Abstract
A method is described for the start-up of a gas turbine comprising the phases of effecting a preliminary purging cycle of the discharge duct () of the turbine (), establishing a predetermined minimum value (FSR) for the flow of gaseous fuel entering the combustor () for a period of time which is adequate for effecting a first attempt at ignition and effecting a first attempt at ignition, effecting an intermediate purging cycle of the discharge duct (), interrupting the flow of gaseous fuel to the combustor (), and progressively increasing the value (FSR) of the flow of gaseous fuel entering the combustor (), effecting further attempts at ignition until the mixture of air/gaseous fuel has been ignited and the consequent start-up of the turbine (), or until a predetermined maximum value (FSR) of the flow of gaseous fuel has been reached.
