Product Description

Description of H-fin boiler Finned Tubes

Dive into the world of advanced boiler technology with our innovative H-shaped fin tubes. These exceptional heat transfer tubes are meticulously crafted by symmetrically welding two arc-shaped steel pieces onto the raw tube, forming distinctive fins (ribs) reminiscent of the letter 'H'. This ingenious design not only optimizes thermal efficiency but also embodies the iconic appearance of the H-finned tube. Our H-finned tubes feature fins that are elegantly rectangular and nearly square, boasting a length approximately twice the diameter of the tube. This design significantly enlarges the heating surface, enhancing the tube's heat transfer capabilities. For added versatility and robustness, our H-finned tubes can be transformed into 'double H' finned tubes. This double-tube configuration not only strengthens the structure but also makes it suitable for applications requiring extended rows of tubes.

H fin tubes are quintessential in capturing and recycling the waste heat from various sources such as power station boilers, industrial boilers, kilns, and ship power plants. By doing so, they significantly boost fuel efficiency. The heat exchange elements are strategically positioned at the tail of the system flue to maximize energy recovery.

Detail

H-type finned tube heat exchanger elements are engineered to deliver exceptional heat transfer capabilities. Their superior self-cleaning properties and proficiency in flue gas waste heat recovery make them indispensable in boiler upgrades. The convective heat transfer coefficient in these tubes adjusts with fin pitch while being inversely related to fin height and width, allowing for tailored thermal management solutions. The overall heat transfer capacity is intricately tied to factors such as fin efficiency, convective heat transfer coefficient, and the finned ratio, ensuring optimal performance across applications. Note that pressure drop tends to increase as fin height and width increase, a critical consideration in system design.

To elevate heat exchange efficiency and expand surface heat transfer, H-type finned tubes have become increasingly popular in modern boilers and waste heat recovery systems. H-type finned tubes primarily evolve from rectangular finned tubes, offering distinct advantages in specific applications. Thanks to their innovative groove structure on the fin surface, H-type finned tubes excel in anti-wear and anti-fouling performance, making them ideal for demanding environments.

We pride ourselves on customizing our products to meet specific customer needs and situational demands. Our expertly designed and manufactured H-fin tubes are synonymous with safety, reliability, and efficiency.

Our Economizer H Type Extruded Fin Tube comes in a variety of materials, including copper and stainless steel, to accommodate diverse application requirements. The ingenious low fin design promotes compactness and light weight, perfectly suited for installations where space is at a premium.

This versatile finned tube is perfectly compatible with air coolers, radiators, and an array of heat exchanger applications, ensuring maximum adaptability. Our state-of-the-art manufacturing process guarantees precise dimensions and stringent tolerances, facilitating the seamless integration of our finned tubes into existing systems with ease.

Product Details

Advantages of H-finned Tube:

The H-finned tube stands as the principal heat exchange element of the exhaust gas boiler, offering a suite of unparalleled advantages.

(1) Outstanding Wear Resistance

In a meticulously aligned arrangement, the H-finned tube heat exchanger divides its space into multiple small compartments, optimizing airflow distribution. Unlike staggered or spiral finned heat exchangers, under identical conditions, the wear life of H-finned tubes is notably extended by 3 to 4 times.

(2) Reduced Fouling

Fouling typically forms on the dorsal and windward sides of the tube. The strategic staggered arrangement facilitates easy cleaning of the tube bundle, thereby reducing fouling on the backside. It boasts a self-cleaning capability when operating at optimal wind speeds. With straight channels formed on either side of the H-finned tube, it achieves superior soot removal with the use of a soot blower, maximizing efficiency.

(3) Minimized Exhaust Gas Resistance

Thanks to the linear channels created by the H fins and the direction-steering spiral angles, these fins experience less fouling and offer lower flue resistance compared to conventional designs. Thus, H-finned tubes effectively decrease wind resistance, leading to reduced fan operation and lower investment costs.

(4) High Welding Fusion Rate between Fins and Steel Pipe

Owing to the patented zigzag structure of the H fins, the weld fusion rate between fins and steel pipes exceeds 98%, ensuring optimal heat transfer coefficients.

(5) Compact Structure, Superior Heat Efficiency

The expansive heating area per unit length of the H-finned tube is 7.8 times that of a smooth tube, with argon arc welding enhancing the quality far beyond manual welding techniques. This leads to significantly reduced equipment size and weight, allowing substantial investment savings and more installation space.

(6) Vibration Dampening and Noise Reduction

Thanks to the intricate design and inherent structural features of the H-finned tube, the equipment also serves as an effective muffler.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward, requiring only a connection to the exhaust gas outlet of HFO engine units for standard operation. With an accessible check door, the cleaning cycle can be adjusted based on actual conditions to maintain heat transfer efficiency and prolong service life.
