| Abstract: | For 1 000 MW unit small steam turbine without a separate condenser,it elaborates the influence on unit start-up and normal operation.Analysis and evidence is made concerning unit safety and economics through comparison of different configuration,and comes to the conclusion that the tightness of exhaust valve is so important if small steam turbine has no separate condenser.And method to check the tightness,the measures to guarantee the tightness of exhaust steam isolation valve is proposed. |
