| Abstract: | The concept of relative internal efficiency of steam turbine is discussed firstly. Then based the basic principle of steam turbine, this paper gives the mathematics models that can be used to calculate the effect of the relative internal efficiency of cylinders on efficiency of steam turbine. The models provide efficient means for diagnosis of thermal economy and prediction benefit of improving steam path of steam turbine. |
