Recently Xuzhou Power Plant carried out the updating-retrofitting of No.4 125 MW steam turbine-generator set during overhaul including updating of generator retrofitting of flow passages of steam turbine adopting DCS and DEH to adopt Japans Mitsubishi reaction type controlled vortex technology in the retrofitting of flow passage part of steam turbine with the safety and economics of steam turbine greatly improved. This article introduces the retrofitting process the economics of retrofitted steam turbine and finally puts forward the views and proposals for further improving the economics of 125 MW unit.
