| 摘要 |
The invention relates to a method for the separation of residual gases and working fluid in a combined cycle water/steam process, which provides for the multi-stage compression and multi-stage expansion of the mixture of working fluid and reaction products from the additional liquid and/or gaseous fuels, by the use of steam. The aim of the invention is the minimisation of the working fluid losses and minimisation of the additional necessary energy use. Said aim is achieved, whereby the expanded exhaust gas from the high pressure turbine stage ( 19 ) is subjected to a cooling process which cools the same to the condensation temperature of the steam contained in the exhaust gas ( 6 ). The non-condensed parts of the exhaust gas ( 6 ) are bled off, whereby the condensation of the working fluid, the bleeding off of non-condensed residual gases ( 25 ), the depressurisation of the working fluid condensate and the evaporation of the condensed working fluid are carried out in a residual gas separator ( 10 ).
