METHOD FOR GENERATING STEAM AND STEAM GENERATION DEVICE

The invention relates to a method for generating steam using condensate (4) returned in the form of feed water (11). So that higher efficiency can be achieved, the invention proposes that the feed water (11) is evaporated in a steam generator (17) with the formation of process steam (3), the process steam (3) is at least partially condensed in a consumer device (V) with the dissipation of heat and formation of a condensate (4), the condensate (4) is at least partially supplied to a feed water treatment apparatus (7) for treatment, the feed water (11) treated in the feed water treatment apparatus (7) is separated in a flash tank (12) into a steam phase (13) and a liquid phase (14), the liquid phase (14) of the feed water (11) is supplied to the steam generator (17) and in the steam generator (17) is evaporated with the formation of process steam (18) and the steam phase (13) of the feed water (11) is supplied to a compressor (15) for compressing and forming a process steam (19).
