Product Description

Description of H-fin Boiler Finned Tubes

The advanced heat transfer tube of our cutting-edge boilers incorporates the ingenious H-shaped fin tubes. This design elegantly welds two symmetrically placed steel pieces with graceful arcs onto the central raw tube, forming distinctive fins akin to the letter 'H.' This configuration is aptly named the H-finned tube and is engineered to boost heat efficiency like never before. The H-finned tube's fins are meticulously crafted to be rectangular and nearly square, extending approximately twice the tube's diameter. This design significantly expands the heating surface, ensuring unparalleled heat distribution and efficiency. For those requiring superior rigidity, the H-finned tube can be further enhanced into a 'double H' finned tube, utilizing a robust double-tube structure. This modification is ideal for accommodating longer tube rows, providing unmatched durability and performance.

The H-fin tube shines in applications such as recovering gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants. By optimizing fuel utilization and arranging the heat exchange elements at the system's flue tail, it elevates energy efficiency to new heights.

Detail

Featuring high heat transfer capacity, the H-type finned tube heat exchangers champion superior self-cleaning properties. Their unique ability to recover flue gas waste heat makes them indispensable in modern boiler renovations. The convective heat transfer coefficient is influenced by fin pitch, inversely affected by fin height and width, thus allowing precise control over heat transfer dynamics. The integrated heat transfer capacity is a holistic measure, intricately linked to factors like fin efficiency, convective heat coefficient, and the finned ratio, ensuring top-tier performance. As fin height and width increase, so does the pressure drop, necessitating careful balancing for optimal performance.

In an endeavor to enhance heat exchange efficiency and surface heat transfer, H-type finned tubes have become a cornerstone in recent boiler applications and waste heat recovery systems. H-type finned tubes are predominantly derived from their rectangular counterparts, offering a fresh perspective on classic finned tube applications. Thanks to their uniquely grooved fin surface, H-type finned tubes deliver exceptional anti-wear and anti-fouling performance, setting the standard for longevity and reliability.

Our versatile products can be customized to meet specific customer needs. We pride ourselves on designing and manufacturing H-fin tubes that are not only safe but also reliable and highly efficient.

The Economizer H Type Extruded Fin Tube is crafted from a range of materials including copper and stainless steel, catering to diverse application requirements. With a low fin design that ensures both compactness and lightweight, these tubes are ideally suited for installations where space is at a premium.

This exceptionally designed finned tube is perfect for air coolers, radiators, and a myriad of other heat exchanger applications, ensuring versatility and adaptability. Our state-of-the-art manufacturing process guarantees precision dimensions and tight tolerances, allowing for effortless integration into existing systems with zero hassle.

Product Details

Advantages of H-finned tube:

The H-finned tube is an essential heat exchange element within the entire exhaust gas boiler. Its innovative design and engineering provide several distinctive advantages.

(1) Superior Wear Resistance

With an inline configuration, the H fins segment the space into smaller areas, equalizing airflow. Compared to smooth tube heat exchangers with a staggered layout, and spiral finned heat exchangers, the H finned tube boasts a wear life that is 3 to 4 times longer under identical conditions.

(2) Reduced Fouling Potential

Fouling typically forms on both the dorsal and windward side of tubes. The staggered tube arrangement facilitates easier cleaning of the tube bundle, leading to significantly reduced fouling on the backside. It offers an excellent self-cleaning capability when operated at optimal wind speeds. Straight channels formed on the sides of the H finned tube effectively channel soot, achieving optimal soot removal when combined with a soot blower.

(3) Minimized Exhaust Gas Resistance

With straight channels created by H fins and controlled airflow via spiral angels, the H fins significantly reduce the propensity for fouling and lower flue resistance compared to spiral fins. This design reduces wind resistance, decreases fan operation demands, and lowers investment costs for the system.

(4) High Welding Fusion Rate

Featuring a patented zigzag structure, the H fins achieve a weld fusion rate with steel pipes of 98% or more, ensuring excellent heat transfer efficiency.

(5) Efficient, Compact Structure

Boasting a heating area per unit length 7.8 times greater than smooth tubes, H finned tubes utilize argon arc welding for butt welds, enhancing welding quality beyond traditional manual techniques. This results in significantly reduced equipment size and weight, lowering investment costs while providing more installation space for users.

(6) Vibration and Noise Reduction

Innovative structural design and the unique properties of the H finned tube confer noise cancellation features, allowing the system to serve as a muffler.

(7) Easy Installation, Operation, and Maintenance

Connecting the equipment to the exhaust gas outlet of HFO engine units allows for seamless transition to normal operation. A check door on the exhaust gas boiler enables determination of cleaning cycles based on actual conditions, optimizing heat transfer and extending operational lifespan.
