    摘要: In a method for operating a gas turbine (11) in a combined cycle power plant (40) air is drawn in and compressed through the gas turbine (11), the compressed air is led to a combustor (18, 19) to burn a syngas recovered from a fossil fuel, especially coal, and the gases that result in the course of the combustion are expanded in a downstream turbine (16, 17). In such a method, an improved degree of efficiency is achieved by virtue of the fact that a gas turbine (11) with reheating is used, which includes two combustors (18, 19) and two turbines (16, 17), whereby in the first combustor (18), syngas is burned with the compressed air, and the resultant hot gases, e.g., flue gases, are expanded in the first turbine (16), and whereby in the second combustor syngas is burned by means of the gases coming from the first turbine (16) and the resultant hot gases are expanded in the second turbine (17).

    摘要: Self-excited vibrations can occur in the combustion chambers of gas turbines, which vibrations are due to modulation of the quantity of gaseous fuel or fuel/air mixture as the fuel is injected through a nozzle and into the combustion chamber. The modulation results from pressure fluctuations that occur in the plane of the nozzle. The new fuel lance simultaneously permits both de-coupling of the fuel line in order to avoid combustion chamber vibrations and the possibility of fuel quantity control. The fuel lance comprises an adjustable throttle body that is provided with fuel passage openings and a plunger, the penetration depth of which plunger relative to that of the throttle body is a measure of the fuel quantity flowing therethrough.
