The wet steam exiting a low pressure steam turbine does not rapidly attain thermodynamic equilibrium because insufficient condensation nuclei are present in the phase transition zone inside the turbine. Therefore, the steam is subcooled, decreasing the power generated by the turbine, and the liquid water carried by the steam consists of relatively coarse droplets which strike the surface of the turbine blades causing erosion. Corona electrodes installed inside the turbine before the saturation line create electrically charged particles which serve as condensation nuclei, decreasing subcooling, and producing a large number of fine droplets. Thereby, thermodynamic equilibrium is more closely approached, more power is generated, and smaller water droplets cause less erosion inside the turbine.
