Abstract
The invention relates to a method of detecting the presence of a liquid fuel leak in a gas turbine (1). During this method: a reference value (27, 37) is determined for at least a first operating parameter of the turbine, a value (29, 39) of the said operating parameter is measured during a start-up phase of the turbine, the measurement value and the reference value are compared, whether a first anomaly (13, 41) is present is identified, an alert notification (33, 43) is generated if a first anomaly (31, 41) is detected for the first parameter, and in parallel shutdown of the turbine (35, 45) is triggered if a second anomaly (34, 44) is detected for a second parameter. The invention also relates to a device for detecting a liquid fuel leak in a gas turbine, employing such a method.
