A gas turbine has a fuel injection system for supplying pressurized fuel gas to a combustion chamber (2) of a gas turbine, the fuel injection system having at least one electrically controllable magnetic valve (3, 4, 5) working with pulse-width-modulation, i.e. controlling the gas flow by varying the length of its opening time pulses in relation to its closing time, in a gas supply conduit (15). The fuel injection system has at least one electrically controllable magnetic main valve (3, 4) arranged in the supply conduit (15). Moreover, at least one pilot valve (5) is connected to the supply conduit with its upstream end after the main valve and with its downstream end connected to a conduit (17) leading into a pilot flame chamber (19) inside the combustion chamber (2). |
