Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for supplying a premixed gas fuel/air mixture having a simultaneously controlled ratio of a fuel and air. SOLUTION: An apparatus for use in a system including a gas fuel supply apparatus 30 and a combustor 48 includes a fuel, actuator 130, a control device 34, and a premixer 44. The control device 34 generates an instruction signal indicative of an operation from the fuel actuator 130. The actuator receives a gas fuel from a liquid fuel supply apparatus and supplies a liquid fuel in a regulated flow ratio in response to the instruction signal. The premixer 44 receives a fuel from the fuel actuator 130, and mixes the fuel and air and supplies the mixture to the combustor 48.
