Product Description

Description of H-fin boiler Finned Tubes

Crafted with precision, the heat transfer tube of the boiler ingeniously incorporates H-shaped fin tubes. This involves welding two symmetrical steel arcs onto the raw tube, creating distinctive fins that resemble the letter "H". This innovative design is aptly named the H-finned tube. The H-finned tube features remarkable rectangular fins, nearly square in shape. These fins extend around twice the diameter of the core tube, significantly enhancing the heating surface area. For added robustness, the H-finned tube can be transformed into a "double H" finned tube, integrating two tubes. This structural enhancement offers excellent rigidity, making it suitable for extended tube arrays.

H fin tubes are expertly utilized to reclaim gas waste heat across various applications, including power station boilers, industrial boilers, kilns, and marine power systems. This significantly boosts fuel efficiency, positioning the heat exchange elements strategically at the flue's tail.

Detail

H-type finned tube heat exchanger components showcase remarkable heat transfer capabilities. Their superior self-cleaning characteristics and efficient flue gas waste heat recovery make them ideal for boiler upgrade projects. The convective heat transfer coefficient increases with fin pitch while decreasing with fin height and width, illustrating a delicate balance for optimal performance. The comprehensive heat transfer capacity is intricately tied to fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring maximum energy utilization. As the fin height and width increase, so does the pressure drop, a critical factor to consider in design and application.

In recent years, H-type finned tubes have become increasingly prevalent in boilers and waste heat recovery systems, thanks to their exceptional ability to enhance heat exchange efficiency and surface heat transfer. H-type finned tubes are primarily evolved from rectangle finned tubes, retaining their beneficial properties while offering improved performance. Featuring a specialized grooved surface, H-type finned tubes deliver outstanding anti-wear and anti-fouling performance, setting them apart in demanding environments.

Tailored to meet specific customer needs, our H-fin tubes are engineered to be safe, reliable, and efficient, showcasing our commitment to innovative design and manufacturing excellence.

Our Economizer H Type Extruded Fin Tube is crafted in diverse materials like copper and stainless steel, providing solutions for various industry-specific requirements. Designed with a low fin profile, these tubes are compact and lightweight, making them perfect for installations where space is at a premium.

This versatile finned tube finds its application in air coolers, radiators, and a wide range of heat exchanger operations, demonstrating its adaptability. Our meticulous manufacturing process ensures precision in dimensions and tight tolerances, facilitating seamless integration into pre-existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands out as the primary heat exchange component in the exhaust gas boiler system, delivering paramount advantages that set it apart.

(1) Exceptional Wear Resistance

The H-finned tube heat exchanger is precisely aligned in a straight configuration. Its unique H fins strategically divide the space into smaller zones, facilitating an even airflow distribution. Compared to smooth tube exchangers with staggered designs or spiral finned variants, the H-finned tube boasts an impressive wear lifespan, extending 3 to 4 times longer under similar conditions.

(2) Significantly Reduced Fouling

Fouling formation typically occurs on the dorsal and windward sides of tubes. With a staggered tube arrangement, the bundle is easily flushed, reducing fouling on the back side. This design enables a remarkable self-cleaning capability at optimal wind speeds. The straight channels formed on both sides of the H-finned tube efficiently manage soot deposits, ensuring the best soot removal when using a soot blower.

(3) Minimized Exhaust Gas Resistance

With straight channels on either side formed by the H fins, complemented by the spiral angle directing airflow, the H-finned tube minimizes flue resistance compared to typical fins prone to fouling. Consequently, employing the H-finned tube lowers wind resistance, curtailing fan operation and reducing associated investment costs.

(4) Superior Weld Fusion Rate

Featuring a patented zigzag H fin structure, this design achieves a remarkable weld fusion rate exceeding 98% between fins and steel pipes, ensuring an optimal heat transfer coefficient.

(5) Compact and Highly Efficient Structure

The H-finned tube offers an expansive heating area per unit length, 7.8 times greater than that of smooth tubes. Utilizing argon arc welding for butt welds, it surpasses manual welding in quality. The equipment is lightweight and compact, significantly reducing investment costs while offering users more space for installation, without compromising heat transfer efficiency.

(6) Vibration and Noise Reduction

With a thoughtfully designed structure, the H-finned tube integrates muffler characteristics, enabling the equipment to also function as an effective noise dampener.

(7) Simplified Installation, Operation, and Maintenance

During installation, simply connect the equipment to the exhaust gas outlet of HFO engine units to commence regular operations. The exhaust gas boiler is equipped with an inspection door, allowing for cleaning cycle determination based on actual conditions, ensuring optimal heat transfer and extending operational life.
