Product Description

Description of H-fin Boiler Finned Tubes

The heat transfer tube of the boiler ingeniously incorporates the H-shaped fin tubes. This design involves welding two precisely crafted steel pieces, each with an arc, symmetrically onto the raw tube, creating fins (or ribs) that resemble the letter 'H'. This distinctive shape is why it is called the H-finned tube. The fins of the H-finned tube are meticulously rectangular, almost square, and extend to about twice the tube's diameter, offering an enhanced heating surface for optimal performance. Ingeniously, the H-finned tube can be adapted into a 'double H' finned tube for double-tube configurations. This setup provides remarkable structural rigidity, making it suitable for longer rows of tubes.

The H fin tube is a versatile solution used to reclaim gas waste heat from power station boilers, industrial boilers, kilns, and ship power plants. This innovation significantly boosts fuel utilization rates, with the heat exchange element strategically positioned at the system flue's tail end.

Detail

H-type finned tube heat exchanger elements are masterfully engineered to maintain superior heat transfer capabilities. They boast exceptional self-cleaning properties, efficiently recovering flue gas waste heat, ideal for boiler renovations. The convective heat transfer coefficient is directly related to the fin pitch yet inversely related to both the fin height and width, indicating a sophisticated balance in design. The overall heat transfer capacity is intricately linked to fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring a holistic approach to thermal management. As the fin height and width increase, there is a corresponding rise in the pressure drop, showcasing the intricacy of balancing design parameters.

To elevate heat exchange efficiency and expand surface heat transfer, H-type finned tubes have seen widespread adoption in boilers and waste heat recovery systems in recent years, marking a significant advancement in thermal technology. The evolution of H-type finned tubes largely draws inspiration from rectangular finned tubes, highlighting a process of refined innovation. Thanks to their distinctive groove structure on the fin surface, H-type finned tubes offer outstanding anti-wear and anti-fouling performance, ensuring longevity and reliability.

Our products are meticulously customizable to meet customer-specific requirements and situational demands. We take pride in designing and manufacturing H-fin tubes that stand for safety, reliability, and efficiency.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the pioneering heat exchange component within the entire exhaust gas boiler system. It boasts an array of exceptional benefits that set it apart.

(1) Excellent wear resistance

In a meticulously aligned arrangement, the H finned tube heat exchanger uses its innovative H fins to partition the space into multiple smaller segments. This design ensures uniform air distribution, offering a significant advantage over conventional smooth tube heat exchangers with staggered configurations and even spiral finned counterparts. Under equivalent conditions, its wear lifespan is remarkably 3 to 4 times longer.

(2) Reduced fouling

Fouling typically arises on both the dorsal and windward sides of the tube. Thanks to its staggered tube configuration, the design facilitates efficient flushing of the tube bundle, thereby minimizing fouling on the rear side. At optimal wind speeds, it showcases excellent self-cleaning capabilities. The H finned tube forms direct channels on either side, optimizing soot removal. Coupled with a soot blower, it achieves unparalleled soot cleaning efficacy.

(3) Reduced resistance of exhaust gas

H fins craft straight channels, while the spiraled angles of traditional spiral fins redirect airflow, often leading to fouling and increased flue resistance. H fins triumph by significantly reducing these issues. As a result, the utilization of H-finned tubes dramatically lowers wind resistance, effectively cutting down on fan operation costs and initial investments.

(4) High fusion rate of fins and steel pipe welding

Thanks to the ingenious patented zigzag design of the H fins, the weld fusion rate between fins and steel pipes skyrockets to 98% or higher, ensuring an outstanding heat transfer coefficient.

(5) Compact structure, high heat efficiency

Featuring an expansive heating area per unit length, the H finned tube's efficiency is an astonishing 7.8 times greater than that of a smooth tube. Employing argon arc welding for butt welds elevates welding quality far beyond manual methods. With equipment size and weight significantly reduced, investment costs for the same heat transfer surface are minimized. This means user installations can benefit from enhanced space availability.

(6) Shock-proof and noise reduction

Thanks to the strategic structural design of the H finned tube, it incorporates characteristics akin to a muffler, enabling the equipment to serve as an effective noise damping solution.

(7) Convenient for installation, operation and maintenance

Installation is a breeze, requiring only the connection of the equipment to the exhaust gas outlet of HFO engine units, allowing for seamless and immediate operation. The exhaust gas boiler is equipped with a check door, facilitating tailored cleaning cycles based on real-time conditions, thereby maintaining optimal heat transfer and extending operational longevity.
