The present invention relates to an open vaporized petroleum heater, by combining a cylindrical burner head ring, which is an anti-dusting means, for preventing the secondary flames from concentrating in the steady state combustion to the center of the radiator, on the upper side of the burner head. Increases the combustion width that forms the stabilizing salt so that the flame heats the upper and lower parts of the radiator uniformly, thereby increasing the amount of radiant heat generated by the radiator to realize comfortable heating, and the burner head ring is glowing by the secondary flame. By transferring heat to the carburetor through the burner head, the operation of turning on / off the preheating heater during normal combustion is unnecessary, which saves power consumption and reduces the generation of tar even during long hours of operation. It is to reduce the generation of harmful gases.
