Product Description

Description of H-fin boiler Finned Tubes

The heat transfer tube of the boiler features innovative H-shaped fin tubes. Through a meticulous welding process, two steel pieces, each with a central arc, are symmetrically affixed to the raw tube, resulting in fins that resemble the letter 'H.' Hence, they are aptly named H-finned tubes. The fins on the H-finned tubes boast a distinctive rectangular shape, nearly square, with a length twice that of the tube's diameter, thereby creating an expansive extended heating surface. For greater structural integrity and enhanced performance, the H-finned tube can be transformed into a 'double H' finned tube, accommodating double-tube configurations ideal for longer tube arrays.

The H fin tube is adept at recovering gas waste heat in power station boilers, industrial boilers, kilns, and marine power plants. This capability significantly boosts fuel efficiency, while strategically placing the heat exchange element at the system flue tail for optimal performance.

Detail

H-type finned tube heat exchanger elements are engineered for high heat transfer capacity, superior self-cleaning, and proficient flue gas waste heat recovery, making them indispensable in boiler upgrade projects. Convective heat transfer coefficient has a direct correlation with fin pitch but is inversely related to both fin height and width, impacting overall efficiency. The total heat transfer capability is intricately linked to fin efficiency, convective heat transfer coefficient, and the finned ratio, all essential for optimal performance. As fin height and width increase, so does the pressure drop, necessitating careful design to balance performance and efficiency.

To elevate heat exchange efficiency and enhance surface heat transfer, H-type finned tubes have become increasingly prevalent in boilers and waste heat recovery endeavors. H-type finned tubes are primarily evolved from the traditional rectangle finned tubes to offer better performance and durability. With a unique grooved structure on the fin surface, H-type finned tubes exhibit excellent anti-wear and anti-fouling properties, ensuring longevity and reliability.

Our products are designed with flexibility in mind, allowing modifications to meet customer-specific requirements. We are committed to delivering H-fin tubes that are safe, reliable, and highly efficient.

The Economizer H Type Extruded Fin Tube is manufactured from diverse materials such as copper and stainless steel, catering to a wide range of application needs. Thanks to the low fin design, these tubes remain compact and lightweight, making them perfect for installations where space is at a premium.

This versatile finned tube is an ideal choice for air coolers, radiators, and numerous other heat exchanger applications. Our advanced manufacturing process ensures that each tube is meticulously crafted with precise dimensions and tight tolerances, enabling flawless integration into existing systems.

Product Details

Advantages of the H-Finned Tube:

The H-finned tube is the quintessential heat exchange component in the entire exhaust gas boiler system. It stands out with the following remarkable advantages:

(1) Superior Wear Resistance

The H-finned tube heat exchanger is meticulously arranged in a linear fashion. Its innovative design, featuring H fins, strategically divides the space into several compact areas, effectively balancing the airflow. Compared to traditional smooth tube heat exchangers with staggered layouts and spiral finned models, the H-finned tube boasts an impressive wear life that is 3 to 4 times longer under equivalent conditions.

(2) Minimized Fouling

The occurrence of fouling is typically observed on the dorsal and windward sides of the tube. Thanks to its staggered arrangement, the tube bundle is easily flushed, resulting in minimal fouling on the backside. With optimal wind speed, these tubes offer an excellent self-cleaning mechanism. Straight channels formed on both sides of the H-finned tube ensure optimal soot removal when using a soot blower.

(3) Reduced Exhaust Gas Resistance

H fins create straight channels on both sides, and the spiral angle of spiral fins guides airflow direction. Unlike spiral fins that are prone to fouling and offer higher flue resistance, H fins ensure smooth airflow with less resistance. Adopting H-finned tubes significantly reduces wind resistance, decreases fan operation, and lowers investment costs.

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

Featuring a unique patented zigzag structure, H fins achieve an impressive weld fusion rate of 98% or more with steel pipes. This ensures an outstanding heat transfer coefficient for H-finned tubes.

(5) Compact Structure, High Heat Efficiency

The heating area per unit length is remarkably large, with the H-finned tube offering a 7.8-fold increase compared to smooth tubes. All butt welds are executed with argon arc welding, vastly improving welding quality over manual methods. With significantly reduced equipment size and weight, equipment investment costs are substantially lowered, and more space is available for users during installation.

(6) Shock-Proof and Noise Reduction

Thanks to its thoughtfully engineered structural design and the inherent characteristics of the H-finned tube, the equipment also serves as a highly efficient muffler.

(7) Easy Installation, Operation, and Maintenance

Installation is simplified—simply connect the equipment to the exhaust gas outlet of HFO engine units for immediate operation. The exhaust gas boiler features a check door to determine the optimal cleaning cycle based on real-time conditions, ensuring effective heat transfer and prolonged equipment lifespan.
