet of HFO engine units. Once connected, the equipment is ready for operation. Featuring a check door, the exhaust gas boiler allows easy determination of cleaning cycles based on actual usage, ensuring optimal heat transfer and extending its lifespan.
