Product Description

Description of H-fin Boiler Finned Tubes

The innovative heat transfer technology of our boiler features H-shaped fin tubes. By symmetrically welding two steel pieces with arcs onto the raw tube, a distinctive 'H' shaped fin is created, enhancing the efficiency and distribution of heat, earning it the name H-finned tube. The H-finned tube boasts rectangular fins that are nearly square, extending approximately twice the diameter of the tube to significantly increase the heating surface area and optimize heat transfer. Ingenious in its design, the H-finned tube can be transformed into a 'double H' version with a dual-tube structure, offering enhanced rigidity for longer tube arrangements in demanding applications.

The H fin tube is expertly crafted to reclaim waste heat from power station boilers, industrial boilers, kilns, and maritime power plants. This innovation boosts fuel utilization rates and strategically places the heat exchange element at the tail of the system flue for optimal efficiency.

Detail

Our H-type finned tube heat exchanger elements excel in maintaining superior heat transfer capacities, are self-cleaning, and are highly effective in recovering flue gas waste heat during boiler upgrades, ensuring outstanding performance. The convective heat transfer coefficient is intricately linked to fin pitch and inversely related to both fin height and width, offering a precise balance for optimal performance. The integrated heat transfer capacity is a result of the interplay between fin efficiency, convective heat transfer coefficient, and finned ratio, ensuring top-tier performance. As fin height and width increase, so does the pressure drop. This relationship is crucial for designing systems that balance performance with efficient pressure management.

In recent years, H-type finned tubes have become the top choice for enhancing heat exchange efficiency and extending surface heat transfer in boilers and waste heat recovery systems. The origins of H-type finned tubes can largely be traced back to rectangle finned tubes, from which they derive their exceptional efficiency and design innovations. Thanks to their specialized groove structure on the fin surface, H-type finned tubes deliver outstanding anti-wear and anti-fouling capabilities, setting a new standard in durability and performance.

Our customizable offerings allow us to adapt products to meet specific customer needs, ensuring that every H-fin tube we design and manufacture is safe, reliable, and extraordinarily efficient.

Our Economizer H Type Extruded Fin Tube is available in an array of materials, such as copper and stainless steel, meeting diverse requirements and ensuring reliable performance across various applications. The low fin design is a marvel of compactness and lightweight engineering, making it the perfect solution for installations where space is at a premium.

This versatile finned tube is ideally suited for applications such as air coolers, radiators, and a variety of heat exchangers, offering unmatched adaptability and efficiency. Our meticulous manufacturing process ensures precise dimensions and tight tolerances, guaranteeing that each component integrates seamlessly into your existing systems for flawless operation.

Product Details

Advantages of the H-Finned Tube:

The H-finned tube serves as the pivotal heat exchange component in the entire exhaust gas boiler system, boasting several remarkable advantages.

(1) Exceptional Wear Resistance

Unlike traditional smooth tube exchangers with staggered or spiral finned arrangements, the H finned tube exchanger is meticulously arranged in a linear sequence. The H fins ingeniously segment the space into multiple smaller zones, effectively equalizing the airflow. This arrangement dramatically enhances wear life, achieving a lifespan that is 3 to 4 times longer under similar conditions.

(2) Reduced Fouling

Fouling typically forms on the dorsal and windward sides of the tube, hindering efficiency. The staggered configuration of the tubes facilitates the easy flushing of the tube bundle, minimizing fouling on the posterior side. At optimal wind speeds, it exhibits impressive self-cleaning capabilities. Straight channels form on both sides of the H finned tube, enabling optimal soot clearance when employing soot blowers.

(3) Reduced Exhaust Gas Resistance

The straight channels formed by the H fins, combined with the strategic spiral angle of spiral fins, direct airflow efficiently. This design reduces the propensity for fouling and significantly lowers flue resistance compared to traditional fins. Adopting H-finned tubes markedly decreases wind resistance, leading to reduced fan operation and significant cost savings on investments.

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

Thanks to its distinctive zigzag structure (patented), the weld fusion rate between H fins and steel pipes exceeds a remarkable 98%, ensuring an outstanding heat transfer coefficient.

(5) Compact Structure, Superior Heat Efficiency

The H finned tube offers an expansive heating area per unit length, 7.8 times greater than that of smooth tubes. The usage of argon arc welding for butt welds elevates welding quality far beyond that of manual techniques. With substantial reductions in equipment size and weight, both investment costs and installation space requirements are significantly minimized, providing users with enhanced installation flexibility.

(6) Shock-Proof and Noise Reduction

The structural design of the H finned tube incorporates inherent muffler characteristics, enabling the equipment to effectively function as a noise suppressor.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward, requiring only the connection of the equipment to the exhaust gas outlet of HFO engine units to commence standard operation. The exhaust gas boiler includes an inspection door, facilitating the determination of cleaning cycles based on real-time conditions to maintain optimal heat transfer and extend equipment longevity.
