| Abstract: | This paper mainly discusses the off-design traits for the last stage of condensed steam turbine.For example, the regular change of reaction degree, the loss of exhausted velocity , the change characteristics of the pressure exerted on the last stage . This kind of analysis will be helpful for us to have a overall understanding of the steamed turbine work and will play an important part in a analysis of efficiency. |
