Product Description

Exquisite Overview of the H-fin Boiler Finned Tubes

Crafted with precision, the heat transfer tube of the boiler features innovative H-shaped fin tubes. Two finely arched steel pieces are symmetrically welded onto the raw tube, forming robust fins. This meticulous design, reminiscent of the letter 'H', imparts the name H-finned tube. The fins boast a rectangular, near-square profile, extending approximately twice the tube's diameter, significantly enhancing the heating surface. For superior structural integrity, the H-finned tube can be crafted into a 'double H' finned tube, specifically designed for longer tube arrays.

Employed in recovering gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants, the H fin tube maximizes fuel utilization. This crucial heat exchange element is strategically positioned at the flue's tail end.

Intricate Specifications

Our H-type finned tube heat exchangers deliver high-efficiency heat transfer, excellent self-cleaning capabilities, and outstanding performance in boiler renovations involving flue gas waste heat recovery. The convective heat transfer coefficient is intricately linked to the fin pitch while inversely related to the fin's height and width. The comprehensive heat transfer capacity hinges on the synergy of fin efficiency, convective heat transfer coefficient, and finned ratio. Noticeably, the pressure drop correlates with the increase in fin height and width.

In recent times, H-type finned tubes have gained immense popularity in boilers and waste heat recovery for their enhanced heat exchange efficiency and extended surface heat transfer. Predominantly evolving from rectangle finned tubes, H-type finned tubes stand out with their distinctive attributes. Thanks to their unique grooved fin surface, H-type finned tubes showcase exceptional anti-wear and anti-fouling properties.

Tailored to perfection, our products are designed to meet diverse customer specifications, ensuring safe, reliable, and efficient H-fin tubes.

Our Economizer H Type Extruded Fin Tube, available in premium materials like copper and stainless steel, meets a spectrum of requirements. Engineered for compactness and lightweight, the low fin design is perfect for installations where space is a premium.

Ideal for air coolers, radiators, and other heat exchanger applications, this finned tube offers versatile solutions. Our expert manufacturing process ensures precise dimensions and tight tolerances, allowing seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the pivotal heat exchange component within the entire exhaust gas boiler system, offering an array of remarkable benefits that set it apart.

(1) Excellent wear resistance

The H finned tube heat exchanger features a strategic in-line arrangement, where the innovative H fins divide space into smaller sections, effectively balancing the airflow. When compared to smooth tube exchangers with staggered set-ups and other designs like spiral fin exchangers, the H finned tube delivers a wear life that exceeds by 3 to 4 times under identical conditions.

(2) Fouling reduced

Fouling predominantly occurs on both the dorsal and windward sides of the tube. A staggered tube arrangement facilitates effective flushing of the tube bundle, thus significantly reducing fouling on the back side. It boasts an efficient self-cleaning capability when operated at optimal wind speeds. The H finned tube design creates straight channels flanked by soot, achieving superior soot removal efficiency when paired with a soot blower system.

(3) Reduce the resistance of exhaust gas

The straight channels formed by H fins, in combination with the spiral angle of spiral fins that guide airflow direction, mean that H fins are less prone to fouling and present minimal flue resistance, unlike other fin structures. Thus, utilizing the H-finned tube effectively decreases wind resistance, thereby cutting down on fan operation and investment costs.

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

Owing to the unique patented zigzag structure of H fins, the weld fusion rate between fins and steel pipes can soar to 98% or higher, ensuring an exceptional heat transfer coefficient for H-finned tubes.

(5) Compact structure, high heat efficiency

The H finned tube offers an expansive heating area per unit length that is 7.8 times that of a smooth tube. All butt welds employ argon arc welding, which significantly enhances the weld quality over manual welding techniques. With a notable reduction in equipment size and weight, the same heat transfer surface area leads to substantially lower equipment investment, providing users with greater flexibility in installation space and overall setup.

(6) Shock-proof and noise reduced

Due to its structural design and the inherent characteristics of the H finned tube, the device also functions as an effective muffler, showcasing excellent shock-proof and noise-reducing attributes.

(7) Convenient for installation, operation and maintenance

During installation, simply connecting the equipment to the exhaust gas outlet of HFO engine units allows for immediate operational readiness; The exhaust gas boiler includes a check door, enabling the determination of cleaning cycles based on actual conditions to maintain optimal heat transfer and prolong operational lifespan.
