Gas turbine with improved part load emissions behavior

摘要

In a method for the low-CO emissions part load operation of a gas turbine with sequential combustion, the opening of the row of variable compressor inlet guide vanes (14) is controlled depending on the temperatures of the operative burners (9) of the second combustor (15) and simultaneously the number of operative burners is kept at a minimum. This leads to low CO emissions at partial load of the gas turbine.
