Product Description

Description of H-fin Boiler Finned Tubes

The cutting-edge heat transfer tube of the boiler employs H-shaped fin tubes, ingeniously engineered by welding two arched steel pieces onto the raw tube. This innovative design, resembling the letter "H", crafts fins with unmatched efficiency, hence the name H-finned tube. The H-finned tube boasts rectangular, nearly square fins that extend to approximately twice the diameter of the tube itself, significantly enhancing the heating surface for optimal performance. For even greater structural rigidity and length adaptability, the H-finned tube can be crafted into a "double H" finned tube, making it ideal for longer tube arrangements.

The H fin tube excels in reclaiming gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants. This improves fuel efficiency remarkably, with the heat exchange element strategically positioned at the flue system's tail.

Detail

H-type finned tube heat exchanger elements exhibit exceptional heat transfer capacity, outstanding self-cleaning attributes, and are ideal for flue gas waste heat recovery during boiler refurbishments. The convective heat transfer coefficient intricately hinges on fin pitch, while inversely depending on fin height and width, ensuring efficient heat exchange dynamics. The overall heat transfer capacity is elegantly influenced by fin efficiency, the convective heat transfer coefficient, and the ratio of finned surfaces. An increase in fin height and width correlates with a rise in pressure drop, highlighting the balance needed for optimal performance.

To enhance heat exchange efficiency and increase surface heat transfer, H-type finned tubes have become a staple in boiler systems and waste heat recovery initiatives in recent years. Predominantly derived from rectangular finned tubes, H-type finned tubes offer an advanced solution with enhanced capabilities. Featuring a distinctive groove structure on the fin surface, H-type finned tubes deliver superior anti-wear and anti-fouling performance, setting a benchmark in durability.

Our versatile products can be tailored to meet client-specific needs, ensuring that our H-fin tubes are designed and manufactured with the utmost safety, reliability, and efficiency.

The Economizer H Type Extruded Fin Tube is offered in a range of materials, including copper and stainless steel, to satisfy diverse application demands. Its low fin design ensures that the tube is both compact and lightweight, making it the perfect choice for installations with space limitations.

This versatile finned tube is perfectly suited for a variety of applications such as air coolers, radiators, and numerous heat exchanger systems. With a meticulous manufacturing process, we ensure precise dimensions and tight tolerances for seamless integration into existing systems, guaranteeing optimal performance.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the pivotal element of heat exchange within the entire exhaust gas boiler system. It boasts the following outstanding features:

(1) Excellent wear resistance

Strategically arranged in line, the H-finned tube heat exchanger utilizes its fins to demarcate the space into multiple small segments, harmonizing airflow. Compared to smooth tube exchangers with staggered layouts or spiral finned counterparts, the H-fin design dramatically extends wear life by 3 to 4 times under comparable conditions.

(2) Fouling reduced

Fouling typically accumulates on the dorsal and windward surfaces of the tube. With the tube's staggered configuration, the bundle is easily flushed, minimizing back-side fouling. This system effectively self-cleans at optimal wind speeds. The H-finned tube's straight channel design optimizes soot removal, especially when a soot blower is employed, ensuring premium soot control.

(3) Reduce the resistance of exhaust gas

The straight channels formed by the H fins and the airflow steering facilitated by the spiral angle of spiral fins reduce fouling and flue resistance, outperforming H fins. Utilizing H-finned tubes significantly cuts down on wind resistance, leading to lower operational costs for fans and reduced capital expenditure.

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

With a unique zigzag pattern, the H fins achieve an impressive weld fusion rate of 98% or higher with steel pipes, ensuring optimal heat transfer efficiency.

(5) Compact structure, high heat efficiency

Boasting a sizeable heating area per unit length—7.8 times that of a smooth tube—the H-finned tube's design includes all butt welds executed via argon arc welding, surpassing manual welding quality. This compact setup not only reduces the equipment's size and weight but also slashes investment costs, offering users ample installation space. With a significant decrease in both equipment size and weight, this design minimizes investment while maximizing installation space for the user.

(6) Shock-proof and noise reduced

Thanks to the inventive structural design and the distinctive features of the H-finned tube, the equipment additionally acts as a muffler, ensuring reduced noise.

(7) Convenient for installation, operation, and maintenance

Installation is streamlined; simply connect the unit to the exhaust gas outlet of HFO engine units for immediate operation. Equipped with a check door, the exhaust gas boiler allows maintenance cycles to be tailored based on real-time conditions, ensuring optimal heat transfer and extending the equipment's lifespan.
