GAS TURBINE PLANT Russian patent published in 2000 - IPC

FIELD: heat power engineering; heat regeneration. SUBSTANCE: gas turbine plant includes at least one gas turbine, heat exchanging device for heating compressed gas by heat from heat source, device for delivering heated compressed gas to turbine for expansion of gas and conversion of its energy into kinetic energy in gas turbine, and isothermal gas compressor. The latter is set into operation by pneumatic drive. Compressor is furnished with device forming atomized liquid jet in compression chamber for cooling gas at compression. Liquid is removed from cold compressed gas getting out of compression chamber by means of moisture separator. Rotary compressor or combustion chamber can be used as pneumatic drive. Proposed plant has main line heater furnished with combustion chamber or external heating source. Plant can be provided with second and third gas turbines and device for delivering part of cold compressed gas to blades of gas turbines for cooling the blades to obtain higher temperature at turbine inlet. Additional gas turbines and auxiliary heat exchangers should be smaller than main components of system. Gas turbine plant can be furnished with thermocompressors, closed and open cycle compressor. Heat is supplied to compressors by injecting of hot liquid. Moreover, thermocompressor can be includes into energy generation and gasification cycle. Compressor has pistons and housing of different designs and it can operate as reversible machine. EFFECT: increased efficiency and economy of plant owing to use of compressors of different design versions. 16 cl, 18 dwg
