Product Description

Enthralling Overview of Premium H-fin Boiler Finned Tubes

Our cutting-edge boiler heat transfer tubes feature innovative H-shaped fin tubes. These tubes are meticulously crafted by symmetrically welding two steel pieces with elegant arcs onto the raw tube, resulting in distinctive fins (ribs). This unique architectural design resembles the 'H' letter, giving rise to the name H-finned tube. The sophisticated H-finned tube flaunts rectangular fins, nearly square in shape, stretching approximately twice the tube diameter, offering an extended and highly effective heating surface. For enhanced structural integrity, these H-finned tubes can be engineered into 'double H' configurations with double-tube designs, providing robust stability for extended tube rows.

Our signature H fin tube excels in reclaiming gas waste heat from power station boilers, industrial boilers, kilns, marine power plants, and more. It significantly boosts fuel efficiency while strategically positioned at the tail of system flues for optimal heat exchange.

 

Comprehensive Detail

 

H-type finned tube heat exchangers are renowned for their impressive heat transfer capacity, exceptional self-cleaning abilities, and adeptness at recycling flue gas waste heat, particularly in boiler renovations. The convective heat transfer coefficient is directly linked to fin pitch and inversely linked to both fin height and width, ensuring optimal performance. Overall heat transfer prowess is intricately tied to fin efficiency, convective heat transfer coefficients, and a calculated finned ratio. An increase in fin height and width leads to a corresponding rise in pressure drop, necessitating careful consideration in design.

 

To amplify heat exchange efficiency and augment surface heat transfer, H-type finned tubes have gained widespread application in modern boilers and waste heat recovery systems. H-type finned tubes are largely evolved from traditional rectangle finned tubes, offering advanced performance. Thanks to their distinctive grooved fin surface, H-type finned tubes boast remarkable anti-wear and anti-fouling properties, ensuring long-lasting durability.

 

Tailored to meet specific demands, our products promise safe, reliable, and efficient performance. We excel in designing and manufacturing bespoke H-fin tubes that perfectly match customer specifications.

 

The versatile Economizer H Type Extruded Fin Tube is available in a variety of materials, such as copper and stainless steel, catering to diverse application needs. Designed for compactness and lightness, its low fin design makes it an ideal choice for installations where space considerations are paramount.

 

This versatile finned tube adapts seamlessly to air coolers, radiators, and a host of other heat exchanger applications. Crafted with precision, the manufacturing process guarantees exact dimensions and tight tolerances, ensuring flawless integration into any existing system.

Advantages of H-finned tube:

 

The H-finned tube is the centerpiece of heat exchange within any comprehensive exhaust gas boiler system. Its design and construction offer numerous advantages that elevate its performance.

 

(1) Excellent wear resistance

 

Engineered for endurance, the H-finned tube heat exchanger is meticulously arranged in a linear configuration. This design partitions the space into several compact zones, effectively equalizing airflow. In comparison to the traditional smooth tube heat exchangers with staggered rows or spiral finned variants, the H-finned tube showcases a wear life that surpasses these alternatives by a remarkable 3 to 4 times.

 

(2) Fouling reduced

 

Fouling typically develops on both the dorsal and windward sides of tube surfaces. The staggered tube configuration facilitates efficient flushing of the tube bundle, thereby minimizing fouling buildup on the rear side. With an optimized wind speed, the system exhibits an exceptional self-cleaning capability. Straight channels are formed along the sides of the H-finned tube, enhancing the soot removal efficiency. The use of a soot blower maximizes the cleaning effect, ensuring optimal performance.

 

(3) Reduce the resistance of exhaust gas

 

The H fins create direct channels on either side, while the spiraled angle of spiral fins directs airflow. Consequently, unlike the greater flue resistance seen in spiral fins, H fins are less prone to fouling. Implementing H-finned tubes significantly reduces wind resistance, leading to lowered operational demands on fans, and a reduction in associated costs.

 

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

 

The distinct zigzag structure of H fins (patented) ensures a weld fusion rate between fins and steel pipes of over 98%, guaranteeing an impressive heat transfer coefficient.

 

(5) Compact structure, high heat efficiency

 

Featuring an expansive heating area per unit length, the H-finned tube boasts a ratio 7.8 times greater than that of smooth tubes. The argon arc welding of butt welds achieves a quality far superior to manual welding. Substantially lighter and more compact, the equipment allows for reduced investment in the heat transfer surface and offers users expanded space for installation.

 

(6) Shock-proof and noise reduced

 

Thanks to its innovative structural design and the inherent characteristics of the H finned tube, the equipment doubles as a muffler, providing both shock absorption and noise reduction.

 

(7) Convenient for installation, operation and maintenance

 

Installation is seamless, requiring only the connection of equipment to the exhaust gas outlet of HFO engine units to commence normal operations. Equipped with a check door, the exhaust gas boiler allows for flexible cleaning cycles based on actual conditions, thus maintaining heat transfer efficiency and extending working life.
