Abstract:
1. A combustion dynamics control system, comprising: a fuel injector for receiving a premixed fuel via a premixed fuel injector coupled directly to the fuel injector, wherein the premixed fuel injector comprises a premixed fuel injection orifice; an acoustic driver for generating an acoustic pressure node in the fuel injector at a location of the premixed fuel injection orifice, wherein the acoustic driver is coupled directly to the fuel injector upstream of the premixed fuel injector orifice; a sensor for measuring acoustic pressure in the fuel injector solely at the location of the premixed fuel injection orifice; a signal conditioner for conditioning the sensor signal and for generating a conditioned sensor signal there from; and a controller for controlling the acoustic driver, wherein the acoustic driver generates the acoustic pressure node in the fuel injector at the location of the premixed fuel injection orifice based on the conditioned sensor signal.
