The problem is associated with high-velocity and turbulences created by the presence of the welding penetration as a flow obstacle. […]

[vc_row][vc_column][vc_custom_heading text=\”Heat Transition Zone\” use_theme_fonts=\”yes\”][vc_custom_heading text=\”Introduction\” font_container=\”tag:h3|text_align:left\” use_theme_fonts=\”yes\”][vc_column_text] As superheated steam enters in the transition zone of the turbine and expands into LP section, steam may cross the saturation line, in the Mollier diagram, to eventually form nucleation of moisture drops on blades and disk surfaces. Consequently, a number of physical-chemical processes will lead to
