H/HH FIN TUBE
H/Hh Fin Tube is also know as square Fin Tube or Rectangular Fin Tube, has single tube type(H type fin tube) or double tube type(HH or double H type fin tube), is widely used as enhanced heat exchange element for power plant boilers, industrial boilers, furnaces, marine boilers and economizers in flue gas waste heat recovery systems.
WHY USE FINNED TUBES
Rigid structure and higher wear life
The fin tubes are assembled in rows, the heating area is divided into several individual small area by aligned fins, provide a current sharing effect on the flue gas. comparing to the staggered spiral Finned Tube bundles, the arrangement has more rigid structure and higher wear life
Lower flue side resistance, compact assembly, shorter breeching duct and lighter of equipment weight
Due to its own shape properties, H/HH Fin Tube has excellent wear resistance and self-cleaning function, which can effectively reduce the flue gas side resistance. The tube bundles could be arranged more compactly, and the overall boiler cost is reduced.
H/HH fin tube has better performance on anti-ashing and wear resistance than spiral finned tube
Lower thermal contact resistance and higher thermal conductivity
Up to 98% weld fusion rate helps the H/HH fin tube having lower thermal contact resistance and higher thermal conductivity. Although the heat convection is weakened by no air turbulence, the ash is less accumulated on the heat transfer surface during operation due to forwarding flow characteristics through the heat transfer tube bundles, additionally the fins are more uniformly flushed. Furthermore, the effective utilization rate of the extended surface of the H-type fin is higher than that of the spiral finned tube, and the overall heat transfer efficiency is increased by about 10% compared with the spiral finned tube bundle.
