Abstract

New thermodynamic cycles of open gas turbine plants (GTP) are proposed: cycle with broadening gases into turbine to pressure lower than atmospheric and cycle with preliminary cooling of air sucked by compressor. Calculations showed, that work and thermal coefficient of efficiency of GTP at broadening of gases into turbine to pressure lower than atmospheric (0,05 MPa) increased on 19,7 and 24,5 % correspondingly. At cycle with preliminary cooling of air to temperature minus 30 ºС work of cycle increased on 17,6 %. Thermal coefficient of efficiency at this case not changed, because degree of rise of pressure not changed. Taking into account, that processes of cooling gases and air at proposed cycles are «free of charge», some constructive complications of modified GTP are fully justified by such essential increase of basic characteristics of cycles
