Abstract
In a method for the low-CO emissions part load operation of a gas turbine with sequential combustion, the air ratio (λ) of the operative burners () of the second combustor () is kept below a maximum air ratio (λ) at part load In order to reduce the maximum air ratio (λ), a series of modifications in the operating concept of the gas turbine are carried out individually or in combination. One modification is an opening of the row of variable compressor inlet guide vanes () before engaging the second combustor (). For engaging the second combustor, the row of variable compressor inlet guide vanes () is quickly closed and fuel is introduced in a synchronized manner into the burner () of the second combustor (). A further modification is the deactivating of individual burners () at part load.
