FUEL AIR PREMIXER USING ROTARY INJECTOR AND GAS TURBINE COMBUSTOR WITH FUEL AIR PREMIXER USING ROTARY INJECTOR

摘要

The present invention relates to a fuel air premixer using a rotary injector and a gas turbine combustor with the same which maintain low fuel supply pressure regardless of engine power by installing the rotary injector, which can be applied to a cylinder combustor and a ring-shaped combustor and control rotation speed, in the premixer of the gas turbine combustor, and supply air and fine fuel particles to the combustor by uniformly mixing the air and fine fuel particles injected regardless of the engine power by centrifugal force generated when the rotation speed of the rotary injector is controlled. The fuel air premixer using the rotary injector of the present invention comprises: a mixer tube which is arranged at the front of a combustion chamber and is connected to the combustion chamber; a fuel injection part which is arranged in the mixer tube and sprays fuel to the inner space of the mixer tube by rotation; a fuel supply part which supplies fuel to the fuel injection part; a first swirler which is arranged around the fuel injection part by being installed at the front of the mixer tube and supplies air to the mixer tube; a second swirler which is installed at the rear of the mixer tube and discharges fuel air mixture gas within the mixer tube to the combustion chamber; and a motor which spins the fuel injection part regardless of power generated by a turbine part.;COPYRIGHT KIPO 2014
