Title
(EN) CIRCUIT FOR DRAINING A COMBUSTION CHAMBER AND METHOD FOR DETERMINING THE FAILURE OF SUCH A CIRCUIT
(FR) CIRCUIT DE DRAINAGE D'UNE CHAMBRE DE COMBUSTION ET PROCEDE DE DETERMINATION DE DEFAILLANCE D'UN TEL CIRCUIT
Abstract
(EN)
What is proposed is a circuit (10) for draining at least one combustible fluid for a cavity of a turbine, comprising: - a drain (12) in fluidic communication with said at least one cavity, - a first (14) and a second (16) isolation valve defining between them an isolation cavity (C) of a portion of the drain, - a discharge line (18) in fluidic communication with the isolation cavity (C) to allow the discharge of air out of the isolation cavity (C), - a supply line (22) for supplying pressurized fluid to the isolation cavity (C), - a supply valve (24) arranged in the supply line (22) for regulating the supply of the isolation cavity (C) with pressurized fluid, - a discharge valve (20) arranged in the discharge line (18) for regulating the discharge of the gases out of the isolation cavity (C), and - a device (26) for determining a failure of the drainage circuit (10).
