Abstract
A gas turbine installation (GTI) consists of 5 main parts: an input device, a compressor, a combustion chamber, a gas turbine, and an output device. In this work, due to the lack of sufficiently extensive information about stationary GTI, data from the characteristics of aviation GTI were partially used. The GTI operation efficiency is influenced by many factors, among which, apparently, the determining factor is the degree of air compression in the compressor π К . Of course, the compression ratio depends on the design scheme of the gas turbine, the type of fuel, the climatic conditions of operation, and others. The most important operational parameter of the GTI is the effective power NP and specific fuel consumption bud . The article provides a numerical analysis of the effect π К on NP and bud under variations in the temperature of gases at the turbine inlet T3 , as well as the influence of other factors, including the selection of part of the air for cooling high-temperature surfaces of the structure. The conclusions were made based on the calculations, the results of which are shown in the tables, and in the comparison graphs of obtained results.
