Mass production of high performance of large heat transfer area of spiral finned tube
Spiral finned 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.
Description of H-fin boiler tubes: Spiral finned tube is a spiral fin high efficiency heat transfer element. Its heat transfer area for light pipe several times or more, can strengthen heat transfer, reduce the flow resistance, reduce the metal consumption, thus improves the efficiency of heat exchange equipment and operation reliability. At present, the spiral finned tube has been widely used in all kinds of boiler. Spiral finned tube can be manufactured a variety of methods, at present, used in boilers, pressure vessels and other finned tube heat exchange equipment has the following several kinds of methods: high-frequency resistance welding of spiral finned tube, brazing spiral finned tube and spiral finned tube as a whole. Spiral finned tube was introduced in detail the manufacturing methods, performance evaluation, application and the advantages of integral type spiral finned tube, etc
Advantages of Spiral 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.

Kaineng Factory Area
Description of Spiral Finned Tubes: The spiral fin steel pipes currently used are mostly wound, high frequency welded and brazed spiral fin steel pipes.
The advantages of spiral fin steel pipes are as follows: 1. Long service life, is more than 20 years; 2. The surface of the fin is smooth, and it is not easy to produce ash accumulation, ash blocking and slagging. 3. It has good density, yield strength, tensile strength and wear resistance of metal structure. 4. The welding quality is high, so that it is not easy to cause unstable heat transfer performance because of fin loosening and falling off.
