Description
Summary:The comparative analysis of conventional schemes of gas turbine units of simple and complex cycles with intermediate air cooling by water injection and proposed schemes with aerothermopressor is carried out. A principle of cooling with the use of aerothermopressor effect, or so called, thermogasdynamic compression, is in increase of gas (air) pressure during instantaneous evaporation of water, injected into gas (air) stream accelerated up about to the sound velocity. The results of calculations has shown that the use of aerothermopressor allows to increase the efficiency of the gas turbine units with regeneration by 0,5…2,0 %, and for the units of complex cycle with stage compression and expanding – by 2,0…4,0 %.
