Product Description

Description of H-Fin Boiler Finned Tubes

Our innovative H-shaped finned tubes for boilers feature a unique design where two steel strips are welded onto the raw tube, forming a structure reminiscent of the letter 'H.' This sophisticated construction enhances heat transfer efficiency exponentially. The H-finned tube's rectangular fins, nearly square in shape, extend approximately twice the tube's diameter. This design significantly increases the heating surface area, optimizing thermal performance. For applications demanding robustness, the H-finned tube can be crafted into a 'double H' configuration, featuring a dual-tube structure that offers exceptional rigidity, ideal for longer tube rows.

H fin tubes excel in recovering waste heat from power station boilers, industrial boilers, kilns, and marine power plants. They significantly boost fuel efficiency, with the heat exchange elements strategically placed at the system's flue tail.

Detail

These H-type finned tube heat exchanger elements boast a formidable heat transfer capacity, excellent self-cleaning properties, and are highly effective in flue gas waste heat recovery, especially during boiler upgrades. The efficiency of convective heat transfer is directly proportional to the fin pitch yet inversely proportional to both the fin height and width, optimizing thermal dynamics. The overarching heat transfer ability hinges on fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring a seamless thermal exchange process. Increases in fin height and width directly correlate to a rise in pressure drop, necessitating precise engineering control.

To enhance heat exchange efficiency and expand the surface heat transfer area, H-type finned tubes have become indispensable in modern boilers and waste heat recovery systems. H-type finned tubes primarily evolve from rectangular finned tube designs, integrating advanced engineering insights. Thanks to their distinctive grooved fin surface, H-type finned tubes deliver remarkable anti-wear and anti-fouling performance, ensuring longevity and reliability.

Tailored to meet customer specifications and unique conditions, our H-fin tubes are engineered for safety, reliability, and efficiency, setting industry standards.

The versatile Economizer H Type Extruded Fin Tube is offered in diverse materials like copper and stainless steel, addressing varied industrial needs seamlessly. Our fin tube's low fin design ensures a compact and lightweight profile, perfect for installations where space constraints are critical.

Designed for versatility, these finned tubes are perfect for air coolers, radiators, and numerous heat exchanger applications. With a manufacturing process that ensures precise dimensions and tight tolerances, our finned tubes integrate seamlessly into existing systems.

Product Details

Advantages of H-finned tube:

At the heart of the exhaust gas boiler lies the H-finned tube, a superior heat exchange component. This ingeniously crafted tube offers the following remarkable advantages:

(1) Excellent wear resistance

The H-finned tube heat exchanger boasts an in-line arrangement of H fins, dividing space into multiple small zones that balance airflow. Compared to smooth tube or spiral finned heat exchangers, the H-finned tube outperforms with a 3-4 times longer wear life under identical conditions.

(2) Fouling reduced

Fouling typically forms on the dorsal and windward sides of the tube. Thanks to the staggered tube arrangement, the bundle is easily flushed, minimizing fouling on the backside. At optimal wind speeds, it exhibits excellent self-cleaning capabilities. Straight channels crafted on the H finned tube sides effectively manage soot, achieving optimal soot removal with a soot blower.

(3) Reduce the resistance of exhaust gas

The straight channels formed by H fins and the spiral angle of spiral fins direct airflow efficiently, reducing fouling and flue resistance in H fins compared to their counterparts. As a result, employing H-finned tubes reduces wind resistance, cutting fan operation and investment costs.

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

The H fins’ unique, patented zigzag design ensures an impressive weld fusion rate with the steel pipes, exceeding 98%, thereby guaranteeing outstanding heat transfer efficiency.

(5) Compact structure, high heat efficiency

The substantial heating area of the H finned tube, 7.8 times greater than that of smooth tubes, is achieved through precise argon arc welds, surpassing manual welding quality extensively. This results in significantly reduced equipment size and weight, leading to lower investment in the same heat transfer surface and offering users greater installation space.

(6) Shock-proof and noise reduced

Thanks to its structural design and the inherent characteristics of the H finned tube, the device also serves as a muffler, providing shock absorption and noise reduction.

(7) Convenient for installation, operation and maintenance

Installation is a breeze, requiring only connection to the exhaust gas outlet of HFO engine units for immediate operational readiness. The exhaust gas boiler features a check door, allowing determination of the cleaning cycle based on real conditions to maintain heat transfer efficiency and prolong working life.
