Abstract
A method of flushing liquid fuel from valves and nozzles in a gas turbine is conducted via a mixing valve including flow passages for fuel and water. In the method, water is flowed through the flow passages, and the flow is interrupted for a period of no flow. This flow profile is repeated such that the water flow is pulsed through the flow passages.
