Rectangular Single or Twin Finned Tubes for economizer

H/HH-Type Finned Tube：

The H-type Fin Tube is to weld two steel sheets with an arc in the middle symmetrically with the light pipe to form a fin (rib or disc). The front shape is quite similar to the letter "H", which is an efficient expansion. Heating surface energy-saving products.
The H-type finned tube has the advantages of high welding seam fusion rate, high welding tensile strength, small contact thermal resistance, good heat transfer, and strong expansion ability. 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 finned tubes and spiral finned tubes, H-shaped finned tubes can maximize the expansion of the heating surface.
Under the same degree of heat exchange effect, H-type fin tube economizer can greatly save space and volume. In addition to H-type economizer, it can also be assembled into H-type evaporator, H-type superheater, H-type air heater and many other products. H-type finned tube has been included in the "China High-tech Product Catalog".
Structural form: The basic form is single "H" type and double "H" type.
Our company can design and manufacture safe, reliable and efficient H-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 dust accumulation, small wear 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 and chemical waste heat recovery.
Third Part Inspection is acceptable.

Advantages of HH / H finned tube

1) The H-type finned tube economizer instead of the smooth tube economizer can increase the heat exchange area, reduce the number of tubes, increase the flue gas flow section, reduce the flue gas velocity and wear.
2) The H-type finned tube can be made into a "double H" type finned tube with double tubes, which has good structural rigidity and can be used in the case of long tube banks.
3) The H-type finned tube economizer is arranged in sequence. The H-type finned tube divides the space into several small areas, which has the function of flow equalizing and greatly reduces the wear
4) The best soot blowing effect can be obtained by forming a straight channel on both sides of H-shaped fins.
5) The space is compact, the overall weight is greatly reduced, and the cost is reduced
6) Energy saving and low power consumption: the economizer used for the generator unit can reduce the heat loss of exhaust gas of the generator by at least two thirds, and only consume 2-4kw per ton of steam
7) Simple operation and maintenance; labor saving: the economizer is assembled as a whole, with fewer moving parts, simple structure and easy installation. High level of automation, simple operation and maintenance, can reduce the number of operators.
