Abstract
An operation method for a gas turbine is provided which includes compressing a working fluid by a compressor, feeding this compressed working fluid into at least one combustion chamber where it is overheated, expanding this overheated working fluid in at least one expansion turbine to produce energy, carrying out a first tapping of the compressed work fluid from the compressor to feed it into a first cavity of the turbine for cooling, carrying out a second tapping of the working fluid downstream from the first tapping to feed it into a second cavity of the turbine upstream from the first cavity, for cooling, and fluidly connecting the first tapping to the second tapping to selectively feed the first tapping by a part of the second tapping during partial load operation conditions to keep the temperature of the first cavity within the acceptable limits for the resistance of the materials.
