Abstract: The invention relates to a method and to a steam power plant, wherein solar energy can be very flexibly and very efficiently coupled into the water steam circuit of the steam power plant.

Abstract: A steam power plant is suggested having, parallel to the high-pressure preheater passage (VW4 to VW6), 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 high-pressure preheater passage (VW4 to VW6) into the condensate line (19.2) resp. 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.

Abstract: 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.

Abstract: A steam power plant is suggested having, parallel to the preheater passage (VW1 to VW4), a heat reservoir (25) which is loaded with preheated condensate in weak-load times.

Abstract: The invention relates to a method for optimizing a large-scale industrial facility, especially a power plant, consisting of m subassemblies (BGj), wherein j=1(1)m) and wherein the following steps are successively carried out: comparing the parameters (KGj) of all subassemblies (BG1 to BGj) with predetermined reference values (RWj); detecting the subassemblies (Bgi) with i=1(1)m, whose parameters (KG1) are worse than the reference values (RWi) and optimizing the subassemblies (BG1) whose parameters (KGi) are worse than the reference values (RW1).
