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： A method for operating a gas turbine (11), which is used especially in a combined-cycle power plant (30), includes inducting and compressing air by the gas turbine (11), the compressed air is fed to a combustor (18, 19) for the combustion of a syngas which is produced from coal, and the hot gases which result during the combustion are expanded in a subsequent turbine (16, 17), performing work, wherein some of the compressed air is separated into oxygen and nitrogen, and the oxygen is used in a coal gasification plant (34) for producing the syngas. With such a method, a reduction of the NOx emission is achieved without noticeable loss of output and flexibility of operation by a gas turbine (11) with reheating being used, which includes two combustors (18, 19) and two turbines (16, 17), wherein in the first combustor (18) syngas is combusted, using the compressed air, and the resulting hot gases are expanded in the first turbine (16), and wherein in the 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 flame temperature (TF) in the first combustor (18) of the gas turbine (11) is lowered compared with the operation with natural gas (TNG), while the second combustor (19) is operated largely in the normal operation (TNG) which is designed for natural gas.

摘要： A fuel lance for a gas turbine installation with sequential combustion, in which hot gas is produced in a first combustion chamber and expanded in a subsequent turbine, and then flows through a subsequent second combustion chamber in which the fuel lance for injecting fuel into the hot gas is arranged. The fuel lance has a lance section which extends in the flow direction of the hot gas and includes at least an outer tube which is arranged concentrically to a lance axis, and a center tube which is concentrically arranged in the outer tube and in which the fuel is guided to the lance tip and is injected through first injection openings in the region of the lance tip into the hot gas. The fuel lance is modified for operation with syngas by the first injection openings being arranged directly on the lance tip, and by the first injection openings being oriented so that the fuel jets which emerge from them include an acute angle with the lance axis.

摘要： A method is provided for operating a gas turbine power plant with flue gas recirculation, in which the flue gases are split into a first flue gas flow for recirculation into an intake flow of the gas turbine and into a second flue gas flow for discharging to the environment. The first flue gas flow is cooled in a recooler before its mixing with ambient air for forming the intake flow. The recirculation flow, after being recooled, is reheated in order to avoid condensation of vaporous water contained in the recycled flue gases during cooling as a result of the mixing with the ambient air. A gas turbine power plant is provided with flue gas recirculation, which includes a heat exchanger for reheating the recirculation flow after being recooled.
