Product Description

Description of H-fin Boiler Finned Tubes

The innovative design of our boiler's heat transfer tube features the distinctive H-shaped fin tubes. This design involves expertly welding two steel pieces with arcs onto the raw tube to create symmetrical fins, resembling the shape of the letter 'H'. Hence, they are aptly named H-finned tubes, providing superior heat transfer efficiency. Our H-finned tubes boast rectangular fins that are approximately square and measure about twice the tube's diameter. This design results in an extended heating surface, significantly enhancing heat exchange. The versatility of H-finned tubes extends to the production of 'double H' finned tubes, featuring a dual-tube configuration. This design offers excellent structural rigidity, making it ideal for longer tube rows.

H fin tubes are indispensable in recovering waste heat from power station boilers, industrial boilers, kilns, ship power plants, and more. They substantially improve fuel utilization and are strategically placed at the system flue's tail as key heat exchange elements.

Detail

Our H-type finned tube heat exchanger elements are designed for high heat transfer capacity, outstanding self-cleaning properties, and efficient flue gas waste heat recovery, especially beneficial in boiler renovations. The convective heat transfer coefficient increases with greater fin pitch, yet it inversely correlates with fin height and width, ensuring tailored heat exchange solutions. A tube's overall heat transfer capacity is determined by its fin efficiency, the convective heat transfer coefficient, and the finned ratio, optimizing performance across applications. It's important to note that pressure drop escalates with increased fin height and width, which must be considered for efficient system integration.

To maximize heat exchange efficiency and expand surface heat transfer, our H-type finned tubes have become integral to modern boilers and waste heat recovery systems. The H-type finned tubes we offer are largely derived from their rectangular finned counterparts, ensuring a distinguished performance. Featuring a unique groove structure on the fin surface, our H-type finned tubes excel in anti-wear and anti-fouling performance, ensuring longevity and reliability.

Our adaptable products can be customized to meet specific customer requirements, ensuring the design and manufacturing of safe, reliable, and efficient H-fin tubes.

The Economizer H Type Extruded Fin Tube is available in a variety of materials, including copper and stainless steel, to meet diverse application requirements. Its low fin design ensures a compact and lightweight structure, ideal for installations where space is at a premium.

Perfect for air coolers, radiators, and other heat exchanger applications, this versatile finned tube delivers top-notch performance. The meticulous manufacturing process ensures precise dimensions and tight tolerances, guaranteeing seamless integration into existing systems for optimal performance.

Product Details

Advantages of H-finned tube:

The H-finned tube is the principal heat exchange component within the exhaust gas boiler system. It offers remarkable benefits that make it a superior choice for high-performance applications.

(1) Excellent wear resistance

In a meticulously arranged line, the H-finned tube heat exchanger excels by separating spaces into multiple small areas. This unique design optimizes air flow distribution, resulting in a wear life that is 3 to 4 times greater than that of traditional smooth tube heat exchangers, staggered arrangements, or spiral finned heat exchangers.

(2) Fouling reduced

Fouling is commonly observed on the dorsal and windward sides of tubes. The strategic staggered arrangement of tubes facilitates easy flushing of the tube bundle, significantly minimizing fouling on the backside. It also features an impressive self-cleaning function when operated at an optimal wind speed. The straight channels formed on both sides of the H-finned tube efficiently manage soot, achieving optimal soot removal when using a soot blower.

(3) Reduce the resistance of exhaust gas

The straight channels created by H fins guide airflow effectively, reducing the flue resistance significantly compared to spiral fins, which are more susceptible to fouling. Thus, the H-finned tube lowers wind resistance, consequently reducing both fan operational costs and initial investment expenses.

(4) Fins and steel pipe welding fusion rate is high

Thanks to a patented, unique zigzag structure, the H fins achieve a welding fusion rate with the steel pipes of 98% or higher, ensuring exceptional heat transfer efficiency.

(5) Compact structure, 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 executed using argon arc welding, significantly enhancing the quality compared to manual welding. The compact size and reduced weight of the equipment substantially cut investment costs and provide ample space for users during installation, all while maintaining the same heat transfer surface area.

(6) Shock-proof and noise reduced

Thanks to its innovative structural design, the H-finned tube functions as an effective muffler, reducing noise and providing shock-proof benefits.

(7) Convenient for installation, operation and maintenance

Installation is straightforward, requiring only a connection to the exhaust gas outlet of HFO engine units for seamless operation. The exhaust gas boiler is equipped with an inspection door, allowing the cleaning cycle to be adjusted based on actual conditions, thus ensuring optimal heat transfer and extending the equipment's lifespan.
