Abstract (en)
A feed water system for feeding water from a condenser to a steam generator in a steam turbine plant. The feed water system has a feed water/condensate water pump (2) for pumping up water from a condenser; a control valve (4) disposed downstream of the feed water/condensate water pump; a heating line (8) disposed downstream of the control valve, the heating line including a heat exchanger (12) for heating water; a bypass line for bypassing the heating line downstream of the control valve: and inlet and outlet bypass (6, 14) valves for water selectively flowing through either the heating line or the bypass line. The inlet and/or outlet bypass valves are activated by pistons (28, 30) which are driven by water pressure. A valve-activation line (48) for providing water pressure to the pistons is branched from a point between the feed water/condensate water pump and the control valve. <IMAGE>
