Operation method of gas turbine by multistage combustion method and / or sequential combustion method

摘要

The present invention relates to a method for operating a gas turbine by a multistage combustion system and / or a sequential combustion system. According to this method, the burners of the second stage or the second combustor are individually switched on during load increase and switched off during load reduction. At the same time, the total fuel mass and compressor inlet guide vanes are adjusted so that the gas turbine operating temperature and engine power can be controlled to meet the required CO emission target values.
