Description
trittsleitung 15 vom Niederdruckteil 9 der Verdichtergruppe 7 geöffnet bleibt Die Ausblasventile 25 und 26, sowie die Bypassventile 27,28, welche als Dreiwegeventile ausgebildet sind, werden so gestellt, ditß sowohl der Mitteldruckteil 9, als auch der Hochdruckteil 10 des Verdichterteiles 7 Luft aus der Atmosphäre ansaugen kann und durch die genannten Ventile 25,26, wieder in die Atmosphäre ausblasen könnea Dadurch entsteht im Mittel- und Hochdruckteil des Verdichterteiles 7 nur ein geringer Widerstand und es kann eine Antriebsmaschine mit kleiner Leistung verwendet werden. Nach dem Einschalten des Anwurfmotors 11 fördert der Niederdruckteil 8 der Verdichtergruppe 7 Luft über die Austrittsleitung 15 direkt in die Niederdruckbrennkammer 5 des Niederdruckteiles 4 der Gasturbine 1. Nach Erreichen der Zünddrehzahl des Niederdruckteiles 4 wird die Niederdruckbrennkammer 5 gezündet und die Anlage auf die Nenndrehzahl und die Netzfrequenz hochgefahren. Um eine Rückströmung in den Hochdi uckteil 2 der Gasturbine 1 zu verhindern, wodurch eine Überhitzung dieses Teiles erfolgen könnte, können, das Absperrventil 35 und das Absperrorgan 30 geöffnet, jedoch muß das Absperrorgan 31 zum Luftspeicher 19 dann geschlossen werden. Vorzugsweise werden das Absperrventil 35 und das Absperrorgan 30 jedoch nur soweit geöffnet, daß ein reduzierter Anschluß zum Hochdruckteil 2 erfolgt, wodurch dieser gespült wird und Wärmestauungen vermieden werden. Sobald die volle Nenndrehzahl und damit die Netzfrequenz des Motor-Generators 14 erreicht ist, wird der Motor-Generator 14 über die Anschlüsse 37 an das Netz geschaltet und wirkt nun als Antriebsmotor. Die Niederdruckbrennkammer 5 wird gelöscht und das Absperrventil 35 geschlossen, während das Absperrorgan 31 geöffnet und am Ausblasventil 24 der Luftdurchfluß zum Zwischenkühler 23 ganz freigegeben wird. Das Ventil 36 in der Austrittsleitung 15 wird ebenfalls geschlossen und die Gasturbine 1 über die Kupplung 13 vom Motor-Generator 14 getrennt Nunmehr fördert der Niederdruckteil 8 der Verdichtergruppe 7 über die Austrittsleitung 15, die Leitung 21, den Kühler 23, die Rückschlagklappe 32 und die Zuführungsleitung 18 direkt in den Luftspeicher 19.inlet line 15 from the low-pressure part 9 of the compressor group 7 remains open The exhaust valves 25 and 26, and the bypass valves 27, 28, which are designed as three-way valves are designed so that both the Medium-pressure part 9 and the high-pressure part 10 of the compressor part 7 suck in air from the atmosphere can and can blow out again into the atmosphere through the valves 25, 26 Middle and high pressure part of the compressor part 7 only a low resistance and it can be a prime mover can be used with small power. After the starter motor 11 has been switched on, the low-pressure part delivers 8 of the compressor group 7 air via the outlet line 15 directly into the low-pressure combustion chamber 5 of the low-pressure part 4 of the gas turbine 1. After reaching the ignition speed of the low-pressure part 4, the The low-pressure combustion chamber 5 is ignited and the system is run up to the nominal speed and the mains frequency. In order to prevent a backflow into the high pressure part 2 of the gas turbine 1, as a result of which overheating this part could be done, the shut-off valve 35 and the shut-off element 30 open, but the shut-off element 31 to the air reservoir 19 must then be closed will. Preferably, however, the shut-off valve 35 and the shut-off element 30 are only opened to the extent that there is a reduced connection to the high-pressure part 2, whereby it is flushed and heat build-up is avoided will. As soon as the full rated speed and thus the line frequency of the motor generator 14 is reached is, the motor generator 14 is connected to the network via the connections 37 and now acts as a drive motor. The low-pressure combustion chamber 5 is extinguished and the shut-off valve 35 is closed while the shut-off element 31 is opened and the air flow to the intercooler 23 is completely released at the blow-off valve 24 will. The valve 36 in the outlet line 15 is also closed and the gas turbine 1 via the coupling 13 separated from the motor-generator 14 The low-pressure part 8 of the compressor group 7 now delivers Via the outlet line 15, the line 21, the cooler 23, the non-return valve 32 and the supply line 18 directly into the air reservoir 19.
