Abstract
A fuel control system for a dual-shaft gas turbine engine having a gasifier turbine and a power turbine comprises a device for supplying fuel to a combustor of the engine by an amount necessary for engine ignition during engine starting. Under normal operating conditions, fuel is supplied to the combustor by a closed loop controller. An accelerating device increases the fuel supply to the combustor as time progresses from a first time when engine ignition takes place to a second time when the closed loop control of fuel supply takes place, thereby shortening the time period required for the engine to reach normal operation.
