Product Description

Description of H-fin boiler Finned Tubes

Our boiler heat transfer tube is ingeniously crafted with H-shaped fin tubes. By expertly welding two pieces of steel, each featuring elegant arcs, symmetrically onto the raw tube, we create distinctive fins, or ribs, resembling the uppercase letter 'H.' This innovative design gives rise to the renowned H-finned tube. The design of our H-finned tubes features rectangular fins, nearly square, stretching to a length approximately twice the tube's diameter. This provides an extended heating surface for enhanced performance. For increased robustness, the H-finned tube can be transformed into a "double H" finned tube with a dual-tube configuration. Its remarkable rigidity suits it perfectly for longer tube arrangements.

Our H fin tube excels in recovering gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants. It significantly enhances fuel utilization, with the heat exchange element strategically placed at the system flue's tail.

Detail

H-type finned tube heat exchanger elements are lauded for their high heat transfer capacity, superior self-cleaning properties, and ability to recover flue gas waste heat, especially in boiler renovations. The convective heat transfer coefficient directly correlates with fin pitch but inversely relates to fin height and width, optimizing thermal performance. The amalgamation of fin efficiency, convective heat transfer coefficient, and finned ratio governs the integrated heat transfer capacity. A remarkable increase in pressure drop is observed with rising fin height and width, indicating a balance between dimensions and efficiency.

H-type finned tubes have become increasingly popular in recent years, favored for their capacity to enhance heat exchange efficiency and extend surface heat transfer, especially in boilers and waste heat recovery. Uniquely derived from rectangular finned tubes, H-type finned tubes represent an evolution of design and efficiency. Thanks to an exclusive groove structure on the fin surface, H-type finned tubes boast exceptional anti-wear and anti-fouling properties, ensuring durability and longevity.

Our bespoke solutions allow for product modifications tailored to meet customer-specific requirements. We design and manufacture H-fin tubes that are synonymous with safety, reliability, and efficiency.

The Economizer H Type Extruded Fin Tube is available in a diverse range of materials, including copper and stainless steel, catering to a multitude of applications and requirements. The low fin design stands out for its compactness and lightweight nature, making it an ideal choice for installations where space is at a premium.

This versatile finned tube is perfectly suited for air coolers, radiators, and a variety of other heat exchanger applications, offering unmatched adaptability. Manufactured with precision, this product guarantees exact dimensions and tight tolerances. This ensures seamless integration into existing systems for optimal performance.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the cornerstone of the heat exchange process in exhaust gas boilers, offering a range of unparalleled advantages that set it apart.

(1) Exceptional Wear Resistance

The H finned tube heat exchanger is meticulously arranged in line, with H fins creating distinct small compartments that harmonize air flow. In comparison to other configurations like staggered or spiral finned designs, the H-finned tube boasts a wear life that is 3 to 4 times longer, ensuring durability and reliability.

(2) Reduced Fouling

Fouling typically forms on the dorsal and windward sides of tubes, but the H-finned design effectively minimizes this build-up. The staggered configuration facilitates easy flushing of the tube bundle, significantly reducing fouling on the back side. An optimum wind speed enables the H-finned tube to exhibit excellent self-cleaning abilities. The straight channels on either side of the H finned tube enhance soot removal, especially when employing a soot blower, achieving superior cleaning results.

(3) Lower Exhaust Gas Resistance

H fins craft straight channels that streamline airflow, unlike spiral fins that add resistance. The H-finned tubes excel in reducing flue resistance, optimizing airflow and efficiency. Employing H-finned tubes decreases wind resistance, thus cutting down on fan operation costs and initial investment, leading to substantial savings.

(4) High Fusion Rate of Fins and Steel Pipe Welding

Thanks to the distinctive zigzag structure of the H fins, the weld fusion rate with steel pipes achieves an impressive 98% or higher, guaranteeing an exceptional heat transfer coefficient.

(5) Compact Structure and High Heat Efficiency

With a heating area per unit length 7.8 times greater than that of smooth tubes, the H finned tube maximizes efficiency. Argon arc welding enhances weld quality beyond manual methods, minimizing weight and size while amplifying effectiveness. This streamlined design significantly cuts down equipment investment and offers more space for users during installation, enhancing both functionality and convenience.

(6) Vibration and Noise Reduction

The innovative structural design and characteristics of the H finned tube enable it to function as an effective muffler, reducing both vibrations and noise for a smoother operation.

(7) Easy Installation, Operation, and Maintenance

Installation is straightforward, requiring only a connection to the exhaust gas outlet of HFO engine units for seamless operation. Equipped with a check door, the exhaust gas boiler allows for customized cleaning cycles based on actual conditions, ensuring optimal heat transfer and extending the equipment's lifespan.