Nach Erreichen eines entsprechenden Ladezustandes des Luftspeichers 19 wird beim Ausblasventil 25 und beim Bypassventil 27 die Freigabe zur Atmosphäre geschlossen und zu den Leitungen 16 und 21 und zur Rückschlagklappe 32,33 geöffnet und die weitere Aufladung des Luftspeichers 19 vom Niederdruckteil 3 und dem Mitteldruckteil 9 gemeinsam weitergeführt Bei weiterem Druckanstieg im Luftspeicher 19, welcher das Hinzuschalten des Hochdruckteiles 10 des Verdichterteiles 7 erforderlich macht, wird durch eine Umstellung des Ausblasventil 26 und des Bypassventiles 2h analog zu der vorher beschriebenen des Mitteldruckteiles 9, der Hochdruckteil 10 zur Aufladung des Luftspeichers 19 herangezogen. Nunmehr erfolgt im letzten Teil des Füllvorganges der Luftdurchfluß zum Luftspeicher noch zusätzlich über die Austrittsleitung 17, die Rückschlagklappe 34 und die Zuführungsleitung 18.After a corresponding state of charge of the air reservoir 19 has been reached, the blowout valve 25 and the bypass valve 27 closes the release to the atmosphere and to lines 16 and 21 and to the non-return valve 32,33 opened and the further charging of the air accumulator 19 from the low-pressure part 3 and the Medium-pressure part 9 continued together of the high-pressure part 10 of the compressor part 7 is required, is achieved by converting the Blow-out valve 26 and the bypass valve 2h analogous to the previously described medium-pressure part 9, the high-pressure part 10 for charging the air reservoir 19 used. Now, in the last part of the filling process, the air flow to the air reservoir also takes place Via the outlet line 17, the non-return valve 34 and the supply line 18.
Falls der Luftspeicher 19 aus irgendwelchen Gründen, beispielsweise eine Revision, nicht zur Verfügung steht, könnte die Anlage als normale Gasturbinenanlage betrieben werden, d. h. daß nach Zuschaltung des Motor-Generators 14 an das Netz die Hochdruckbrennkammer 3 gezündet wird und die Ausblasventile 25, 26 und die Bypassventile 27, 28 des Verdichterteiles 7 so gestellt werden, daß auch der Mitteldruckteil 9 und der Hochdruckteil 10 des Verdichterteiles Luft in die Gasturbine 1 fördern. Hierfür muß das Ventil 36 geschlossen werden und die Kupplungen 13 zwischen der Gasturbine 1 und dem Motor-Generator 14, sowie zwischen dem Motor-Generator 14 und dem Verdichterteil 7 bleiben eingekuppeltIf the air reservoir 19 is not available for any reason, for example a revision, the plant could be operated as a normal gas turbine plant, i. H. that after switching on the motor-generator 14 to the network, the high-pressure combustion chamber 3 is ignited and the exhaust valves 25, 26 and the bypass valves 27, 28 of the compressor part 7 are set so that the medium pressure part 9 and the High-pressure part 10 of the compressor part convey air into the gas turbine 1. For this, the valve 36 must be closed are and the clutches 13 between the gas turbine 1 and the motor generator 14, as well as between the Motor generator 14 and the compressor part 7 remain coupled
