Product Description

Detailed Overview of H-Fin Boiler Finned Tubes

In the realm of advanced boiler technology, the heat transfer tube adopts the cutting-edge H-shaped fin tubes. These tubes are crafted by symmetrically welding two pieces of steel with arcs at their center onto the raw tube, creating distinctive fins (ribs). Its front view resembles the letter 'H', aptly earning the name H-finned tube. The H-finned tube boasts rectangular, almost square fins, doubling the tube's diameter in length. This design effectively extends the heating surface, enhancing heat transfer efficiency. Engineered for adaptability, the H-finned tube can be transformed into a 'double H' finned tube with dual tubes, providing a robust structure perfectly suited for extended rows of tubes.

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

In-Depth Product Details

H-type finned tube heat exchanger elements are renowned for their high heat transfer capacity, outstanding self-cleaning ability, and exceptional efficiency in recovering flue gas waste heat during boiler refurbishments. The convective heat transfer coefficient is directly related to fin pitch, yet it is inversely related to both fin height and width, optimizing thermal performance. Heat transfer capacity is intricately linked to fin efficiency, convective heat transfer coefficients, and the finned ratio, combining to deliver superior thermal conduction. As fin height and width increase, so does the pressure drop, a critical factor in optimizing tube performance.

To maximize heat exchange efficiency and surface heat transfer, H-type finned tubes have surged in popularity for boilers and waste heat recovery applications in recent years. H-type finned tubes are a sophisticated evolution of traditional rectangle finned tubes, offering enhanced performance. Thanks to their innovative groove structure on fin surfaces, H-type finned tubes deliver exceptional anti-wear and anti-fouling capabilities, ensuring long-lasting durability.

Our H-fin tubes are tailored to meet customer specifications and contextual needs. We design and manufacture safe, reliable, and efficient solutions, reflecting the pinnacle of engineering excellence.

Advantages of H-finned tube:

The H-finned tube stands as the core heat exchange component within the entire exhaust gas boiler system. It boasts several remarkable advantages, enhancing performance and efficiency.

(1) Outstanding Wear Resistance

In the H-finned tube heat exchanger, tubes are strategically aligned, with H fins segmenting the space into multiple small regions, effectively balancing airflow. Compared to smooth tube heat exchangers with staggered layouts and spiral finned exchangers, this design significantly boosts wear life, extending it by 3 to 4 times under similar conditions.

(2) Reduced Fouling

Fouling typically forms on the dorsal and windward sides of the tube. The staggered tube arrangement facilitates efficient flushing of the tube bundle, minimizing fouling at the back. The system exhibits a robust self-cleaning capability at optimal wind speeds. Straight channels formed on both sides of the H-finned tube efficiently manage soot, achieving optimal cleaning when paired with a soot blower.

(3) Lower Exhaust Gas Resistance

H fins create straight channels, guiding the airflow without obstruction. In contrast, spiral fin designs increase flue resistance and accumulate more fouling. The H-finned tube minimizes airflow resistance, reducing fan operation expenses and capital outlays. Thus, implementing H-finned tubes effectively lowers wind resistance, diminishing fan operational costs and capital investment.

(4) Exceptional Fin-to-Pipe Weld Fusion

With a unique, patented zigzag structure, the H fins achieve an impressive weld fusion rate of 98% or higher with steel pipes. This ensures excellent heat transfer efficiency in H-finned tubes.

(5) Compact Structure with High Heat Efficiency

The heating area per unit length in an H-finned tube is 7.8 times greater than that of a smooth tube. With butt welds executed via argon arc welding, the welding quality is significantly superior to manual methods. This results in a substantial reduction in equipment size and weight, thereby minimizing investment costs while providing users with more installation space.

(6) Shock-Proof with Noise Reduction

Thanks to its ingenious structural design, the H-finned tube functions as an effective muffler, significantly diminishing noise alongside its primary duties.

(7) Ease of Installation, Operation, and Maintenance

For installation, simply connect the equipment to the exhaust gas outlet of HFO engine units, enabling seamless operational integration. The exhaust gas boiler includes a check door, allowing for the determination of cleaning cycles based on actual conditions, ensuring optimal heat transfer and extended service life.
