| Abstract: | Reasons for the lowered pressure differences between the HP side and LP side of the double back pressure condenser of a 600 MW super-critical generating unit are analyzed in this paper. With a view to taking the technical advantages of the double back pressure condenser, the air extraction system in the condenser is upgraded. Comparative tests on the air extraction system in the different operation modes before and after the upgrading prove that the upgrading on the connection of the air extraction system o... |
