摘要： A nozzle for a fuel injector, in particular for a gas-turbine engine, is provided comprising a planar conductive electrode with a sharp edge forming an aperture, an upper insulation layer above the electrode and a lower insulation layer below the electrode, both insulation layers having apertures, and a swirler arrangement for creating a swirling action in liquid fuel introduced into the nozzle. The axis of swirl is generally perpendicular to the plane of the electrode. In use, the swirling fuel passes through the aperture of the lower insulation layer, the aperture of the conductive electrode and the aperture of the upper insulation layer. As the fuel passes through the aperture of the electrode, the electrode charges the swirling fuel, so that the nozzle supplies charged droplets of atomised fuel from an outlet orifice. The swirler arrangement may be a radial or axial swirler arrangement.

摘要： A burner for a gas-turbine engine including a swirler and a combustion chamber is provided. The swirler includes a plurality of vanes arranged in a circle, each adjacent pair of vanes defining a flow slot for the flow of air and fuel into the swirler, the air and fuel is mixed and supplied in swirling form to the combustion chamber. The swirler can also include a partitioning device which divides the flow of air along each flow slot into two air flows. One side of the partitioning device has a fuel-supply port for supplying fuel to one of the two air flows. The relevant air flow causes fuel supplied to the fuel-supply port to form a film of fuel over the relevant side of the partitioning device. The film leaves the relevant side of the partitioning device in a region of high shear between adjacent flows in the burner.
