GAS TURBINE PLANT OPERATION METHOD Russian patent published in 2017 - IPC F02C6/00 F01K25/10 

FIELD: energetics.

SUBSTANCE: invention relates to power engineering. Gas turbine plant operation method, including additional circuit with low-boiling working medium, including inlet device, communicated with low-boiling working medium source, heat exchanging device, turbine, communicated with additional drive. Working body, first circuit downstream of inlet device air is cooled down in first heat exchanging device, then after compression in low pressure compressor and working medium further cooling in second heat exchanging device, working medium is expanded to negative temperature in turbine expander and cooled down in third heat exchanging device, after compression in high pressure compressor, combustion in combustion chamber, expansion in turbines of high, low pressures, in power turbine and consumer drive rotation primary circuit exhaust gases are directed into additional circuit heat exchanging device, where low boiling working medium is simultaneously supplied, it is warmed up with primary circuit exhaust gases for head actuation in additional circuit turbine, after that, low-boiling working medium from turbine is supplied into said third heat exchanging device upstream of primary circuit high pressure compressor and then into circulating pump, where low-boiling working medium is compressed, and in liquid state it is supplied for cooling of working medium – air in primary circuit heat exchanging devices.

EFFECT: allows to increase plant efficiency and increase cycle useful operation.
