    摘要: In method for operating a gas turbine (11), the compressed air is fed to a combustor (18, 19) for the combustion of a coal syngas, and the resulting hot gases are expanded in a subsequent turbine (16, 17). Some of the compressed air is separated into oxygen and nitrogen, and the oxygen is used for producing the syngas. In a first combustor, (18) syngas is combusted and the resulting hot gases are expanded in a first turbine (16), and in a second combustor syngas is combusted, using the gases which issue from the first turbine (16), and the resulting hot gases are expanded in the second turbine (17). The two combustors (18, 19) are operated with undiluted syngas, and the first combustor flame temperature (TF) is lowered compared with the operation with natural gas (TNG), while the second combustor (19) is operated in the normal operation (TNG) for natural gas.

    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: The object of the invention is to provide a method for operating a premix burner which has improved operational reliability and functioning during certain types of operation. In addition, it is intended to specify a corresponding premix burner for carrying out the method. According to the invention, this is achieved by the fact that at least one liquid fuel (2) is injected into the inner chamber (9) of the premix burner (4) in a plain jet (26, 26′) with an injection angle &agr; of less than 10°. For this purpose, the liquid-fuel nozzle (17) has a simple injection opening (19) with a guide length (1) and with a diameter (d).
