Product Description

Discover the Superior H-Fin Boiler Finned Tubes

Envision unparalleled heat transfer with the H-shaped fin tubes of this innovative boiler. Crafted by symmetrically welding two elegantly curved steel pieces to the raw tube, these fins resemble the letter 'H'. Hence, they're aptly named H-finned tubes, revolutionizing heat efficiency. Boasting rectangular, nearly square fins, the H-finned tube extends the heating surface with a length approximately twice the tube’s diameter, elevating heat transfer capabilities to new heights. With an option to transform into a 'double H' finned tube featuring a dual-tube design, this structure provides remarkable rigidity, making it perfect for extended rows of tubes.

The H fin tube is engineered to reclaim gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. It significantly enhances fuel utilization rate and is strategically placed at the system flue tail for optimal heat exchange.

Detailed Insights

The H-type finned tube excels in heat transfer with superior self-cleaning features, offering exceptional flue gas waste heat recovery, particularly during boiler retrofits. Convective heat transfer coefficient intricately links to fin pitch, while inversely tied to fin height and width, highlighting a balance of precision in design. Overall heat transfer prowess hinges on fin efficiency, the convective heat transfer coefficient, and the finned ratio, showcasing the intricate engineering beneath. Experience a rise in pressure drop as fin height and width increase, balancing performance and efficiency.

Widely adopted in boiler and waste heat recovery, H-type finned tubes enhance heat exchange efficiency with their expanded surface design. Rooted mainly in rectangle finned tubes, the H-type design stands out for its innovative use and efficiency. Thanks to a unique groove structure on the fin surface, H-type finned tubes excel in anti-wear and anti-fouling, ensuring longevity and performance.

We offer customizable solutions to meet specific customer needs, producing safe, reliable, and efficient H-fin tubes tailored for every situation.

Our Economizer H Type Extruded Fin Tube comes in materials like copper and stainless steel, addressing diverse application requirements with versatility. The low fin design prioritizes compactness and light weight, making it perfect for installations where space is at a premium.

Ideal for air coolers, radiators, and a variety of heat exchanger applications, this finned tube underscores versatility. Precision engineering ensures tight tolerances and exact dimensions, facilitating seamless integration with existing systems, thanks to its meticulous manufacturing process.

Product Details

Compelling Advantages of the H-Finned Tube:

The H-finned tube serves as the primary heat exchange element within the exhaust gas boiler system. This innovative component offers an array of incredible benefits.

(1) Superior Wear Resistance

The H-finned tube heat exchanger is meticulously aligned in rows, creating multiple small air compartments due to the H fins. These compartments help in balancing air flow, providing an impressive wear life that surpasses traditional smooth tube heat exchangers, staggered arrangements, and spiral finned heat exchangers by 3 to 4 times under identical conditions.

(2) Minimized Fouling

Fouling tends to occur on the dorsal and windward sides of the tube. The staggered configuration facilitates the flushing of tube bundles, resulting in significantly less fouling on the rear side. Boasting an effective self-cleaning capability when operated at optimal wind speeds, it maintains cleanliness effortlessly. By forming straight channels on the sides of the H-finned tube, it efficiently directs soot for optimal removal, especially when used in conjunction with a soot blower.

(3) Reduced Exhaust Gas Resistance

The straight channels crafted by the H fins and the directional steering of airflow by the spiral fins result in less fouling and significantly lower flue resistance compared to conventional spiral fin designs. Thus, employing H-finned tubes can drastically minimize wind resistance, leading to reduced fan operation demands and lower associated costs.

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

Thanks to the patented zigzag design of the H fins, the fusion welding rate between the fins and steel pipes can impressively reach 98% or higher, ensuring an exceptional heat transfer coefficient.

(5) Compact Structure with Maximized Heat Efficiency

With a heating area per unit length that is a staggering 7.8 times greater than that of a smooth tube, the H-finned tube is an engineering marvel. The use of argon arc welding for butt joints significantly enhances welding quality compared to manual methods. The equipment's size and weight are notably reduced, drastically cutting down on investment costs for similar heat transfer areas while offering users more installation space.

(6) Vibration and Noise Reduction

Due to its innovative structural design and the unique characteristics of the H finned tube, the device functions as a muffler, adeptly reducing noise and absorbing vibrations.

(7) Easy Installation, Operation, and Maintenance

Installation is straightforward—simply connect the equipment to the exhaust gas outlet of HFO engine units, and it is ready for normal operation. The exhaust gas boiler is equipped with a check door, allowing you to determine the cleaning cycle based on actual conditions, thus ensuring optimal heat transfer and prolonging working life.
