H type finned tubes for boiler economizer

The structure of H type finned tube is mainly to weld two steel sheets with arc in the middle symmetrically with light tube to form fins (ribs). Its front shape is quite like the letter "H", so it is called H type finned tube. The two fins of the fin are rectangular, approximately square, and its side length is about 2 times the diameter of the light tube, which belongs to the extended heating surface.

H type finned tube can also be made into double tube "double H" type finned tube, which has good structural rigidity and is suitable for occasions with long tube rows.

H type finned tube is to weld two steel sheets with arc in the middle symmetrically with light tube to form fins (ribs or discs). The front shape is quite like the letter "H", which is an energy-saving product with extended heating surface.

H-type fin tube has good heat transfer characteristics, low flue gas flow resistance, good anti-fly ash wear performance, and can effectively reduce ash accumulation, thereby greatly extending the service life of H-type fin economizer

H-type fin tube has high weld fusion rate, high welding tensile strength, low contact thermal resistance, good heat transfer, strong expansion capacity and other advantages. The H-type economizer assembled with it has the characteristics of high heat exchange efficiency, low resistance, low wear and light weight. Compared with traditional fin tubes and spiral fin tubes, H-type fin tubes can greatly expand the heating surface.

Under the same degree of heat exchange effect, H-type fin tube economizer can greatly save space volume. In addition to H-type economizer, it can also be assembled into H-type evaporator, H-type superheater, H-type heater and many other products. .

Structural form: The basic form is single "H" type and double "H" type.

Datang factory can design and manufacture safe, reliable and efficient H-type finned tubes according to customer needs and the actual situation of power plant transformation. The company has a complete and independent product quality assurance system. The H-type finned tubes produced have the characteristics of high heat transfer efficiency, low flue gas resistance, light ash accumulation, low wear and tear, and small space occupation.

H-type finned tubes can be widely used in heat exchange components such as power station boilers, industrial boilers, ship power, metallurgical chemical waste heat recovery.

1. Larger heat transfer area: The unique "H"-shaped fin structure of the H-type finned tube can provide a larger heat transfer area in a limited space, making heat transfer more efficient, thereby improving heat transfer efficiency.

2. Excellent heat transfer performance: The gap between the fins and the tube wall of the H-type finned tube is tighter, which increases the heat transfer contact area between the fluid and the fins and improves the heat transfer performance. At the same time, the shape of the fins also helps to improve the heat transfer coefficient and speed up the heat transfer rate.

3. High strength and pressure resistance: H-type finned tubes are made of high-quality materials, have high strength and pressure resistance, can operate stably under high pressure and high temperature conditions, and are suitable for heat exchange applications in various industrial fields.

4. Strong corrosion resistance: H-type finned tubes can use different materials for different working media, so they have strong corrosion resistance and can adapt to the heat transfer requirements of various chemical media, increasing their application range in chemical, petroleum and pharmaceutical industries.

5. Anti-ash accumulation and self-cleaning function: The flue gas flow of H-type finned tubes is parallel to the fins, and has good anti-ash accumulation and anti-wear performance. It has good self-cleaning function and is suitable for occasions with high smoke concentration.

6. Compact structural design: The compact structural design of H-type finned tubes enables it to provide a large heat transfer area in a relatively small space, which is very beneficial for environments with limited space and can save engineering costs and installation space.
