Abstract
A circuit (10) for draining at least one combustible fluid for a cavity of a turbine includes a drain (12) in fluidic communication with the at least one cavity, and a first isolation valve (14) and a second isolation valve (16) defining between them an isolation cavity (C) of a portion of the drain. A discharge line (18) is in fluidic communication with the isolation cavity (C) to allow the discharge of air out of the isolation cavity (C). A supply line (22) supplies pressurized fluid to the isolation cavity (C), and a supply valve (24) is arranged in the supply line (22) for regulating the supply of the isolation cavity (C) with pressurized fluid. A discharge valve (20) is arranged in the discharge line (18) for regulating the discharge of the gases out of the isolation cavity (C), and a device (26) is provided for determining a failure of the drainage circuit (10).
