Product Description

Description of H-fin Boiler Finned Tubes

The cutting-edge heat transfer technology of our boilers leverages the H-shaped fin tubes, ingeniously welding two precise steel arcs symmetrically onto the raw tube. This innovative design forms fins that remarkably resemble the letter 'H', thus the name H-finned tube. The H-finned tube boasts rectangular fins that are nearly square, stretching about twice the length of the tube's diameter, significantly amplifying the heating surface. Ingeniously crafted, the H-finned tube can be transformed into a 'double H' finned tube featuring a robust double-tube structure, making it ideal for extended rows of tubes.

The H fin tube excels in reclaiming gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. It substantially boosts fuel efficiency by strategically positioning the heat exchange element at the flue's system tail.

Detail

Our H-type finned tube heat exchanger elements shine with their exceptional heat transfer capability, superior self-cleaning attributes, and proficiency in flue gas waste heat recovery, crucial for boiler renovations. The convective heat transfer coefficient increases with fin pitch while decreasing with fin height and width, optimizing thermal performance. The overall heat transfer capacity is intricately linked to fin efficiency, the convective heat transfer coefficient, and the finned ratio, promising optimal performance. As fin height and width rise, so does the pressure drop, an essential consideration in design for optimal efficiency.

To enhance heat exchange efficiency and maximize surface heat transfer, H-type finned tubes have gained extensive application in boilers and waste heat recovery. H-type finned tubes are predominantly developed from rectangle finned tubes, embodying advanced design and engineering. Thanks to their distinct groove structure on the fin surface, H-type finned tubes deliver outstanding anti-wear and anti-fouling performance.

We offer custom solutions tailored to our clients' needs, designing and manufacturing H-fin tubes that are safe, reliable, and efficient.

The Economizer H Type Extruded Fin Tube is available in diverse materials, such as copper and stainless steel, to meet various requirements. The low fin design ensures the tube is compact and lightweight, ideal for installations where space is at a premium.

This versatile finned tube is perfect for air coolers, radiators, and other heat exchanger applications, ensuring broad utility. Our expert manufacturing process ensures precise dimensions and tight tolerances, guaranteeing seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the pivotal element within the exhaust gas boiler's heat exchange system, showcasing distinct benefits that set it apart.

(1) Superior Wear Resistance

The H-finned tube heat exchanger is meticulously aligned, with H fins creating multiple small zones that ensure even air distribution. Unlike staggered smooth tubes or spiral finned exchangers, this design significantly extends wear life by a factor of 3 to 4.

(2) Minimized Fouling

Fouling typically occurs on the dorsal and windward sides of the tube. The staggered tube configuration facilitates easier flushing of the tube bundle, resulting in reduced fouling on the backside. At optimal wind speeds, it boasts an excellent self-cleaning capability. Straight channels formed on the sides of the H finned tube enable efficient soot removal, especially when a soot blower is employed.

(3) Lower Exhaust Gas Resistance

The straight channels created by H fins and the spiral angle of spiral fins guide airflow effectively, reducing the likelihood of fouling and minimizing flue resistance compared to traditional designs. Thus, opting for H-finned tubes reduces wind resistance, leading to lower fan operation and investment costs.

(4) High Weld Fusion Rate between Fins and Steel Pipe

Thanks to the patented zigzag configuration of H fins, the fusion rate between fins and steel pipes reaches an impressive 98% or more, ensuring optimal heat transfer efficiency.

(5) Compact Design with Superior Heat Efficiency

The H finned tube provides a significant heating area per unit length, 7.8 times that of a smooth tube. Argon arc welding elevates the quality of butt welds far beyond manual methods. This streamlined design drastically cuts down equipment size and weight, reducing investment and offering users greater flexibility in equipment installation.

(6) Vibration and Noise Mitigation

The structural design and unique features of the H finned tube imbue it with muffling capabilities, enabling the equipment to also serve as a noise reducer.

(7) Easy Installation, Operation, and Maintenance

Installation is simplified; just connect the equipment to the exhaust gas outlet of HFO engine units for immediate operation. The exhaust gas boiler includes a check door for determining the cleaning cycle based on actual conditions, ensuring prolonged heat transfer efficiency and extending operational lifespan.
