Abstract (en)
A steam power plant is described including on a single rotor (17) at least one high pressure turbine (14) or turbine section having a steam exit connected in operation to a first steam reheater (151) and at least two intermediate pressure turbines (161, 162) or turbine sections with a first (161) of the at least two intermediate pressure turbines or turbine sections having a steam exit connected in operation to a second steam reheater (152) and with a second (162) of the at least two intermediate pressure turbines or turbine sections having a steam entry to receive steam from the second steam reheater (152) and a steam exit connected to one or more low pressure turbines (163) or turbine sections, whereby the at least two intermediate pressure turbines (161, 162) or turbine sections are each separated into a high temperature turbine (161-1, 162-1) or turbine section and into a low temperature turbine (161-2, 162-2) or turbine section.
