ABSTRACT:
A gas turbine combustor for a gas turbine plant comprises an outer casing and a combustor liner disposed in the outer casing, the interior of the combustor liner constituting a combustor chamber divided into a first stage of combustion area and a second stage of combustion area, disposed downstream of the first stage combustion area. The gas turbine combustor further comprises a nozzle member for supplying a first stage fuel into the first stage combustion area, a header for supplying a second stage fuel into the second stage combustion area, and a header for further supplying water or water vapor into the first stage combustion area. The nozzle member and both the headers are disposed in an end plate closing one end of the outer casing in a concentrical fashion. The flow rates of the first and second stage fuels and the water vapor are controlled by a control unit equipped with the gas turbine combustor.
