Abstract

A method for producing a heat exchange unit (22) for a recovery steam generator (20) comprising a tube bundle (24) each tube of which is equipped with segmented finning (26) jutting radially from said tubes (24), said segmented finning (26) being obtained by winding in a spiral and welding a metallic strip having a substantially trapezium-shaped cross section around said tubes (24), on said metallic strip a series of transversal cuts being made, which have a predetermined pitch and extend from a side edge of the strip, corresponding to the shorter base of the trapezium, for a predetermined depth, said strip being welded to said tubes (24) along the opposite side edge, corresponding to the longer base of the trapezium.
