Product Description

Description of H-fin boiler Finned Tubes

The heat transfer tube of the boiler adopts the H-shaped fin tubes, ingeniously crafted by symmetrically welding two steel pieces with arcs onto the raw tube to form the fins, resembling the letter 'H'. Thus, it is known as the H-finned tube, a marvel of innovation. These H-finned tube fins are designed in a rectangular, almost square shape, featuring a length that extends about twice the diameter of the tube, significantly enhancing the extended heating surface for optimal thermal performance. The H-finned tube can also be expertly fashioned into a 'double H' finned tube, featuring a robust double-tube structure. This design ensures excellent rigidity, making it ideal for application in longer rows of tubes, offering unmatched durability.

Deployed in recovering gas waste heat from power station boilers, industrial boilers, industrial kilns, ship power plants, and more, the H fin tube substantially boosts fuel efficiency. The heat exchange element is strategically positioned at the tail of the system flue to maximize its effectiveness.

Detail

H-type finned tube heat exchanger elements are engineered for high heat transfer capacity, boasting exceptional self-cleaning properties. These qualities make them perfect for effective flue gas waste heat recovery, especially during boiler renovations. The convective heat transfer coefficient is intricately tied to the fin pitch, and inversely related to fin height and width, ensuring optimized heat exchange performance. Integrated heat transfer capacity is influenced by factors such as fin efficiency, convective heat transfer coefficient, and finned ratio, making these parameters crucial for superior performance. Pressure drop sees an increase with the escalation of fin height and fin width, a consideration vital for system design.

To enhance heat exchange efficiency and extend surface heat transfer, H-type finned tubes have found widespread application in boilers and waste heat recovery systems, gaining popularity in recent years. H-type finned tubes largely evolve from their rectangle finned tube predecessors, a testament to their superior design and capability. Thanks to their distinctive groove structure on the fin surface, H-type finned tubes excel in anti-wear and anti-fouling performance, making them a reliable choice in demanding environments.

Our products are customizable to meet our customers' specific demands and conditions. We are dedicated to designing and manufacturing safe, reliable, and efficient H-fin tubes that exceed expectations.

The Economizer H Type Extruded Fin Tube is available in diverse materials such as copper and stainless steel, catering to a variety of unique requirements, ensuring versatility and reliability. Featuring a low fin design, this product ensures a compact and lightweight structure, perfectly suited for installations where space is at a premium.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the primary component for heat exchange within exhaust gas boilers. Its superiority is marked by the following advantages:

(1) Excellent Wear Resistance

Unlike conventional staggered or spiral finned tube heat exchangers, the H-finned tube heat exchanger is precisely aligned. This strategic arrangement divides the airflow into smaller, uniform segments, significantly enhancing wear resistance. In fact, under identical conditions, its longevity surpasses that of other designs by 3 to 4 times, ensuring durability and reliability.

(2) Reduced Fouling

Fouling is typically observed on both the dorsal and windward sides of the tube. The staggered arrangement contributes to easier cleaning of the tube bundle, with reduced fouling on the backside. Featuring an excellent self-cleaning capability at optimal wind speeds, the H-finned tube minimizes maintenance demands. The straight channels formed alongside the H fins improve soot expulsion when paired with a soot blower, achieving maximum soot removal efficiency.

(3) Minimized Exhaust Gas Resistance

Straight channels created by the H fins streamline airflow, unlike spiral fins which may increase fouling and flue resistance. This design advantage allows for decreased wind resistance and leads to lower fan operation and investment costs. Consequently, utilizing H-finned tubes translates into reduced wind resistance, cutting down operational costs and minimizing initial investment in fan systems.

(4) High Fusion Rate Between Fins and Steel Pipe

The unique zigzag design of the patented H fins results in a remarkable weld fusion rate of 98% or higher, ensuring an optimal heat transfer coefficient and enhancing overall efficiency.

(5) Compact Structure and High Heat Efficiency

The H finned tube boasts a heating area per unit length that is 7.8 times larger than that of a smooth tube. All butt welds are performed using superior argon arc welding, far surpassing the quality of manual welding, thereby maximizing heat efficiency. This compact design not only reduces the size and weight of the equipment but also slashes investment costs while offering expansive installation space for users.

(6) Shock-Proof and Noise Reduction

Thanks to the innovative structural design of the H finned tube, it doubles as a muffler. This feature diminishes noise, enhancing the operational environment.

(7) Easy Installation, Operation, and Maintenance

Installation is simplified by simply connecting the equipment to the exhaust gas outlet of HFO engine units, ensuring immediate operability. For maintenance, the exhaust gas boiler is equipped with a check door, allowing for the determination of cleaning cycles based on actual conditions, thereby optimizing heat transfer and prolonging the equipment's lifespan.
