摘要： A steam power plant is suggested having, parallel to the low-pressure passage (VW1 to VW2), a heat reservoir (A) which is loaded with preheated condensate in weak-load times. This preheated condensate is taken from the heat reservoir (A) for generating peak-load and inserted downstream of the low-pressure preheater passage (VW1 to VW2) into the condensate line that contacts the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.

摘要： A system using hybrid Rankine cycles is provided. The system includes a first Rankine cycle system using a first working fluid, the first system producing exergy loss and residual energy from at least one of turbine extraction, turbine condensation and boiler flue gas; and a second Rankine cycle system using a second working fluid to recover the exergy loss and residual energy.
