Abstract

Ein Separator (8) ist nach dem Überhitzerabschnitt (4) des Zwangdurchlauf-Abhitzekessels (1) angeordnet. Von einer Austrittsleitung (5), die vom Überhitzerabschnitt (4) zur Dampfturbine (6) verläuft, ist eine Abzweigleitung (9) abgezweigt, die zum Separator (8) verläuft. Vom Separator (8) verläuft eine Ausströmleitung (11) für abgeschiedenes Wasser zum Zwangdurchlauf-Abhitzekessel (1). Der im Separator (8) abgeschiedene Dampf kann durch eine Bypassleitung (13) zum Kondensator/Hotwell (14) strömen. Zum Anfahren des Zwangdurchlauf-Abhitzekessels (1) wird dieser mit Wasser gefüllt, das Wasser durch den Separator (8) und die Ausströmleitung (11) im Zwangdurchlauf-Abhitzekessel (1) bzw. Wasser-/Dampf-Kreislauf kreislaufgeführt und die Wärmezufuhr eingeleitet. Das Hauptabsperrorgan (7) vor der Dampfturbine (6) ist dabei geschlossen, das Abzweigabsperrorgan (10) in der Abzweigleitung (9) vor dem Separator (8) ist offen. Bei einsetzender Bildung von Dampf strömt dieser aus dem Separator (8) durch die Bypassleitung (13) zum Kondensator (14). Entspricht der Dampf den Anforderungen der Dampfturbine (6), werden das Hauptabsperrorgan (7) geöffnet und das Abzweigabsperrorgan (10) geschlossen, womit ein frühzeitiges Anfahren der Dampfturbine (6) sichergestellt ist.

Figure 00000001
A separator (8) is arranged after the superheater section (4) of the once-through waste heat boiler (1). A branch line (9), which runs to the separator (8), is branched off from an outlet line (5) which runs from the superheater section (4) to the steam turbine (6). An outflow line (11) for separated water runs from the separator (8) to the once-through waste heat boiler (1). The steam separated in the separator (8) can flow through a bypass line (13) to the condenser / hotwell (14). To start up the once-through waste heat boiler (1), it is filled with water, the water is circulated through the separator (8) and the outflow line (11) in the once-through waste heat boiler (1) or water / steam circuit and the heat supply is initiated. The main shut-off device (7) in front of the steam turbine (6) is closed, the branch shut-off device (10) in the branch line (9) in front of the separator (8) is open. When steam begins to form, it flows from the separator (8) through the bypass line (13) to the condenser (14). If the steam meets the requirements of the steam turbine (6), the main shut-off device (7) is opened and the branch shut-off device (10) is closed, thus ensuring that the steam turbine (6) starts up early.
