H fins pipe (square finned tube)

Square finned tube also called H fins is made for recovery of power station boiler, industry boiler, industrial furnace, ship power equipment, which can effectively improve the utilization rate of fuel and arrange the strong heat transfer components in the tail flue of the system.

Due to the low temperature flue gas convection heat transfer - that is, the characteristics of flue gas on the tube wall of exothermic coefficient a1 is much smaller than soda side wall is exothermic coefficient a2, it is necessary to adopt extended heating surface in the flue gas side. Nowadays what used on the boiler is economizer ( also called a economizer), which has the types as follows: a light tube, screw up plate, cast iron finned tube type, the membrane wall tube type, etc. In addition to the light tube, the rest are extended surface structure. 
In the structure design, Fins pipe adopted a separate structure for the easy to knot of pipe gray parts, which overcomes problem that the spiral tube easy to dust, ash, and the defect of gas resistance, and which is the improved product of spiral finned tube.
