Description
Es ist bekannt, Dampfturbinen während des Stillstandes dadurch zu heizen, daß man sie von einem dampf- oder gasförmigen Wärmeträger durchströmen läßt. Dies hat aber nur dann Erfolg, wenn der Temperaturverlauf gleichmäßig vor sich geht, also vor allem in der Umfangsrichtung keine Temperaturunterschiede auftreten. Hat die erste Stufe der Turbine nur teilweise Beaufschlagung oder ist beim Stillstand der Turbine nur ein Teil der Regelventile offen, so hat die Einführung des Wärmeträgers durch die Düsen der ersten Stufe eine ungleichmäßige Temperaturverteilung und dadurch ein Verziehen des Läufers zur Folge.It is known to heat steam turbines during standstill by having them from allows a steam or gaseous heat transfer medium to flow through. But this is only successful when the temperature profile is uniform, i.e. especially in the circumferential direction no temperature differences occur. Has the first stage of the turbine only partially If the turbine is acted upon or if only some of the control valves are open when the turbine is at a standstill, then the introduction of the heat carrier through the nozzles of the first stage an uneven Temperature distribution and thus a warping of the rotor as a consequence.
Zur Behebung dieses Nachteils wird gemäß der Erfindung vorgeschlagen, einen konzentrisch zur Welle gelegenen, ringförmigen, mit gleichmäßig verteilten Austrittsöffnungen versehenen besonderen Zuführungskanal für den Wärmeträger ao anzuordnen.To overcome this disadvantage is proposed according to the invention, a concentric to Shaft located, ring-shaped, provided with evenly distributed outlet openings special To arrange the supply channel for the heat carrier ao.
Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht. Hierin bezeichnet α eine mehrstufige Dampfturbine, welche eine beliebige Anzahl von Düsenkammern b besitzt. Konzentrisch zur Welle ist ein besonderer Ringkanal c angeordnet, der mit einer Anzahl auf seinen Umfang gleichmäßig verteilter Austrittsöffnungen d versehen ist, so daß eine gleichmäßige Verteilung des Wärmeträgers auf das Turbineninnere erfolgt.The subject matter of the invention is illustrated in the drawing in an exemplary embodiment. Here, α denotes a multi-stage steam turbine which has any number of nozzle chambers b . A special annular channel c is arranged concentrically to the shaft, which is provided with a number of outlet openings d uniformly distributed over its circumference, so that the heat carrier is evenly distributed over the interior of the turbine.
Ist es unerwünscht, den Abdampfstutzen ebenfalls zu erwärmen, so kann der Übertritt des Wärmeträgers in den Abdampfstutzen durch eine Absperrvorrichtung e verhindert werden. In diesem Falle ist es zweckmäßig, hinter dem letzten Rad einen ringförmigen Abführkanal f vorzusehen, der ebenfalls zwecks gleichmäßiger Abführung des Wärmeträgers mit einer Anzahl auf den ganzen Umfang des Kanals verteilter Eintrittsöffnungen g versehen ist.If it is undesirable to also heat the exhaust steam connector, the transfer of the heat transfer medium into the exhaust steam connector can be prevented by a shut-off device e . In this case, it is useful to provide an annular discharge channel f behind the last wheel, which is also provided with a number of inlet openings g distributed over the entire circumference of the channel for the purpose of uniform discharge of the heat carrier.
