Abstract: PURPOSE: To prevent a combustion process within a combustion chamber from proceeding towards completion and reduce carbon particles in combustion gas flowing into a gas turbine limiting at least one of combustion reaction parameters, i.e., rate and duration of the reaction process. CONSTITUTION: A high-pressure air tank 22 of an emergency power unit 20 is connected via an air pressure regulator 36, an air temperature sensor 38 and an airflow control valve 40 to a combustor 26, and a fuel tank 24 is connected via a fuel control valve 46 to the combustor 26. Air coming from high pressure air tank 22 is delivered to pressure regulator 36 which regulates the air pressure to an appropriate regulated pressure level controlled by controller 50. The controller 50 performs control by using an air temperature signal from the air temperature sensor 38 to direct the air flow control valve 40 and the fuel control valve 46 to deliver a precise fuel to air ratio to the combustor 26 at appropriate pressures. Due to these constituent features, the time until completion of combustion can be reduced, if required, and carbon particles in discharged flow can be sharply reduced.
