Title (EN) DEVICE AND METHOD OF SCAVENGING LIQUID FUEL FOR A MULTIFUEL GAS TURBINE
(FR) DISPOSITIF ET PROCEDE DE BALAYAGE DU CARBURANT LIQUIDE POUR UNE TURBINE A GAZ MULTI-COMBUSTIBLES
Abstract: front page image
(EN)The invention relates to a turbine 1 including at least one combustion chamber 2 and a scavenging device, the combustion chamber capable of being supplied with liquid fuel through a first circuit 5 comprising a non-return valve 9, the scavenging device including: a scavenging gas-providing means 6 and a scavenging gas-supplying second circuit 7 that is connected to the first circuit, downstream from the non-return valve. The turbine 1 includes a compensation means 12 comprising at least two inputs, one of the inputs being coupled with the first circuit 5, upstream from the non-return valve, and the other input being coupled with the second circuit 7, downstream from the non-return valve, the compensation means being capable of reducing the pressure difference between the scavenging gas downstream from the non-return valve and the liquid fuel upstream from the non-return valve while maintaining the valve in a closed position.
(FR)L'invention concerne une turbine (1) comprenant au moins une chambre de combustion (2) et un dispositif de balayage, la chambre de combustion pouvant être alimentée en carburant liquide par un premier circuit (5) comportant un clapet anti-retour (9), et le dispositif de balayage comprenant : un moyen de fourniture (6) d'un gaz de balayage, et un deuxième circuit (7) pour l'alimentation en gaz de balayage, relié au premier circuit, en aval du clapet anti-retour. La turbine (1) comprend un moyen de compensation (12) comportant au moins deux entrées, l'une des entrées étant raccordée au premier circuit (5), en amont du clapet anti-retour, et l'autre entrée étant raccordée au deuxième circuit (7), en aval du clapet anti-retour, le moyen de compensation étant capable de réduire la différence de pression entre le gaz de balayage en aval du clapet anti-retour et le carburant liquide en amont du clapet anti-retour, en maintenant le clapet en position fermée.
