Industial boiler part heat exchanger H finned tube economizer is a
kind of boiler parts.Square or Rectangular H Fins are welded on a
steel base tube. Having two steel circular symmetry to be welded on
fluorescent tubes to form ins positive shape much like letter "H",
so we called H-fin tube. H finned tube widely used in utility
boilers, industrial boilers, marine power, such as the tail of heat
exchanger components.
Characteristics of H Fin Tube
Add the heat exchange area and reduce the number of tubes, reduce
the fume speed and abrasion.
Can be made to double H type fin tube, high rigidness to fit long
tube row.
Arranged in line to make the space into many small zones, averaged
air flow to reduce the abrasion.
With straight channel to gain the best ash-blowing effect.
Compact structure to reduce the weight and reduce the manufacturing
cost.
