GAS TURBINE SYSTEM EMPLOYING STEEL PLANT GAS AS FUEL

A gas turbine system (1), employing steel plant gas as fuel, has at least a combustion air compressor (17); at least a steel plant gas compressor (6); a combustion chamber (14) which receives the compressed combustion air and compressed steel plant gas; and a turbine (20), which is driven by the exhaust gas from the combustion chamber (14) to supply mechanical energy to the combustion air compressor (17), and to a drive shaft (21) connected to the steel plant gas compressor (6) by a transmission (25); the transmission (25) has a connecting/disconnecting device (27) provided with a torque converter for disconnecting the steel plant gas compressor (6) from the drive shaft (21) while the turbine (20) is running.
