Product Description

Description of H-Fin Boiler Finned Tubes

The marvel of engineering, the H-shaped fin tubes transform ordinary heat transfer tubes into high-efficiency heat exchange elements. They elegantly weld two pieces of steel with arcs symmetrically onto the raw tube, creating the iconic 'H' shape. This innovative design significantly enhances heat transfer capabilities. Remarkably distinct, the fins of the H-finned tube are rectangular, nearly square, boasting a length approximately double the diameter of the tube. This configuration dramatically extends the heating surface area, maximizing thermal efficiency. The H-finned tube is also available in an advanced 'double H' configuration, utilizing a double-tube design. This provides a robust and resilient structure, ideal for applications requiring extended rows of tubes.

Our H fin tubes excel in reclaiming gas waste heat from power station boilers, industrial boilers, kilns, and marine power plants. They greatly enhance fuel utilization and are strategically placed at the system flue's tail for optimal heat recovery.

Detail

Our H-type finned tube heat exchanger elements are engineered for exceptional heat transfer capacity. They offer outstanding self-cleaning capabilities and are pivotal in flue gas waste heat recovery during boiler upgrades. The convective heat transfer coefficient is directly proportional to fin pitch, while it inversely correlates with fin height and width, ensuring precise thermal management. The overall heat transfer efficiency hinges on fin efficiency, the convective heat transfer coefficient, and the finned ratio, creating a synergy for superior thermal performance. Increased fin height and width generally result in a higher pressure drop, a critical consideration for system design and operation.

To amplify heat exchange efficiency and surface heat transfer, H-type finned tubes have become a staple in modern boilers and waste heat recovery systems. H-type finned tubes evolve primarily from rectangular finned tubes, offering enhanced performance and durability. Thanks to their distinctive groove structure, H-type finned tubes demonstrate exceptional resistance to wear and fouling, providing long-lasting reliability.

Our versatile products can be tailored to meet individual customer requirements, ensuring safe, reliable, and efficient H-fin tubes tailored to various needs.

The Economizer H Type Extruded Fin Tube is available in a range of materials, including copper and stainless steel, perfectly suited to diverse applications. Designed with a low fin, these tubes ensure a compact and lightweight form, ideal for installations where space is at a premium.

This versatile finned tube is perfect for air coolers, radiators, and a wide array of heat exchanger applications, offering unmatched adaptability. Our meticulous manufacturing process ensures precise dimensions and tight tolerances, facilitating seamless integration with pre-existing systems.

Product Details

Advantages of H-finned tube:

The H-finned tube stands as the core heat exchange element within the entire exhaust gas boiler system, offering remarkable benefits.

(1) Superior wear resistance

Designed with precision, the H finned tube heat exchanger is arranged in a straight line, with H fins segmenting the space into multiple small areas, effectively equalizing air flow. Unlike the staggered smooth tube heat exchanger and spiral finned counterparts, the wear life of this configuration boasts a durability 3 to 4 times greater under similar conditions.

(2) Reduced fouling potential

Fouling generally occurs on the dorsal and windward sides of the tube. With a staggered tube arrangement, the bundle is easily flushed, minimizing back-side fouling. The design inherently supports self-cleaning at optimal wind speeds. Straight channels formed on both sides of the H finned tube facilitate efficient soot removal, especially when employing soot blowers.

(3) Lower exhaust gas resistance

H fins, by creating straight channels, and the strategic angle of spiral fins guiding airflow directionally, result in less flue resistance compared to traditional fin designs. Adopting H-finned tubes reduces wind resistance, thereby cutting down on fan operation costs and capital investments.

(4) High weld fusion rate between fins and steel pipes

Thanks to the patented zigzag architecture of the H fins, an impressive weld fusion rate exceeding 98% is achieved, ensuring optimal heat transfer efficiency.

(5) Compact design with enhanced heat efficiency

Boasting a large heating area per unit length—7.8 times that of a smooth tube—the H finned tube uses argon arc welding for superior weld quality over manual methods. The equipment's size and weight are significantly reduced, cutting investment costs, while also providing users with more installation flexibility.

(6) Vibration and noise reduction

Engineered with a specialized structural design, the H finned tube acts as an effective muffler, promoting noise reduction.

(7) Easy installation, operation, and maintenance

Installation is straightforward—simply connect the equipment to the exhaust gas outlet of HFO engine units to commence standard operation. A check door on the exhaust gas boiler allows for cleaning cycle adjustments based on actual conditions, ensuring superior heat transfer performance and prolonged operational life.
