Product Description

Description of H-fin Boiler Finned Tubes

The heat transfer tube of the boiler employs the innovative H-shaped fin tubes. This design features two intricately welded steel pieces with arcs in the middle. They are symmetrically attached to the raw tube, creating prominent fins (ribs) that resemble the majestic letter 'H'. This unique structure earns it the name: H-finned tube. The H-finned tube boasts fins that are rectangular, nearly square in shape, with a length that approximately doubles the diameter of the tube, thereby significantly enhancing the heating surface area. The H-finned tube can be upgraded to the 'double H' finned tube configuration, featuring a robust double-tube setup. This offers exceptional rigidity and is ideal for applications involving longer tube rows.

H fin tubes are adept at recovering gas waste heat from power station boilers, industrial boilers, kilns, ship power plants, and more. They substantially elevate the efficiency of fuel utilization, serving as pivotal heat exchange elements strategically positioned at the system flue's tail.

Detail

H-type finned tube heat exchanger components exhibit an extraordinary capacity for heat transfer. Their superior self-cleaning characteristics enhance their efficacy in capturing flue gas waste heat during boiler upgrades. The convective heat transfer coefficient increases with fin pitch but decreases with larger fin height and width, ensuring optimal thermal performance. Overall heat transfer capacity is intricately linked to fin efficiency, the convective heat transfer coefficient, and the finned ratio, creating an advanced thermal management system. An increase in fin height and width correlates with a rise in pressure drop, a crucial consideration for system design.

To maximize heat exchange efficiency and extend surface heat transfer, H-type finned tubes have become the preferred choice for modern boilers and cutting-edge waste heat recovery systems. H-type finned tubes evolve from the classic rectangle finned tubes, offering enhanced performance and durability. Thanks to their distinctive groove structure on the fin surface, H-type finned tubes excel in anti-wear and anti-fouling capabilities.

Our expertly crafted products are tailored to meet specific customer requirements. We design and manufacture H-fin tubes that are safe, reliable, and efficient, catering to diverse industrial needs.

The Economizer H Type Extruded Fin Tube is available in a variety of materials, including copper and stainless steel, to meet diverse application requirements. The innovative low fin design ensures these tubes are compact and lightweight, making them ideal for installations with space constraints.

This versatile finned tube is perfectly suited for use in air coolers, radiators, and other heat exchanger applications, providing exceptional thermal efficiency. Our meticulous manufacturing process ensures these finned tubes have precise dimensions and tight tolerances, facilitating seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the cornerstone of heat exchange within an exhaust gas boiler, offering a range of remarkable benefits.

(1) Excellent wear resistance

Ingeniously designed, the H finned tube heat exchanger is aligned perfectly in line. This clever arrangement of H fins creates multiple small chambers that homogenize the airflow. Compared to other heat exchangers with staggered tubes or spiral fins, this design offers superior wear resistance, lasting 3 to 4 times longer under similar conditions.

(2) Fouling reduced

Fouling typically occurs at the dorsal side and the windward side of the tube. A staggered tube arrangement facilitates the easy flushing of the tube bundle, leading to significantly reduced fouling on the backside. At optimal wind speeds, it boasts an impressive self-cleaning ability. Straight channels formed on both sides of the H-finned tube efficiently manage soot, achieving optimal cleanliness with the use of a soot blower.

(3) Reduce the resistance of exhaust gas

Thanks to the straight channels formed by the H fins and the airflow orientation provided by the spiral angle of spiral fins, H fins demonstrate lower susceptibility to fouling and reduced flue resistance compared to their spiral counterparts. Thus, adopting H-finned tubes can significantly decrease wind resistance, consequently lowering both operational costs and fan investment expenses.

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

The patented zigzag structure of H fins ensures an exceptional weld fusion rate of 98% or more with steel pipes, guaranteeing an excellent heat transfer coefficient for H-finned tubes.

(5) Compact structure, high heat efficiency

Boasting a heating area per unit length that is 7.8 times larger than a smooth tube, the H-finned tube features high-quality argon arc welding butt welds, surpassing manual welding standards. This results in significantly reduced equipment size and weight, cutting down on investment costs while providing ample installation space. With reduced equipment dimensions and weight, investment costs diminish, offering users greater flexibility and space during equipment installation.

(6) Shock-proof and noise reduced

Due to its thoughtful structural design, the H-finned tube possesses sound-dampening characteristics, enabling the equipment to function effectively as a muffler.

(7) Convenient for installation, operation and maintenance

Installation is simplified—just connect the equipment to the exhaust gas outlet of the HFO engine units, and it's ready for operation. The exhaust gas boiler includes a check door, allowing for the adjustment of cleaning cycles based on actual conditions to maintain optimal heat transfer and extend the equipment's lifespan.
