Method and apparatus for use with a gas fueled combustor

摘要

An apparatus for use in a system having a gas fuel supply (100) and a combustor (48) includes a fuel actuator (130), a controller (34), and a premixer (49). The controller (34) generates a command signal indicative of actuation sought from the fuel actuator for example in response to pressure variations in the combustor (48) as measured by a sensor (22). The actuator (130) receives gas fuel from the liquid fuel supply and provides liquid fuel at a modulated rate of flow in response to the command signal. The premixer (44) receives the fuel from the actuator, mixes the fuel with air, and provides the mixture to the combustor (48). <IMAGE>
