摘要： A flow control system is provided. The flow control system includes at least one control valve coupled to at least one nozzle of a turbine engine, wherein the control valve is configured to regulate fluid flow in a first direction or a second direction. The first direction is when the fluid is channeled from a compressor to the nozzle and the second direction is when the fluid is channeled from the nozzle to an exhaust section of the turbine engine. A controller is coupled to the control valve and is configured to control the fluid flow in the first direction during operation of the turbine engine and to change the direction of the fluid flow from the first direction to the second direction to facilitate reconditioning of the turbine engine.
