Product Description

Description of H-fin boiler Finned Tubes

The masterpiece of heat transfer efficiency in boilers, the H-shaped fin tubes, stand out with their innovative design. By symmetrically welding two arc-shaped steel pieces onto the raw tube, these fins, resembling the letter 'H', significantly enhance heat transfer efficiency. These fins are a marvel of precision, with a rectangular, nearly square structure. Extending roughly twice the diameter of the tube, they create an expanded heating surface that maximizes thermal performance. For even greater durability and performance, the H-finned tube can be crafted into a 'double H' design. This double-tube variant boasts an exceptionally rigid structure, making it ideal for longer tube arrays.

H fin tubes are essential for capturing and repurposing gas waste heat from diverse sources like power station boilers, industrial kilns, and marine power plants. They drastically improve fuel utilization rates and are strategically positioned at the system flue's tail for optimal efficiency.

Detail

Engineered for excellence, H-type finned tube heat exchanger components deliver robust heat transfer capabilities. They excel in self-cleaning and are pivotal in flue gas waste heat recovery during boiler upgrades. The convective heat transfer coefficient is intricately linked to the fin pitch, while inversely affected by fin height and width. This balance ensures optimized performance. The overall heat transfer prowess hinges on fin efficiency, the convective heat transfer coefficient, and the finned surface ratio, forming the cornerstone of superior heat exchange. An increase in fin height and width does lead to a rise in pressure drop, a factor carefully considered in design for optimal functionality.

With a focus on enhanced heat exchange efficiency, H-type finned tubes have become indispensable in modern boilers and waste heat recovery solutions due to their extended surface area. Evolved from their rectangular predecessors, H-type finned tubes epitomize technological advancement in finned tube design. Their distinct grooved surface ensures remarkable resistance against wear and fouling, a testament to their exceptional durability and engineering.

Tailored to perfection, our products are designed to meet specific customer requirements. We pride ourselves on crafting safe, reliable, and highly efficient H-fin tubes.

Our Economizer H Type Extruded Fin Tube selection includes various materials such as copper and stainless steel, offering versatility to meet diverse project needs.

Product Details

Advantages of H-Finned Tube:

The H-finned tube stands as the premier heat exchange component within any exhaust gas boiler. It offers myriad advantages that make it indispensable.

(1) Exceptional Wear Resistance

In a perfectly aligned configuration, the H finned tube heat exchanger artfully divides space into smaller sections, ensuring balanced airflow distribution. When compared to traditional smooth tube exchangers with staggered setups or spiral finned versions, the wear life of the H finned tube significantly surpasses, boasting an impressive 3 to 4 times longer lifespan under identical conditions.

(2) Minimized Fouling

Fouling predominantly occurs on the dorsal and windward sides of the tube. With a staggered tube arrangement, the tube bundle is efficiently flushed, significantly reducing fouling on the rear side. At optimal wind speeds, the tube demonstrates an admirable self-cleaning ability. The straight channels formed on either side of the H finned tube are particularly effective for soot management, achieving peak soot control when combined with a soot blower.

(3) Lower Exhaust Gas Resistance

The straight channels crafted by the H fins, coupled with the spiral angle steering of airflow, mean the H fins are less prone to fouling and present lesser flue resistance compared to their spiral fin counterparts. Thus, employing H-finned tubes not only minimizes wind resistance but also curtails operational costs associated with fan usage.

(4) High Fusion Weld Rate

Thanks to the patented zigzag design of the H fins, the welding fusion rate between fins and steel pipes reaches an impressive 98% or more. This design ensures an outstanding heat transfer coefficient for the H-finned tubes.

(5) Efficient and Compact Architecture

Featuring a substantial heating area per unit of length—7.8 times greater than that of a smooth tube—the H finned tube utilizes argon arc welding for its butt welds, significantly enhancing welding quality over manual methods. The equipment's reduced size and weight lead to significantly lower equipment investment for the same heat transfer surface, offering users increased installation space flexibility.

(6) Vibration and Noise Reduction

The innovative structural design of the H finned tube incorporates muffler characteristics, enabling the equipment to effectively function as a noise-reducing solution.

(7) Ease of Installation, Operation, and Maintenance

Installation is straightforward—simply connect the equipment to the exhaust gas outlet of HFO engine units for seamless operation. Equipped with a check door, the exhaust gas boiler allows for cleaning cycles to be determined based on actual conditions, ensuring optimal heat transfer and prolonging operational longevity.
