Product Description

Experience the cutting-edge innovation in boiler technology with our H-fin boiler Finned Tubes, a pinnacle of efficiency and durability.

At the heart of our innovation, the heat transfer tube of the boiler features H-shaped fin tubes. Ingeniously engineered, these tubes are crafted by symmetrically welding two steel pieces with arcs to the raw tube, forming prominent fins that resemble the letter 'H'. Hence, they are aptly named H-finned tubes. The fins on these state-of-the-art H-finned tubes are meticulously designed to be rectangular and nearly square, extending approximately twice the tube's diameter. This design significantly enhances the heating surface, optimizing heat transfer. Elevating versatility, the H-finned tube can also be transformed into a 'double H' finned tube. This dual-tube configuration offers exceptional structural rigidity, making it ideal for longer tube arrays.

Our H fin tubes are expertly engineered to reclaim gas waste heat from various sources including power station boilers, industrial boilers, kilns, and marine power plants. They effectively enhance fuel utilization rates, strategically positioned at the system flue's tail as vital heat exchange elements.

Detail

Our H-type finned tube heat exchanger elements are renowned for their exceptional heat transfer capacity. They boast superior self-cleaning abilities and are pivotal in recovering flue gas waste heat during boiler renovations. The convective heat transfer coefficient is intricately linked to the fin pitch, while it inversely relates to both fin height and fin width, optimizing thermal efficiency. Integrated heat transfer capacity is a harmonious blend of fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring unmatched performance. Be aware that pressure drop escalates with increased fin height and width — a critical consideration in system design.

To elevate heat exchange efficiency and extend surface heat transfer, H-type finned tubes have become a staple in modern boilers and waste heat recovery systems. Rooted in innovation, H-type finned tubes evolve primarily from the sophisticated design of rectangle finned tubes. Thanks to their unique groove structure on the fin surface, H-type finned tubes deliver remarkable anti-wear and anti-fouling performance for long-lasting reliability.

Catering to diverse requirements, our products are customizable based on customer needs and specific circumstances. We are dedicated to designing and manufacturing H-fin tubes that are synonymous with safety, reliability, and efficiency.

Our Economizer H Type Extruded Fin Tube is available in a variety of materials such as copper and stainless steel, meeting an array of industry necessities. The low fin design ensures our tubes are both compact and lightweight, ideal for installations where space is at a premium.

This advanced finned tube is engineered for excellence in air coolers, radiators, and various other heat exchanger applications. Our precise manufacturing process guarantees impeccable dimensions and tight tolerances, ensuring seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the premier heat exchange component within exhaust gas boilers, boasting several compelling advantages that elevate its performance and efficiency.

(1) Exceptional Wear Resistance

Engineered for resilience, the H finned tube heat exchanger is strategically aligned in rows, with H fins that compartmentalize space into smaller sections. This design enhances air flow uniformity, setting it apart from conventional smooth tube heat exchangers arranged in a staggered formation or units with spiral fins. Under equivalent conditions, the durability of the H fins outlasts traditional models by a factor of 3 to 4.

(2) Minimized Fouling

Fouling typically manifests on both the dorsal and windward sides of the tube, yet this design offers a solution. With a staggered tube arrangement, the bundle is easily flushed, leading to significantly less fouling on the back side. This system incorporates an effective self-cleaning mechanism when operated at optimal wind speeds. Straight channels formed by the H fins efficiently manage soot accumulation, especially when complemented by a soot blower, achieving superior cleaning efficacy.

(3) Lowered Exhaust Gas Resistance

The configuration of H fins creates linear channels, while the spiral fins redirect airflow. Unlike their spiral counterparts, H fins exhibit reduced fouling and subsequently lower flue resistance. Thus, integrating H-finned tubes not only diminishes wind resistance but also curtails fan operational and capital expenses.

(4) Superior Fins and Steel Pipe Weld Fusion

Thanks to the innovative zigzag pattern (patented) of H fins, the weld fusion rate between fins and steel pipes impressively reaches 98% or higher, ensuring optimal heat transfer efficiency.

(5) Compact Structure with Elevated Heat Efficiency

The expansive heating surface per unit length of the H finned tube is 7.8 times greater than that of a smooth tube. Employing argon arc welding for butt joints enhances welding quality significantly beyond manual methods. With a substantial reduction in equipment size and weight, the investment in heat transfer equipment decreases markedly, offering users more installation space and flexibility.

(6) Shock Absorption and Noise Reduction

Innovatively designed, the structural design of the device, combined with the unique characteristics of the H finned tube, incorporates muffler features, allowing the equipment to double as a noise dampener.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward, requiring a simple connection to the exhaust gas outlet of HFO engine units, after which the equipment is ready for operation. The exhaust gas boiler is equipped with inspection doors, allowing cleaning cycles to be adjusted based on real-time conditions. This ensures consistent heat transfer and prolongs operational lifespan.
