Product Description

Description of H-fin boiler Finned Tubes

The innovative heat transfer system of our boilers proudly embraces the H-shaped fin tubes. These tubes are designed with a unique welding technique: two meticulously crafted steel sheets, bent in the middle, are symmetrically welded onto the raw tube, creating the iconic 'H' fins. This engineering marvel not only resembles the letter 'H' but also epitomizes efficiency and performance, hence the name H-finned tube. H-finned tubes feature elegantly rectangular, nearly square fins that extend the heating surface dramatically, with a length that is approximately double the tube's diameter. This clever design maximizes heat exchange capability, making it a superior choice for industrial applications. Our H-finned tubes can be further enhanced by transforming into 'double H' configurations. This involves a strategic design using double-tubes, resulting in a structure with remarkable rigidity, perfectly suited for extended rows of tubes and high-demand environments.

H-fin tubes excel in capturing and utilizing residual heat from power station boilers, industrial boilers, kilns, maritime power plants, and more. Their strategic placement at the system flue's tail significantly boosts fuel efficiency, making them indispensable for heat exchange applications.

Detail

These H-type finned tube heat exchanger elements demonstrate exceptional heat transfer capabilities. With superior self-cleaning properties, they are adept at recovering flue gas waste heat during boiler renovations, thus proving their versatility and efficiency. The convective heat transfer coefficient is intricately linked to the fin pitch, yet inversely related to both the fin height and width. This relationship guides the design for optimal performance. The overall heat transfer capacity is a function of fin efficiency, the convective heat transfer coefficient, and the finned ratio, highlighting the intricate synergy of these elements in heat exchange processes. An increase in fin height and width correlates to a higher pressure drop, a factor crucial in the engineering considerations for system optimization.

In a bid to enhance heat exchange efficiency and expand the surface area for heat transfer, H-type finned tubes have seen widespread adoption in boilers and waste heat recovery systems, becoming a cornerstone of modern thermal management. The genesis of H-type finned tubes can be traced back to their rectangular finned tube ancestors, evolving significantly to meet contemporary heat exchange demands. Due to their specialized grooved surface, H-type finned tubes boast outstanding anti-wear and anti-fouling properties, ensuring longevity and sustained performance.

Our H-fin tubes are engineered with precision to meet customer-specific requirements. We pride ourselves on designing and manufacturing products that are synonymous with safety, reliability, and unparalleled efficiency.

The Economizer H Type Extruded Fin Tube is crafted from top-tier materials such as copper and stainless steel, catering to a diverse range of specifications and operational needs. The ingenious low fin design ensures these tubes remain compact and lightweight, perfect for installations where space is at a premium, without compromising on performance.

These finned tubes are versatile, finding applications in air coolers, radiators, and various heat exchangers, proving their adaptability across different thermal systems. Our advanced manufacturing techniques ensure that each finned tube meets precise dimensional standards and stringent tolerances, facilitating seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube serves as the primary heat exchange component within the exhaust gas boiler. This remarkable H finned tube boasts several distinct advantages.

(1) Excellent wear resistance

The H finned tube heat exchanger is elegantly arranged in a linear formation. The H fins ingeniously segment the space into multiple small areas, effectively equalizing the airflow. When compared to the conventional smooth tube heat exchanger with its staggered layout and the spiral finned heat exchanger, the H finned tube exhibits a wear life that is impressively 3 to 4 times longer under identical conditions.

(2) Fouling reduced

The formation of fouling occurs on the dorsal and windward sides of the tube. Thanks to its staggered arrangement, the tube bundle is easily flushed, resulting in significantly reduced fouling on the backside. With optimal wind speed, the H-finned tube demonstrates an excellent self-cleaning capability. On each side of the H finned tube, straight channels allow for effective soot management, achieving optimal soot removal when utilizing a soot blower.

(3) Reduce the resistance of exhaust gas

H fins form linear channels on both sides, while the spiral angle of spiral fins guides airflow direction. This design minimizes fouling and reduces flue resistance, offering an advantage over traditional designs. Consequently, the use of H-finned tubes significantly lowers wind resistance, reducing both fan operation costs and initial investment expenses.

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

Featuring a patented unique zigzag structure, H fins achieve a remarkable weld fusion rate with steel pipes of 98% or more, ensuring a superior heat transfer coefficient.

(5) Compact structure, high heat efficiency

The heating area per unit length is substantial; the H finned tube offers a heating capacity 7.8 times greater than that of a smooth tube. All butt welds are executed using argon arc welding, significantly enhancing welding quality compared to manual methods. With a reduced size and weight of the equipment, investment in equipment is minimized, providing users with more space for equipment installation, all while maintaining the same heat transfer surface.

(6) Shock-proof and noise reduced

Thanks to the structural design of the device and the distinct characteristics of the H finned tube, this equipment inherently functions as a muffler, reducing noise and vibration.

(7) Convenient for installation, operation and maintenance

Installation is straightforward; simply connect the equipment to the exhaust gas outlet of HFO engine units, and it's ready for normal operation. The exhaust gas boiler features a check door, allowing the cleaning cycle to be determined based on actual conditions. This ensures optimal heat transfer and extends the working life of the equipment.
