<P>PROBLEM TO BE SOLVED: To provide a method for increasing the operational flexibility of a steam turbine during a shutdown phase. <P>SOLUTION: The method 400 for improving the operational flexibility of a turbomachine during the shut down phase is provided. The turbomachine may include a first section, a second section, and a rotor disposed within the first section and second sections. The method 400 may determine an allowable range of a physical parameter associated with the first section and/or the second section. The method 400 may modulate a first valve and/or a second valve to allow steam flow into the first section and the second section respectively, wherein the modulation is based on the allowable range of the physical parameter. In addition, the physical parameter allows the method 400 to independently apportion steam flow between the first section and the second section of the turbomachine, during the shutdown phase. <P>COPYRIGHT: (C)2012,JPO&INPIT |
