Abstract

Single-pass forced circulation steam generator system, with a steam-driven turbine and a condenser, as well as a system of pipes that avoid the turbine, especially when starting, characterized in that means, known per se, are provided for the circulation of the working medium which, for taking the working medium, is connected in the part of the steam generator downstream of the transformation zone and for the return of the working medium in the part of the steam generator upstream of the transformation zone, because the piping system used for starting shows, behind a relaxation device, already known per se, a separation organ that separates the working medium into water and steam, because there is also a connection for water from the separation organ to the condenser part and because finally there are other connection pipes for steam, which come out of the separation organ and are connected cited with a device for deaeration of the working medium, with at least one device for the pre-heating of the feed water and with the condenser part, this piping system being designed for a maximum of 30%, especially for a maximum of 10%, of the quantity of working medium at full load of the steam generator with forced circulation and single passage.
