Product Description

Description of H-fin Boiler Finned Tubes

The innovative heat transfer tube of the boiler features the remarkable H-shaped fin tubes. These are crafted by symmetrically welding two pieces of steel, designed with elegant arcs in the center, onto a raw tube to create the fins. This configuration miraculously resembles the letter 'H,' earning it the name H-finned tube, a true engineering marvel in heat transfer solutions. The fins on the cutting-edge H-finned tube are meticulously crafted to be rectangular, closely resembling a square. Their length is ingeniously about twice the diameter of the tube, providing an extended heating surface that maximizes thermal efficiency. The H-finned tube can be ingeniously configured into a 'double H' finned tube, featuring a robust double-tube structure. This design offers impressive rigidity, making it ideal for applications requiring a longer row of tubes, providing unparalleled stability and performance.

The H fin tube serves as an efficient solution for recovering gas waste heat in diverse applications such as power station boilers, industrial boilers, kilns, and marine power plants. It significantly enhances fuel utilization rates, with the heat exchange elements strategically positioned at the tail of the system flue for optimal performance.

Detail

H-type finned tube heat exchanger elements are engineered to maintain exceptional heat transfer capabilities. They boast superior self-cleaning properties, making them an excellent choice for flue gas waste heat recovery during boiler renovations, ensuring long-term efficiency. The convective heat transfer coefficient of this advanced design is intricately linked to the fin pitch, while inversely related to the fin height and width, allowing for precise thermal management. Integrated heat transfer capacity hinges on fin efficiency, the convective heat transfer coefficient, and the finned ratio, promising superior heat exchange performance. Pressure drop is directly affected by increases in fin height and width, a critical consideration for optimizing system performance and efficiency.

To elevate heat exchange efficiency and surface heat transfer, H-type finned tubes have seen expansive use in boilers and waste heat recovery systems in recent years, a testament to their outstanding performance. H-type finned tubes owe their development largely to the innovative designs of rectangle finned tubes, enhancing their versatility and application reach. With a unique groove structure on the fin surface, H-type finned tubes exhibit exceptional anti-wear and anti-fouling properties, making them a resilient choice for demanding environments.

Our products are meticulously designed and manufactured to be safe, reliable, and efficient. We offer customization to meet specific customer needs, ensuring our H-fin tubes exceed expectations.

Product Details

Advantages of H-finned tube:

The H-finned tube serves as the pivotal heat exchange component within the entire exhaust gas boiler. This innovative tube boasts an array of remarkable advantages that elevate its performance to unparalleled heights.

(1) Excellent wear resistance

Ingeniously designed, the H finned tube heat exchanger aligns in a linear fashion, with H fins artfully segmenting the space into numerous compact zones. This sophisticated design harmonizes airflow, making it vastly superior to the staggered or spiral finned counterparts. When compared under similar conditions, its wear life impressively extends 3 to 4 times longer.

(2) Fouling reduced

Fouling typically occurs on the dorsal and windward sides of the tube. Thanks to its staggered arrangement, the tube bundle is easily cleansed, minimizing fouling on the backside. It boasts a remarkable self-cleaning capability at optimal wind speeds, ensuring sustained efficiency. Crafted with precision, the H finned tube forms straight channels on either side, excelling in soot management. Coupled with a soot blower, it achieves optimal soot removal.

(3) Reduce the resistance of exhaust gas

The ingenious creation of straight channels by the H fins, along with the spiral angle steering airflow, minimizes fouling. This design ensures lesser flue resistance compared to traditional spiral fins, optimizing performance. The integration of H-finned tubes dramatically lowers wind resistance, reducing the operational demands and associated costs of the fan system.

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

Owing to the distinctive patented zigzag structure of the H fins, the weld fusion rate with steel pipes soars to an impressive 98% or more, guaranteeing superior heat transfer efficiency.

(5) Compact structure, high heat efficiency

With an extensive heating area per unit length, the H finned tube outshines the smooth tube by 7.8 times! Employing argon arc welding for butt welds further elevates weld quality beyond manual methods. Compact and lightweight, this cutting-edge design slashes equipment investment while offering expansive installation flexibility, creating vast opportunities for users.

(6) Shock-proof and noise reduced

Thanks to the ingenious structural design and unique attributes of the H finned tube, this equipment doubles as an effective muffler, providing quiet operation.

(7) Convenient for installation, operation and maintenance

Installing this state-of-the-art equipment is a breeze—simply connect it to the exhaust gas outlet of HFO engine units, and it's ready for seamless operation. The exhaust gas boiler is equipped with a convenient check door, allowing for tailored cleaning cycles based on real-time conditions, ensuring optimal heat transfer and extending operational lifespan.
