Abstract : This patent describes an igniter for fuel oil sprays. A plurality of fluidic oscillator or resonance tubes are distributed about a central oscillator opening into one end of a closed chamber. One or more nozzles are located in an end of the chamber opposite the tubes. Compressed gas, such as air, is injected at high velocity from the nozzles into the tubes. The kinetic energy of the gas due to alternating in-and-out flow in the tubes is dissipated as heat transferred to the outer surfaces thereof. When fuel spray impinges on the hot outer surfaces of the tubes, ignition results. The central tube is wrapped with a high temperature resistant cloth. Impinging fuel is soaked into the cloth and vaporized as it is heated. (Author)
