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