Abstract
A combustion control system controls a turbine engine that includes a fuel manifold and a plurality of fuel injectors. The control system includes a fuel pulsator and a controller. The fuel pulsator is coupled in flow communication with the plurality of injectors and the fuel manifold. The controller is coupled to the fuel pulsator such that the pulsator is between the controller and the fuel manifold. The controller is variably selectable and configured to facilitate promoting stable combustion.
Claims14
A combustion control system for controlling a turbine engine including a fuel manifold and a plurality of fuel injectors, said control system comprising:
- a fuel pulsator in flow communication with said plurality of injectors, and said fuel manifold;
- and
- a controller coupled to said fuel pulsator, said controller variably selectable and configured to facilitate promoting stable combustion without receiving continuous feedback from a combustor.
A gas turbine engine comprising:
- a combustor defining combustion chamber;
- a fuel manifold;
- a plurality of fuel injectors in flow communication with said fuel manifold, said fuel injectors configured to supply fuel to said combustion chamber;
- and
- a fuel control system coupled to said fuel manifold and said fuel injectors, said fuel control system comprising a fuel pulsator and a controller, said fuel pulsator in flow communication with said fuel manifold, said controller coupled to said fuel pulsator such that said controller does not receive a continuous feedback signal from said combustor.
