- 2In the combustor, air is mixed with fuel (natural gas) and ignited.
- 3The combustion gas rotates the turbine connected to the generator.
- 4Power is generated in the generator connected to the turbine.
- 5The gas turbine is rotated, and the exhaust gas that exits through the exhaust duct is sent to the heat recovery steam generator.
