Claims (4)

1. Способ контроля подачи питательной воды к проточному парогенератору, при котором температуру пара испаренной питательной воды (SW) привлекают для определения подачи питательной воды (SW), отличающийся тем, что производят совместную индикацию действительного значения (Ti) температуры пара с определенным из обусловленных эксплуатационными требованиями параметров (T1, T2, SWt, WB, L), заданным значением (Ts).1. A method of controlling the supply of feed water to a flowing steam generator, in which the vapor temperature of the vaporized feed water (SW) is used to determine the feed water supply (SW), characterized in that they produce a joint indication of the actual value (T i ) of the steam temperature with a certain operational requirements of the parameters (T 1 , T 2 , SW t , W B , L), the set value (T s ). 2. Способ по п. 1, отличающийся тем, что в качестве обусловленного эксплуатационными требованиями параметра (T1, T2, SWt, WB, L) используют мощность парогенератора (L).2. The method according to p. 1, characterized in that as the parameter determined by the operational requirements (T 1 , T 2 , SW t , W B , L), the power of the steam generator (L) is used. 3. Устройство для контроля подачи питательной воды к испарителю проточного парогенератора, отличающееся тем, что оно содержит устройство индикации (22), которое, с одной стороны, соединено с измерительным устройством (16) для определения действительного значения (Ti) температуры пара и, с другой стороны, с предусмотренным для определения заданного значения (Ts) температуры пара из обусловленных эксплуатационными требованиями параметров (T1, T2, SWt, WB, L) датчиком заданного значения (34), и предусмотренную для индикации температуры пара на выходе испарителя (6) температурную шкалу (30), причем действительное значение (Ti) и заданное значение (Ts) температуры пара могут индицироваться совместно.3. A device for controlling the supply of feed water to the evaporator of a flowing steam generator, characterized in that it contains an indication device (22), which, on the one hand, is connected to a measuring device (16) to determine the actual value (T i ) of the steam temperature, and, on the other hand, with a setpoint sensor (34) provided for determining the setpoint (T s ) of the steam temperature from the parameters determined by the operational requirements (T 1 , T 2 , SW t , W B , L), and provided for indicating the steam temperature on out e evaporator (6), temperature scale (30), wherein the actual value (T i) and a predetermined value (T s) of steam temperature can be displayed together. 4. Устройство по п. 3, отличающееся тем, что на температурную шкалу (30) наложено температурное окно (34) для заданного значения (Ts) температуры пара.4. The device according to claim 3, characterized in that a temperature window (34) is superimposed on the temperature scale (30) for the set value (T s ) of the vapor temperature.
