ABSTRACT:
An apparatus and method for determining and maintaining the temperature of a primary zone of a combustor of a gas turbine engine at a predetermined level is provided. A first sensor senses the inlet air temperature of the combustor, a second sensor senses the inlet temperature of the turbine gases, and a third sensor senses the speed of or measures the load of the engine. Based on the first and second sensed temperatures, the speed or the load, and the preestablished combustor design parameter, the primary zone temperature of the combustor T.sub.pz is calculated. A controller maintains the combustor at a predetermined setpoint temperature by moving an air bleed valve between open and closed position, or a plurality of inlet guide vanes between open and closed positions.
