For download Steam turbine training manual pdf click the button 23-03-2016 1 Fleetingly evasive rabble is the unhap. The steam flowing from the high pressure to a lower pressure is then converted into rotating mechanical energy as the high velocity steam acts on a series of rows of blades mounted on the rotor. The importance of this method is, the turbine can maintain a constant steady speed irrespective of variation of its load. The variation in load during the operation of a steam turbine can have a significant impact on its performance. Therefore, most steam turbine CHP systems are characterized by low power to .
