STEAM POWER PLANT

摘要

The invention relates to a steam power plant (1) in which a working fluid (2) circulates in a circuit, wherein a regenerative intermediate superheater (30) is provided which preferably intermediately superheats the entire flow of the working fluid (2) before it enters into a low-pressure turbine (11) and which is heated by means of steam extractions from the relief path (8) situated upstream. The steam flows which heat the intermediate superheater (30) are preferably utilized for feed fluid pre-heating (4). The intermediate superheater (30) is embodied as multi-stage regenerative intermediate superheater (30). This leads to increased efficiencies and reduced erosion on the low-pressure blades.
