Embodiment Construction
[0031] The FIGURE shows a claimed steam power plant 1, having a steam turbine 3 coupled to a generator 21 and a fired steam generator 5.
[0032] The steam turbine 3 has three stages, a first turbine stage 11, a second turbine stage 13 and a third turbine stage 15, which are configured as a high-pressure stage, a medium-pressure stage and a low-pressure stage.
[0033] In the present exemplary embodiment in the FIGURE the steam generator 5 is a boiler fired by coal 27, to which combustion air 29 is supplied to maintain the coal-firing process.
[0034] A heating surface 37 is disposed in the area of the hot end of the steam generator 5 and an intermediate superheating heating surface 35 is disposed in a lower temperature area.
[0035] The heating surface 37 serves to heat a water supply 24 from a water supply tank 23 in the steam generator 5 such that operating steam can be supplied to the first turbine stage 11.
[0036] After partial expansion in the first turbine stage 1 the steam is subj...
