Product Description

Description of H-fin boiler tubes

The heat transfer tube of the boiler adopts the H-shaped fin tubes, it is to weld two pieces of steel with arcs in the middle of the arc symmetrically onto the raw tube to form the fins (ribs), the front shape is quite like the letter "H", so it is called H-finned tube. The fins of the H-finned tube are rectangular, approximately square, with a length of about 2 times the diameter of the tube and an extended heating surface. H-finned tube can also be made into "double H" finned tube of double-tube, with good rigidity structure, it can be applied to the longer row of the tubes.

H fin tube is used to recover the gas waste heat of the power station boiler, the industrial boiler, the industrial kiln, the ship power plant and etc, and effectively improve the utilization rate of the fuel, and the heat exchange element is arranged at the tail of the system flue.

 

Detail

 

H-type finned tube heat exchanger elements maintain a high capacity for heat transfer, possess superior self-cleaning properties and retain the ability to effect flue gas waste heat recovery in boiler renovations. Convective heat transfer coefficient is proportional to fin pitch, but inversely proportional to fin height and fin width. Integrated heat transfer capacity is related to fin efficiency, convective heat transfer coefficient and finned ratio. Pressure drop increases with the increase of fin height and fin width. 

 

In order to improve the heat exchange efficiency and extend surface heat transfer, H-type finned tubes have been widely used in boilers and waste heat recovery in recent years. H-type finned tubes are derived largely from rectangle finned tubes. Because of their unique groove structure on the fin surface, H-type finned tubes have excellent anti-wear and anti-fouling performance.

 

Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.

 

Economizer H Type Extruded Fin Tube is available in various materials including copper and stainless steel, catering to different requirements. The low fin design ensures compactness and lightweight, making it ideal for space-constrained installations.

 

This finned tube is suitable for air coolers, radiators, and other heat exchanger applications. Its skillful manufacturing process guarantees precise dimensions and tight tolerances, ensuring seamless integration into existing systems.

Product Details

Advantages of H-finned tube:

 

The H-finned tube is the main heat exchange component in the whole exhaust gas boiler, and the H finned tube has the following advantages.

 

(1) Excellent wear resistance

 

The H finned tube heat exchanger is arranged in line, and the H fins separate the space into several small areas, which have the effect of equalizing the air flow, comparing to the smooth tube heat exchanger with the staggered arrangement and the spiral finned heat exchanger And so on, in the same other conditions, the wear life is higher 3~4 times.

 

(2) Fouling reduced

 

The formation of fouling occurred in the dorsal side and windward side of the tube. The staggered arrangement of the tube is easy to flush the tube bundle, the fouling at back side is less. It has a good self-cleaning function at the appropriate wind speed. On both sides of the H finned tube are formed straight channel, soot, it can get the best soot effect while adopting soot blower.

 

(3) Reduce the resistance of exhaust gas

 

As the H fins form straight channels on both sides, and the spiral angel of the spiral fins steer the direction of the airflow, the fins are prone to fouling and have a greater flue resistance than the H fins. Therefore, the use of H-finned tube can reduce the wind resistance, reduce the fan operation and investment costs.

 

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

 

Since the H fins have a unique zigzag structure (patented), the weld fusion rate for fins and steel pipes can be as high as 98% or more, to ensure a good heat transfer coefficient for H-finned tubes.

 

(5) Compact structure, high heat efficiency

 

The heating area per unit length is large, which of the H finned tube is 7.8 times of the smooth tube, The butt welds are all welded by argon arc welding, its welding quality is improved much higher than that of the manual welding. With the size and the weight of the equipment greatly reduced, therefore, in the same heat transfer surface, the equipment investment is greatly reduced, and larger space can be provided to the users on the aspect of the equipment installation.

 

(6) Shock-proof and noise reduced

 

Due to the device structural design and the structural characteristics of the H finned tube, it has the structural characteristics of the muffler, so the equipment can function as a muffler.

 

(7) Convenient for installation, operation and maintenance

 

While installation, it only need to connect the equipment to the exhaust gas outlet of HFO engine units, the equipment can be put into normal operation; exhaust gas boiler has check door, which can be determined the cleaning cycle according to the actual situation to ensure the heat transfer effect and increase the working life.
