The present invention relates to a pressure spraying type hybrid flame oil burner used as a heat source for a far-infrared light oil heater, an open type oil stove, an oil combustion device, or the like. The hybrid flame oil burner of the present invention, in a port type oil burner which comprises: a burner port (1) in the shape of a bowl having a side wall unit and a closed wall; and the side wall unit of the burner port (1) having an air (1a) inlet hole for combustion and the closed wall of the burner port (1) having a fuel spray inlet hole (1b), and which sprays an atomized liquid fuel with a pressure spray nozzle (4) inside, comprises: an evaporation tank (2) in the shape of a cup covering the fuel spray inlet hole of the burner port for supplying atomized fuel with air to have an outlet hole for a pre-mixed gas divided into a front line and a rear line, which is placed close to the burner port on the same central line as that of the fuel spray inlet hole of the burner port. The second pre-mixed gas outlet hole of the front line works as a flame hole of the pre-mixed combustion to form a pre-mixed flame, and, simultaneously, the first pre-mixed outlet hole of the rear line conducts a spreading combustion by inducing the pre-mixed gas leaked up to the inlet hole for air for combustion of the burner port. As two types of flames are used, the spreading combustion volume of the burner port, which is the major combustion part, is reduced and the external diameter of the burner is reduced. |
