Product Description

Description of H-fin Boiler Finned Tubes

The innovative heat transfer tube of the boiler features H-shaped fin tubes. It achieves its form by symmetrically welding two steel pieces, with arcs in the middle, onto the base tube, creating distinct fins (ribs). The frontal appearance resembles the letter 'H,' thus earning the name H-finned tube. The H-finned tube boasts rectangular fins that are nearly square, extending approximately twice the diameter of the tube. This results in an expanded heating surface for optimized performance. The H-finned tube can also be crafted into a 'double H' finned tube using double tubes. Its robust structure makes it ideal for applications requiring longer rows of tubes.

H-fin tubes are essential for recovering waste heat from gas in power station boilers, industrial boilers, kilns, and ship power plants. They significantly enhance fuel utilization and are strategically placed at the tail end of system flues to optimize heat exchange.

Detail

H-type finned tube heat exchanger components offer exceptional heat transfer capabilities and superior self-cleaning properties. They are crucial for flue gas waste heat recovery, especially in boiler renovations. The convective heat transfer coefficient is directly proportional to the fin pitch, while inversely related to the fin height and width, highlighting the importance of precise design. The comprehensive heat transfer capacity is influenced by fin efficiency, the convective heat transfer coefficient, and the finned ratio, showcasing the integrated approach to thermal management. As fin height and width increase, so does the pressure drop, which must be managed to maintain efficient operation.

To boost heat exchange efficiency and extend surface heat transfer, H-type finned tubes are increasingly employed in boilers and waste heat recovery systems. H-type finned tubes primarily evolve from rectangular finned tubes, offering a familiar yet enhanced design for various applications. Thanks to their unique grooved fin surface, H-type finned tubes exhibit excellent anti-wear and anti-fouling characteristics, ensuring durability and longevity.

Our products are highly customizable to meet customer needs and specific conditions. We design and manufacture 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 cater to a wide array of requirements. With its low fin design, this tube is compact and lightweight, making it perfect for installations where space is at a premium.

This versatile finned tube is ideal for air coolers, radiators, and a variety of heat exchanger applications, showcasing its adaptability. Produced with precision, its manufacturing process ensures exact dimensions and tight tolerances, allowing for seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the pivotal heat exchange component within the entire exhaust gas boiler system. It boasts several remarkable advantages that enhance its performance and longevity.

(1) Excellent wear resistance

Within the H-finned tube heat exchanger, tubes are meticulously arranged in a linear formation. The strategically placed H fins compartmentalize the space into multiple smaller areas, effectively balancing the airflow. Compared to staggered arrangements and spiral finned heat exchangers, this design significantly extends wear life by 3 to 4 times.

(2) Fouling reduced

Fouling typically forms on both the dorsal and windward sides of the tube. The staggered tube arrangement facilitates easy flushing of the tube bundle, resulting in reduced fouling on the backside. At optimal wind speeds, it exhibits impressive self-cleaning capabilities. With straight channels formed on both sides of the H-finned tube, soot removal is optimized with the use of a soot blower, ensuring superior cleaning efficacy.

(3) Reduce the resistance of exhaust gas

The H fins create straight channels on both sides, minimizing flue resistance more effectively than spiral fins. The spiral angle of the spiral fins redirects airflow, which can lead to greater fouling and resistance. H fins diminish this resistance, allowing for smoother airflow. Incorporating H-finned tubes reduces wind resistance, subsequently lowering fan operational and investment costs.

(4) Fins and steel pipe welding fusion rate is high

Thanks to the proprietary zigzag design of the H fins, the weld fusion rate between fins and steel pipes can soar to 98% or beyond, ensuring optimal heat transfer efficiency in H-finned tubes.

(5) Compact structure, high heat efficiency

The H-finned tube offers an expansive heating area per unit length, a staggering 7.8 times greater than that of a smooth tube. Employing argon arc welding for butt welds significantly enhances weld quality beyond manual welding capabilities. The equipment's size and weight see substantial reductions, leading to decreased investment costs for the same heat transfer surface area, while offering users more installation space.

(6) Shock-proof and noise reduced

Boasting a design that incorporates noise-dampening features, the H-finned tube's structural characteristics enable it to function effectively as a muffler.

(7) Convenient for installation, operation and maintenance

Installation is straightforward, requiring only a connection to the exhaust gas outlet of HFO engine units for normal operation. Equipped with an inspection door, the exhaust gas boiler allows for customized cleaning cycles based on real-time conditions, ensuring optimal heat transfer and extended service life.
