Product Description

Overview of the H-Fin Boiler Finned Tubes

Our advanced boiler heat transfer solution utilizes the innovative H-shaped fin tubes. Featuring an H-like profile, they are crafted by symmetrically welding two arced steel strips onto the base tube, resulting in efficient fins (ribs). This design not only optimizes heat transfer but exemplifies engineering excellence, earning it the name, H-finned tube. These state-of-the-art H-finned tubes boast rectangular fins that are nearly square in shape, extending to about twice the diameter of the tube. This design significantly increases the available heating surface area, ensuring heightened heat exchange capability. Our H-finned tubes can be innovatively transformed into 'Double H' finned tubes, featuring a dual-tube design with enhanced structural rigidity. This makes them ideal for longer tube assemblies, providing unmatched durability and performance.

H fin tubes are indispensable in reclaiming gas waste heat across various sectors, including power station boilers, industrial boilers, kilns, and marine power plants. They amplify fuel utilization rates and serve as efficient heat exchange elements strategically positioned at the system flue’s tail end.

Specifications and Features

The H-type finned tube heat exchanger components deliver exceptional heat transfer capabilities, outstanding self-cleaning properties, and are pivotal in recycling flue gas waste heat during boiler upgrades, ensuring efficiency and sustainability. The convective heat transfer coefficient is intricately linked to fin pitch, while inversely affected by fin height and width, underscoring the precision required in their design. The comprehensive heat transfer capacity of H-type fins is determined by fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring optimal performance. Note that as fin height and width increase, the pressure drop naturally rises, emphasizing the need for meticulous engineering.

In recent years, H-type finned tubes have become widely adopted in boilers and waste heat recovery applications, thanks to their superior heat exchange efficiency and extended surface heat transfer capabilities. Derived primarily from rectangular finned tubes, H-type finned tubes offer a refined solution with enhanced thermal properties. Thanks to their unique grooved structure on the fin surface, H-type finned tubes exhibit remarkable anti-wear and anti-fouling capabilities, ensuring longevity and reliability.

Our offerings are customizable to meet specific customer requirements, ensuring that we deliver safe, reliable, and efficient H-fin tubes tailored to diverse needs.

The Economizer H Type Extruded Fin Tube is offered in a variety of materials, such as copper and stainless steel, to cater to diverse application needs and preferences. The innovative low fin design ensures compactness and reduced weight, making it the perfect choice for installations where space is at a premium.

Our finned tubes are versatile, ideal for use in air coolers, radiators, and other heat exchanger applications, meeting a wide range of industrial needs. With precision manufacturing processes, these tubes deliver exact dimensions and tight tolerances, allowing for flawless integration into existing systems.

Advantages of H-finned tube:

The H-finned tube is a crucial heat exchange component within the exhaust gas boiler system, offering an array of remarkable advantages.

(1) Outstanding wear resistance

Designed in a linear arrangement, the H-finned tube heat exchanger utilizes H fins to segment space into smaller areas, which optimizes air flow. Unlike smooth tube exchangers with staggered configurations or spiral finned exchangers, this design significantly enhances wear life by 3 to 4 times under similar conditions.

(2) Minimized fouling

Fouling typically forms on both the dorsal and windward sides of the tubes. The staggered tube arrangement facilitates easy cleaning of the tube bundle, resulting in reduced fouling on the back side. At optimal wind speeds, the tubes exhibit excellent self-cleaning properties. Straight channels on both sides of the H finned tubes allow for efficient soot collection, achieving optimal soot removal when combined with a soot blower.

(3) Less exhaust gas resistance

With the H fins creating straight channels and the spiral fins guiding airflow direction, H fins are less prone to fouling and offer lower flue resistance compared to spiral fins. Thus, employing H-finned tubes minimizes wind resistance, thereby decreasing fan operational costs and investment.

(4) High welding fusion rate between fins and steel pipe

Thanks to the unique, zigzag (patented) structure of the H fins, the welding fusion rate between fins and steel pipes exceeds 98%, ensuring an excellent heat transfer coefficient for the tubes.

(5) Compact structure with superior heat efficiency

The extensive heating area per unit length of the H finned tube is 7.8 times greater than that of a smooth tube. The butt welds are executed using argon arc welding, significantly improving welding quality over manual methods. This reduction in equipment size and weight leads to a substantial decrease in equipment investment, while simultaneously providing users with more installation space.

(6) Vibration-proof and noise reduction

Owing to its structural design, the H finned tube exhibits muffler-like characteristics, enabling the equipment to function as a noise reducer.

(7) Easy installation, operation, and maintenance

Installation is streamlined; simply connect the equipment to the exhaust gas outlet of HFO engine units to commence normal operations. The exhaust gas boiler is equipped with an inspection door, allowing the cleaning cycle to be adjusted based on real-world conditions, thereby ensuring optimal heat transfer and extending operational life.
