Product Description

Description of H-fin Boiler Finned Tubes

Crafted with precision, the H-shaped fin tubes for boilers enhance the heat transfer process by welding two arcs of steel symmetrically onto the base tube, forming distinctive 'H' shaped fins. This innovative design revolutionizes efficiency in heat transfer. The rectangular, nearly square fins of the H-finned tube extend outwards, doubling the tube's diameter and significantly increasing the heat exchange surface area for optimal performance. Engineered for versatility, the H-finned tube can be configured into a 'double H' finned tube, featuring a robust double-tube structure. This design excels in providing rigidity and is ideal for longer tube rows.

H fin tubes are expertly utilized in recovering waste heat from power station boilers, industrial kilns, and marine power plants, among others. This application significantly boosts fuel efficiency by strategically positioning the heat exchange element at the tail end of the system flue.

 

Detail

 

Our H-type finned tube heat exchanger elements are engineered for high heat transfer capacity, offering excellent self-cleaning capabilities and effectively recovering waste heat in boiler renovations, all while maintaining superior performance. The convective heat transfer coefficient is intricately linked to the fin pitch; however, it decreases when fin height and width increase, emphasizing the importance of precise design. The overall heat transfer capacity is a complex interplay of fin efficiency, convective heat transfer coefficient, and the finned ratio, ensuring high performance in varied conditions. Although increasing the fin height and width can augment heat exchange, it also results in a higher pressure drop, necessitating a balance for optimal performance.

 

To maximize heat exchange efficiency and expand surface heat transfer, H-type finned tubes have become increasingly prevalent in modern boilers and waste heat recovery systems, demonstrating remarkable adaptability. Sharing their lineage with rectangular finned tubes, H-type finned tubes have evolved to meet modern demands for improved heat transfer and system efficiency. Thanks to the innovative groove structure on the fin surface, H-type finned tubes deliver outstanding anti-wear and anti-fouling performance, prolonging their lifespan and effectiveness.

 

Our H-fin tubes are customizable to meet specific client requirements, ensuring solutions that are both safe and effective. We prioritize reliability and efficiency in every product we design and manufacture.

 

The Economizer H Type Extruded Fin Tube is available in a range of materials, including copper and stainless steel, to meet diverse operational needs and environmental conditions. With a low fin design, these tubes offer compactness and are lightweight, making them perfect for installations where space is limited, without sacrificing performance.

 

Designed for versatility, this finned tube is ideal for use in air coolers, radiators, and a variety of heat exchanger applications, providing reliable and efficient heat transfer. Our meticulous manufacturing process ensures that each finned tube maintains precise dimensions and tight tolerances, allowing for seamless integration into existing systems and maximizing performance.

Product Details

Advantages of the H-finned Tube:

 

The H-finned tube is a critical component in exhaust gas boilers, boasting numerous advantages that elevate heat exchange efficiency and performance.

 

(1) Remarkable Wear Resistance

 

Designed with precision, the H-finned tube heat exchanger features a linear arrangement where the fins ingeniously divide the space into smaller sections. This design facilitates uniform air flow. Compared to conventional smooth tube exchangers with staggered designs, and even spiral finned exchangers, the H-finned tube significantly extends wear life by an impressive 3 to 4 times, standing the test of time.

 

(2) Minimized Fouling

 

Fouling typically forms on the dorsal and windward sides of tubes. Thanks to its staggered arrangement, the tube bundle is effortlessly cleansed, resulting in minimal fouling on the back side. At optimal wind speeds, its self-cleaning capability is enhanced, maintaining pristine conditions. Straight channels created by the fin structure allow efficient soot removal, optimizing performance with the use of soot blowers.

 

(3) Reduced Exhaust Gas Resistance

 

The H fins establish direct channels, guiding airflow seamlessly. In contrast, spiral fins redirect airflow, leading to increased fouling and higher resistance. Thus, the H-finned design minimizes flue resistance effectively. Consequently, employing H-finned tubes curtails wind resistance, thereby lowering both fan operation demands and associated investment costs.

 

(4) Superior Welding Fusion

 

With its proprietary zigzag design (patented), the welding fusion rate between fins and steel pipes achieves an outstanding 98% or more. This high fusion rate assures excellent heat transfer coefficients, optimizing thermal performance.

 

(5) Compact and Highly Efficient Structure

 

The H-finned tube offers substantial heating area per unit length, amounting to 7.8 times that of a smooth tube. Fully utilizing argon arc welding for butt joints, the quality of welds surpasses manual methods. This efficiency translates to reduced equipment size and weight, leading to significant investment savings, and grants users more installation flexibility. The resulting scale-down in equipment size enables a substantial reduction in investment while providing users with increased spatial freedom for equipment setup.

 

(6) Vibration and Noise Mitigation

 

Thanks to the thoughtful design and structural features of the H-finned tube, the equipment inherently possesses noise-cancelling properties, functioning effectively as a muffler.

 

(7) Easy Installation, Operation, and Maintenance

 

Installation is straightforward, involving only the connection of the equipment to the HFO engine unit's exhaust outlet for seamless operation. The exhaust gas boiler features an inspection door, allowing for the determination of cleaning intervals based on operational conditions, thereby ensuring optimal heat transfer and extending the equipment's operational lifespan.
