A gas turbine system, comprising: an exhaust gas compressor, comprising: an inlet section fluidly coupled to a turbine expander via an exhaust gas recirculation path; a detection system comprising at least one non-intrusive measurement device coupled to the inlet section, wherein the at least one non-intrusive measurement device is configured to generate a first feedback relating to droplet parameters pertaining to moisture contained within an exhaust gas flowing through the inlet section; and a controller communicatively coupled to the detection system and comprising non-transitory media programmed with one or more sets of instructions, and one or more processing devices configured to execute the one or more sets of instructions such that the controller is configured to: evaluate the first feedback for one or more indications of condensation of the moisture within the exhaust gas as the exhaust gas flows through the exhaust gas compressor; and provide a user-perceivable indication for a first corrective action to be taken if the one or more indications are indicative of moisture condensation outside of a first predetermined condensation range; or perform a second corrective action if the one or more indications are indicative of moisture condensation outside of a second predetermined condensation range; characterised in that the at least one non-intrusive measurement device comprises a water droplet size and flux measurement system. an exhaust gas compressor, comprising: an inlet section fluidly coupled to a turbine expander via an exhaust gas recirculation path; a detection system comprising at least one non-intrusive measurement device coupled to the inlet section, wherein the at least one non-intrusive measurement device is configured to generate a first feedback relating to droplet parameters pertaining to moisture contained within an exhaust gas flowing through the inlet section; and an inlet section fluidly coupled to a turbine expander via an exhaust gas recirculation path; a detection system comprising at least one non-intrusive measurement device coupled to the inlet section, wherein the at least one non-intrusive measurement device is configured to generate a first feedback relating to droplet parameters pertaining to moisture contained within an exhaust gas flowing through the inlet section; and a controller communicatively coupled to the detection system and comprising non-transitory media programmed with one or more sets of instructions, and one or more processing devices configured to execute the one or more sets of instructions such that the controller is configured to: evaluate the first feedback for one or more indications of condensation of the moisture within the exhaust gas as the exhaust gas flows through the exhaust gas compressor; and provide a user-perceivable indication for a first corrective action to be taken if the one or more indications are indicative of moisture condensation outside of a first predetermined condensation range; or perform a second corrective action if the one or more indications are indicative of moisture condensation outside of a second predetermined condensation range; characterised in that the at least one non-intrusive measurement device comprises a water droplet size and flux measurement system. evaluate the first feedback for one or more indications of condensation of the moisture within the exhaust gas as the exhaust gas flows through the exhaust gas compressor; and provide a user-perceivable indication for a first corrective action to be taken if the one or more indications are indicative of moisture condensation outside of a first predetermined condensation range; or perform a second corrective action if the one or more indications are indicative of moisture condensation outside of a second predetermined condensation range; characterised in that the at least one non-intrusive measurement device comprises a water droplet size and flux measurement system.
