Product Description

Description of H-fin boiler Finned Tubes

The innovative heat transfer solution for boilers, the H-shaped fin tubes, features an advanced construction where two pieces of steel with central arcs are symmetrically welded onto the raw tube. This unique configuration resembles the letter 'H', thus earning its name, the H-finned tube. Designed for excellence, the fins of the H-finned tube boast a rectangular, nearly square shape. Their impressive length, approximately twice the diameter of the tube, provides an extended heating surface that is perfect for efficient heat transfer. Elevating efficiency further, the H-finned tube is also available as a 'double H' finned tube, ideal for longer tube rows. This variation offers robust structural integrity and enhanced performance.

The H fin tube stands as a cornerstone in recovering waste heat from power station boilers, industrial boilers, kilns, and marine power plants. By optimizing fuel utilization, it effectively enhances the heat exchange process, positioned strategically at the tail end of the system flue.

Detail

H-type finned tube heat exchangers are engineered for optimal performance, boasting high heat transfer capacities. Their exceptional self-cleaning characteristics and flue gas waste heat recovery abilities make them indispensable in boiler retrofits. The convective heat transfer coefficient is tailored by adjusting the fin pitch. It's a delicate balance, as it inversely correlates with fin height and width, allowing for customizable heat transfer efficiency. Overall heat transfer prowess is influenced by fin efficiency, the convective heat transfer coefficient, and the finned ratio, all collaboratively enhancing performance. As fin height and width increase, so does the pressure drop, an important consideration in optimizing the design for specific applications.

H-type finned tubes are becoming increasingly popular for their ability to boost heat exchange efficiency and extend surface heat transfer. They are widely adopted in boilers and waste heat recovery systems nowadays. The modern H-type finned tubes are largely an evolution of rectangle finned tubes, offering improved efficiency and adaptability. Unique groove structures on the fin surface endow H-type finned tubes with outstanding anti-wear and anti-fouling properties, ensuring longevity and reliability.

Our products are tailored to meet customer-specific needs and scenarios. We pride ourselves on designing and manufacturing H-fin tubes that are safe, reliable, and highly efficient.

Economizer H Type Extruded Fin Tubes are versatile, available in materials like copper and stainless steel to suit diverse application demands. With a low fin design, these tubes are compact and lightweight, perfect for installations where space is limited.

Designed for versatility, this finned tube excels in air coolers, radiators, and various other heat exchanger applications, making it a top choice for engineers. Our meticulous manufacturing process ensures these tubes meet precise dimensions and tight tolerances, allowing seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube is the primary component in the exhaust gas boiler for optimal heat exchange, boasting several outstanding advantages.

(1) Excellent wear resistance

This remarkable heat exchanger with H fins is aligned in a precise line pattern, dividing the space into smaller, more manageable areas. This design ensures uniform airflow, offering superior durability compared to traditional smooth or spiral finned heat exchangers, achieving wear life that is 3 to 4 times longer.

(2) Fouling reduced

Fouling typically occurs on both the back and windward sides of the tube. Thanks to its staggered tube arrangement, the tube bundle is easily cleansed, resulting in reduced fouling on the backside. With optimal wind speeds, it showcases an impressive self-cleaning capability. Straight channels formed on the sides of the H finned tube effectively manage soot, achieving superior results when using a soot blower.

(3) Reduce the resistance of exhaust gas

Straight channel formation by H fins, coupled with spiral angles directing airflow, minimizes fouling and flue resistance compared to spiral fins. Utilizing H-finned tubes effectively reduces wind resistance, leading to decreased fan operation and lowered investment costs.

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

The innovative zigzag structure of H fins (patented) ensures a remarkable weld fusion rate of 98% or higher for fins and steel pipes, guaranteeing an exceptional heat transfer coefficient.

(5) Compact structure, high heat efficiency

Boasting a heating area per unit length 7.8 times greater than a smooth tube, the H finned tube employs argon arc welding, significantly enhancing weld quality over manual welding. This results in a notable reduction in equipment size and weight, significantly lowering investment costs and offering ample space for equipment installation.

(6) Shock-proof and noise reduced

The advanced structural design and characteristics of the H finned tube imbue the equipment with muffling properties, effectively reducing noise and shock.

(7) Convenient for installation, operation and maintenance

Installation is straightforward, requiring a mere connection to the exhaust gas outlet of HFO engine units for immediate operation. Equipped with a check door, the exhaust gas boiler allows for easy determination of cleaning cycles based on real-time conditions, ensuring optimal heat transfer and prolonged equipment lifespan.
