Filed: 1954-03-26
Abstract: 786,058. Liquid fuel burners. FLAVEL & CO., Ltd., S. Oct. 15, 1954 [March 26, 1954], No. 8874/54. Class 75(1) An oil burner comprising a hollow vessel and a pilot burner disposed within such vessel has the oil fed so that at low rates the vaporization and burning takes place only at the pilot burner but when the feed rate exceeds a predetermined value the oil extends or overspills into the main burner vessel and burning takes place at the main burner. The pilot burner 4 of frusto-conical shape is located in a recess of a dished bottom 3 of the main burner 1 and is fed with fuel through a pipe 8, 9 the supply being controlled by a thermostat located in a boiler or water jacket. At starting (after ignition of the burner as described below) the thermostat-controlled fuel valve is fully open and fuel rises in the pilot burner 4 to pass through its perforated walls into the main burner 1 until the boiler reaches a predetermined temperature whereupon the oil supply is reduced by the thermostat to a rate only sufficient to feed the pilot burner 4. Air is supplied to the interior of the pilot burner 4 through a hub 5 and a perforated shell 6 attached to the pilot burner 4 by radial arms 7. The air supply to the burner may be regulated automatically by the boiler temperature. The burner is ignited by inserting a lighted ball of paper through a lighting tube 13 and then closing the aperture 12 thereof by a plug 14. The burner is attached to the boiler by a flange 15 of an extension piece. A flame restrictor comprising a centrally apertured dome supported by legs at its periphery may be carried on the upper side of the extension piece. The flanged extension piece is supported on the burner 1 by a set of distance pieces 17 to provide an annular space 16 through which a secondary air supply is introduced to the top of the burner. An auxiliary pilot burner may be disposed within the pilot burner so that flame increase may be effected in two stages by the fuel supply being adjusted so that fuel first spills over from the auxiliary pilot burner to the pilot burner and then from the pilot burner to the main burner. The oil supply pipe 9 is cleaned by a flexible rod 11.
