Abstract
A method of starting a gas turbine (10) having a combustor (12) and a fuel supply system (14) supplying fuel to the combustor in accordance with the invention includes turning on a fuel valve (40) to control fuel flow to the combustor for combustion after a first starting condition (100) is reached; and cyclically turning (116) the main fuel valve on and off when a sensed exhaust gas temperature (114) initially reaches a first set temperature and continuing to cyclically turn the main fuel valve on and off until the sensed exhaust gas temperature falls to a second set temperature (118) lower than the first set temperature or until a second starting condition (102) is reached.
