Bulletin Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 5, рр.27-36. In Rus. The relevance work is caused by need to improve thermal schemes and optimization parameters plants reducing consumption such an resource as natural gas in electricity generation, which will also reduce amount harmful emissions environment. Purpose: carry out, according developed methodology, versatile parametric analysis with choice optimal operating modes proposed their efficiency. Objects: release based turbines chamber. Methods: numerical methods research material balances systems, well elements plants. Results. Based calculation scheme authors compared effect characteristics constant variable turbine plant. It was determined that injected significantly affects range Increasing compression ratio compressor gases at outlet lead decrease comparison operation this case, change vapor increase degree reduced. established same minimum increases net electrical efficiency from 1 % 1600 °С 3 1100 °C.
