Abstract
Increasing concerns about energy and emissions from fuel consumption in gas turbines has
attracted many researchers to protect the environment and reduce pollutants in the world. The
main objective of this paper is to investigate the increasing efficiency of three-stroke gas turbine
operation based on the technical analysis of the operation of three-axis gas turbine cycles with
non-design conditions in partial loads, taking into account environmental criteria and sustainable
development. Three-axial gas turbine has been studied and thermodynamic modeling and the
database has been formed and completed for all constant and variable parameters. Then, the
objective function (increased efficiency and gas turbine power) is defined and the objective
function is optimized by connecting the databases and using the genetic algorithm. After
thermodynamic modeling for different values of the position of the input guide blades and the
position of the three-stroke gas turbine drainage positions, the efficiency of the gas turbine and
the efficiency of genetic algorithm increased. Based on the results, NOx emissions were
compared to the various partial gas loads of the gas turbine. It was observed that with the help of
this optimization, NOx emissions were reduced. In this sense, using this optimization has been
instrumental in environmental protection. The application of this research in the country's power
industry and gas turbine power plants is used to increase the efficiency and power and hence
reduce air pollution.
