Description

Patented June 26, 1928.
UNITED STATES ROBERT C. HOPKINS, OF ALLIANCE, OHIO.
OIL BURNER.
Application filed August 7, 1926. Serial No. 127,916.
The invention relates to oil burners for furnaces and the like, and more particularly to that class of burners in which a blast of air is passed through the nozzle of the burner.
The object of the improvement is to provide an oil burner, through the nozzle of which a blast of air is passed, the oil being admitted to the nozzle through a mixer, connected with a hot tube leading into the combustion chamber of the furnace, whereby the blast of air through the nozzle produces a suction, drawing hot furnace gases into the mixer, where they mix with the incoming oil, atomizing the same and delivering the atomized mixture to the nozzle or burner tip at almost the flash point tlI]1' )G1'itl)Ul@.
An embodiment of the invention is illustrated in the accompanying drawing, in which The figure is a side elevation of the improved burner showing the application of the same to a furnace, portions being broken away for the purpose of illustration.
Similar numerals refer to similar parts throughout the drawing.
A portion of the furnace wall is shown at l, the combustion chamber being indicated at 2, and the opening 3 being provided, to admit the flame from the burner l.
This burner is of the type in which a blast of air is passed therethrough, by any suitable and well known means, in the direction of the arrow shown thereon.
A mixing chamber 5 may be connected to the nozzle portion 6 of the burner, an oil line 7 communicating with said chamber to admit a continuous flow of oil thereto when the burner is in operation.
A tip 8 communicates with the mixing chamber, and is projected into the center of the burnernozzle, preferably at an angle toward the reduced discharge portion of the nozzle, as shown on the drawing.
For the purpose of carrying out the present invention a hot tube 9 is connected to the mixing chamber, and extended through the furnace wall opening, into the combustion chamber, whereby it is in communication with the hot gases of combustion within the furnace.
The flame opening 3 in the furnace wall may be cut away, as shown at 10, to permit a portion of the hot tube to be in direct contact with the flame of the burner, thus maintaining the same at an extremely high temperature.
In operating the burner the continuous blast of air passing through the nozzle will create a suction in the hot tube, continuously drawing the hot gases of combustion through the tube, preheating and atomizing the oil in the mixing chamber, the preheated mixture being drawn from the tip 8 and delivered to the nozzle of the burner at an extremely high temperature.
I claim:
In combination with a furnace having an opening in one side, a burner provided with a nozzle having a reduced discharge portion located at said opening and arranged tohave a continuous air blast therethrough, a mixing chamber, a fluid fuel pipe connected to the mixing chamber, a tube connected to the mixing chamber and opening into the furnace and a nozzle connected to the'mixing chamber and located in the reduced discharge portion of the burner nozzle, the continuous air blast through the burner nozzle producing a suction at the discharge point of the nozzle connecting with the mixing chamber, for drawing gases of combustion from the furnace to the mixing chamber in order to preheat and atomize the fluid fuel in the mixingchamber and deliver it to the burner nozzle.
In testimony that I claim the above, I have hereunto subscribed my name.
