Product Description

Description of H-fin boiler Finned Tubes

The innovative heat transfer tube of the boiler employs H-shaped fin tubes. This design is achieved by symmetrically welding two pieces of steel with arcs in the middle onto the raw tube. This creates a distinctive "H" shape, thus earning its name: the H-finned tube. With rectangular fins that are approximately square, the H-finned tube boasts fins that extend about twice the diameter of the tube. This design significantly enhances the heating surface area, optimizing heat exchange. Offering versatility, the H-finned tube can be crafted into a "double H" finned tube configuration for double-tube structures. This design provides robust rigidity, making it ideal for longer rows of tubes.

The H fin tube is expertly utilized to recover gas waste heat in power station boilers, industrial boilers, kilns, and ship power plants, among others. It significantly boosts fuel utilization efficiency, positioning the heat exchange element effectively at the system flue's end.

Detail

Our H-type finned tube heat exchanger elements are engineered to deliver exceptional heat transfer capacity. They feature superior self-cleaning properties and are adept at recovering flue gas waste heat, making them perfect for boiler renovations. The convective heat transfer coefficient is directly proportional to the fin pitch, while it decreases as fin height and fin width increase. The overall heat transfer capacity is influenced by fin efficiency, the convective heat transfer coefficient, and the finned ratio, ensuring optimal performance. As fin height and fin width increase, so does the pressure drop, necessitating careful design considerations.

To elevate heat exchange efficiency and maximize surface heat transfer, H-type finned tubes have seen widespread application in boilers and waste heat recovery systems in recent years. The design of H-type finned tubes is largely inspired by rectangular finned tubes, offering enhanced performance. Thanks to their unique groove structure on the fin surface, H-type finned tubes exhibit outstanding anti-wear and anti-fouling capabilities.

We take pride in tailoring our products to meet our customers' specific needs. Our design and manufacturing processes ensure the creation of safe, reliable, and efficient H-fin tubes.

The Economizer H Type Extruded Fin Tube is available in a range of materials, such as copper and stainless steel, to meet diverse requirements. Its low fin design ensures the finned tube is both compact and lightweight, perfect for installations where space is at a premium.

This versatile finned tube is designed for use in air coolers, radiators, and various heat exchanger applications. Our meticulous manufacturing process ensures precise dimensions and tight tolerances, guaranteeing seamless integration into existing systems.

Product Details

Outstanding Advantages of the H Rectangular Finned Tube:

The H Rectangular Finned Tube serves as the pivotal heat exchange element within the entire exhaust gas boiler system, distinguished by several superior advantages.

(1) Exceptional Wear Resistance

Unlike the staggered arrangement of smooth tube heat exchangers or spiral finned exchangers, the H Finned Tube Heat Exchanger features a direct in-line configuration. This strategic design divides the space into smaller sections, promoting even air distribution. Consequently, under identical conditions, its wear life is remarkably enhanced, lasting 3 to 4 times longer.

(2) Significantly Reduced Fouling

Fouling typically forms on both the dorsal and windward sides of tubes. With the staggered tube arrangement, tube bundles are efficiently flushed, resulting in minimal fouling on the backside. Boasting an impressive self-cleaning function, this feature becomes evident under optimal wind speeds. On either side of the H Finned Tube, straight channels are formed, which, when utilized with a soot blower, achieve superior soot removal.

(3) Minimized Exhaust Gas Resistance

H Fins, with their straight channel design, significantly guide airflow, unlike spiral fins which increase flue resistance and are more prone to fouling. Implementing H Finned Tubes decreases wind resistance, thereby cutting down on fan operation and associated investment costs.

(4) Superior Welding Fusion Rate

Thanks to the unique zigzag (patented) configuration of the H Fins, the welding fusion rate with steel pipes reaches an outstanding 98% or more, ensuring top-notch heat transfer efficiency.

(5) Compact and High-Efficiency Design

The H Finned Tube delivers an expansive heating area per unit length, 7.8 times that of a smooth tube. Utilizing argon arc welding for butt welds, the quality surpasses that of manual welding substantially. With reduced equipment size and weight, the same heat transfer surface equates to minimized investment, providing users with more space for installation.

(6) Vibration and Noise Reduction

The innovative design and structural attributes of the H Finned Tube incorporate muffler characteristics, enabling the equipment to function effectively as a silencer.

(7) Effortless Installation, Operation, and Maintenance

During installation, simply connect the equipment to the exhaust gas outlet of HFO engine units for seamless operation. Equipped with an inspection door, the exhaust gas boiler allows for customized cleaning cycles based on real-time conditions, ensuring optimal heat transfer and prolonging equipment lifespan.
