PURPOSE:To make a fuel burning equipment compact as a whole and to prevent an air filter from burning, by setting the long side of an air filter in the upper part of an air duct in the direction crossing the flow of feed air, and by positioning the air suction pipes extended from both ends of an air filter in a zone respectively except the zone over the combustion flames of a burner. CONSTITUTION:A filter case 24a is set in the upper part of an air duct 15 so as to directly cross the feeding direction of air. The middle part of a filter case 24a is connected to the suction port of a fan 20. Suction pipes 25, 25 are respectively extended from both ends of a filter case 24a in the feeding direction of air through the air duct 15, being inclined downward. The starting ends of suction pipes 25, 25 are opened to the directions opposite to the feeding direction of air, and are positioned on both right and left sides of the flames of a burner 8, avoiding the zone in front of and over the flames. Kerosene is stirred and is atomized by a heating cup 17 rotating at high velocity, being gasified by the air fed by the fan 20 through the suction pipes 25, 25 the air filter 24, and an air duct 22, and being burned on an outer cylinder 21. Because the air filter 24 is set in the air duct 15, the title equipment can be made compact as a whole.
