Generator Efficiency - an overview | ScienceDirect Topics

However, this measure can increase moisture content and thus turbine blade erosion in the last turbine stages. Increasing the average temperature at which heat is added to the power cycle by superheating causes the net work output, the heat input, and the energy efficiency to increase, while decreasing steam moisture content at the turbine exit.
