Abstract (en)

[origin: EP0773348A1] The pre-heating system uses a low pressure pre-heating path (1) with heating steam connections coupled to tap-offs (A1,A2,A3) of the low pressure turbine (5). The heated condensate outlet of each low pressure pre-heater (NDV1a,NDV1b,NDV2a,NDV2b) is coupled to a drive steam collector rail (20) via a respective condensate raising device (50-53) with a feed outlet (11,13,15,17) coupled to the main condensate line downstream of the associated low pressure pre-heater.
