Product Description

Description of H-fin Boiler Finned Tubes

The cutting-edge heat transfer solution for boilers involves the ingenious use of H-shaped fin tubes. These are crafted by symmetrically welding two curved steel pieces onto the raw tube, forming characteristic 'H' shaped fins (ribs). This innovation not only enhances the heat transfer capabilities but also provides a unique structural profile, earning its name as the H-finned tube. The H-finned tube's fins boast a rectangular, nearly square design, ingeniously doubling the tube's diameter in length. This construction significantly extends the heating surface, optimizing thermal efficiency. For extended applications, the H-finned tube can be engineered into a 'Double H' configuration, utilizing a twin-tube design. This provides a robust and rigid structure, ideal for accommodating longer tube arrays, enhancing durability and performance.

The H fin tube is an essential component for recapturing gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants. By optimizing fuel utilization, these tubes effectively serve as heat exchange elements positioned strategically at the system's flue tail.

Detail

H-type finned tube heat exchanger elements stand out with their remarkable heat transfer capacity, outstanding self-cleaning properties, and unrivaled efficiency in recovering flue gas waste heat during boiler upgrades. The convective heat transfer coefficient is meticulously balanced; it increases with fin pitch while being inversely affected by fin height and width, ensuring optimal thermal dynamics. Overall heat transfer prowess hinges on fin efficiency, convective heat transfer coefficient, and the finned ratio, creating an integrated system of superior performance. Fin height and width directly impact pressure drop, with increases in these dimensions leading to higher pressure profiles, necessitating careful design consideration.

H-type finned tubes have gained widespread acclaim and adoption in recent years for their ability to enhance heat exchange efficiency and amplify surface heat transfer in boilers and waste heat recovery systems. The evolution of H-type finned tubes finds its roots in rectangle finned tubes, advancing in design and function to meet contemporary thermal demands. Thanks to the innovative groove structure on the fin surface, H-type finned tubes deliver superior anti-wear and anti-fouling performance, ensuring longevity and reliability.

Our product range is fully adaptable to meet the bespoke needs of our clients and situational demands. We are dedicated to designing and manufacturing H-fin tubes that promise safety, reliability, and efficiency.

Product Details

Advantages of H-finned tube:

The H-finned tube serves as the cornerstone of heat exchange within the exhaust gas boiler, boasting a plethora of unparalleled advantages.

(1) Outstanding Wear Resistance

This exceptional heat exchanger, featuring an in-line arrangement, ingeniously transforms space into numerous small areas using H fins. This design harmonizes air flow, delivering wear life that surpasses traditional smooth tube and spiral finned heat exchangers by 3 to 4 times under identical conditions.

(2) Minimized Fouling

Fouling typically occurs on both the dorsal and windward sides of the tube, posing a challenge. However, the staggered design facilitates effortless flushing of the tube bundle, significantly reducing fouling on the back side. Moreover, the tube's remarkable self-cleaning capability is activated at optimal wind speeds, ensuring peak performance. Straight channels formed on either side of the H finned tube enhance soot removal efficiency, especially when using a soot blower.

(3) Lower Exhaust Gas Resistance

The formation of straight channels by H fins, complemented by the spiral angle of spiral fins that guide airflow direction, reduces fouling and minimizes flue resistance compared to conventional designs. Hence, incorporating H-finned tubes significantly cuts down wind resistance, leading to reduced fan operation and investment expenses.

(4) Superior Fins and Steel Pipe Weld Fusion

With a unique patented zigzag structure, the weld fusion rate between H fins and steel pipes can achieve a remarkable 98% or higher, guaranteeing an exceptional heat transfer coefficient.

(5) Compact Design and High Heat Efficiency

Featuring a heating area per unit length that is 7.8 times greater than smooth tubes, and utilizing argon arc welding for superior weld quality, this design greatly enhances efficiency. The reduced size and weight lead to lower equipment investment and provide ample installation space. This optimization ensures not only cost savings but also offers larger installation space, enhancing user convenience and versatility.

(6) Enhanced Shock-Proof and Noise Reduction

Thanks to the innovative structural design and intrinsic muffler characteristics of the H finned tube, the equipment functions effectively as a noise-reducing muffler.

(7) Ease of Installation, Operation, and Maintenance

Installation is a breeze—simply connect the equipment to the exhaust gas outlet of HFO engine units, and it's ready for normal operation. With an exhaust gas boiler featuring a check door, maintenance cycles can be adjusted based on real-time conditions to ensure optimal heat transfer and prolong equipment lifespan.
