METHOD OF OPERATION OF GAS TURBINE

摘要

FIELD: gas turbines. SUBSTANCE: gas turbine has air compressor 4, combustion chamber 3 and turbine 5 which drives air compressor 4. Gas turbine may work on combustible mixture calculated stoichiometrically. Air compressor 4 feeds air in amount sufficient for combustion and cooling of combustible gas to permissible turbine inlet temperature due to mixing it with water steam delivered from external steam cycle. provision is also made for operation of gas turbine at intermediate heating taking place between high-pressure turbine 9 and low-pressure turbine 10; waste gas of high-pressure turbine 9 is heated due to heat transfer from gas of combustion chamber before high pressure turbine 9 which is cooled down. EFFECT: enhanced efficiency. 1 dwg
