Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Schnellumschaltung vom Vormischbetrieb in den Diffusionsbetrieb in Brennkammern (9, 10) einer Gasturbine bei Verlöschen der Vormischflamme bzw. bei Auftreten einer Störung, die zum Verlöschen der Vormischflamme führen kann.The invention relates to a method and Device for quick switching from premix operation in the diffusion mode in combustion chambers (9, 10) of a gas turbine when the Premix flame or if a fault occurs, the can extinguish the premix flame.

Von der Brenngaszufuhrleitung (13) zweigt vor dem Brenngasventil (1) eine Pilotgasleitung (14) ab, in die ein Pilotgasregelventil (2) eingesetzt ist.From the fuel gas supply line (13) branches before Fuel gas valve (1) from a pilot gas line (14) into which a pilot gas control valve (2) is used.

Die Brenngaszufuhrleitung (13) verzweigt sich nach dem Brenngasregelventil (1) mit Wegmessung (Z) (4) in Brennstoffzufuhrleitungen (15, 16) für beide Brennkammern (9, 10). Durch den Einbau von je einem Schnellumschaltventil (B) mit Servoventilen V1, V2 (7) in die sich verzweigenden Brennstoffzufuhrleitungen (13) wird die Brennstoffzufuhr zur Diffusionsgasleitung (15) und zur Vormischgasleitung (16) gesteuert.The fuel gas supply line (13) branches after the fuel gas control valve (1) with displacement measurement (Z) (4) in fuel supply lines (15, 16) for both combustion chambers (9, 10). By installing one quick changeover valve (B) with servo valves V 1 , V 2 (7) in the branching fuel supply lines (13), the fuel supply to the diffusion gas line (15) and the premix gas line (16) is controlled.

Die Überwachung der Brennkammern (9, 10) erfolgt im Bereich des Flammrohres (17) durch Druckmessgeräte P1, P2 (5) und durch optische Flammüberwachungen B1, B2 (6).The combustion chambers (9, 10) are monitored in the area of the flame tube (17) by pressure measuring devices P 1 , P 2 (5) and by optical flame monitors B 1 , B 2 (6).

Der Wegaufnehmer (Z) (4), die Überwachungsgeräte P1, P2 (5), B1, B2 (6) und die Servoventile (V1, V2 (7) der Schnellumschaltventile (3) sind mit einer Ansteuerlogik für Schnellumschaltung (8) verdrahtet.
