description: The topic of the final qualification work: "Analysis of the possibility of using steam as a cooler for a high-temperature high-power turbine using the example of GTE-170". The purpose of this final qualification work is to study the possibility of using steam as a refrigerant for cooling a high-temperature high-power gas turbine using the example of the latest domestic turbine GTE-170.1. The guide blade of the 1st stage of the SGT5-2000E turbine (prototype of the GTE-170 turbine) is selected as the object of research and the analysis of changes in the main parameters of the machine after the introduction of steam cooling is carried out, and the efficiency of cooling the blade during steam and air cooling is compared by the temperature values of the metal on the surface of the blade pen. Tasks that are performed in the process of exploring the possibility of using steam as a cooler for the GTE-170.1 turbine 1. Study and analysis of existing methods of cooling high-temperature gas turbines. Theoretical comparison of air and steam as coolers and identification of the advantages of using steam as a working fluid for cooling. 2. Description of the investigated high-temperature stationary turbine of high power GTE-170.1. 3. Performing thermogasodynamic calculations in the ThermoGTE software package for two different control options (temperature preservation behind the turbine and temperature preservation in front of the turbine) based on the available initial calculation of the GTE-170 turbine.1. Plotting the changes in the main indicators of the GTE-170.1 gas turbine installation depending on the load level and ambient temperature, as well as analyzing the various control options obtained. 4. Description of the construction of computational models, setting boundary conditions for air and steam cooling, as well as preparing a project using the ANSYS software package. Construction of grids, setting all necessary conditions for preparation for coupled thermal and gas dynamic calculation in ANSYS CFX. 5. Analysis of the results obtained and a comparative assessment of the thermal state of the wall of the guide blade of the 1st stage when used as a steam and air cooler. This work is considered relevant because, with the resumption of production of domestic turbines, as well as in connection with the withdrawal of foreign manufacturers from the Russian market, there is a need to modernize existing machines, as well as the need to update steam research as a cooler for high-temperature gas turbines using modern software computing systems, as well as for further elaboration of the proposal on the introduction of a steam cooling system for the GTE-170 turbine line.
