UNITED STATES GEORGE BAKER, OF PERSHING, OKLAHOMA.
COMBINED GAS AND OIL NOZZLE,
Application filed June 9,. 1925. Serial No. 36,030.
T 0 all whom it may concern:
Be it known that I, GEORGE BAKER, a citizen of the United States, residing at Pershing, in the county of Osage and State of Oklahoma, have invented certain new and useful Improvements in Combined Gas and Oil Nozzles, of which the following is a specification, reference being had to the accompanying drawings. 7 v v This invention relates to gas or combined gas and oil nozzles and more particularly to a device of this character intended foruse in combination with a combustion chamber the drum is to be employed includes a comand an air inlet control device constructed in accordance with my copending application for patent on gas burners, Serial No. 36,029, filed June 9, 1925. 1
In the application above identified, I have disclosed a combustion chamber and a fuel drum in axial alignment with the inlet of the combustion chamber and a sleeve slidable upon the drum and inlet and by its position controlling the amount of air admitted for mixture with the fuel as ejected from the drum.
An important object of this invention is to provide a fuel drum of'such character that steam may be employed for supplying pressure to the gas and for injecting the gas into the combustion chamber where the natural pressure of the gas or fuel is not sufficient to enable it to be so used.
A still further object of the invention is to provide a device of this character so constructed that in addition to its function as a means for stepping up the pressure of gas, it may be employed for atomizing and evaporating fuel oilfor use in the burner sothat the burner may continue in use when no gas is available, or the action of the gas may be augmented as is found desirable.
Other objects and advantages will become obvious in the course of the following description. 7
My invention is illustrated in the accompanying drawings wherein Figure 1 is a longitudinal sectional view taken through a burner having a combined gas and oil nozzle constructed 'in'accordance with my invention;
Figure 2 is an enlarged longitudinal sec-f tional vlew'taken through the nozzle struc-' ture; r t
Figure 3 is an end elevation thereof 9 Figure 4 is a section on the line l -4 of Figure 2;
Figure 8 is a section on the line 8- -8 of Figure 7 and Figure 9 is an end elevation of the steam chamber employed in the form of nozzle shown in Figures 7 and 8.
Referring now more particularly to the drawmgs, the general structure with which bustion chamber 10 which is fixed and has an inlet 11 and an outlet 12. The outlet may be provided with a flame spreader 13,
as will be hereinafter more fully set forth,
by an oil line 17. Slidably engaged with the outer surface of the gas drum and the inner surface of the tubular inlet 11 of the combustion chamber is a sleeve 18 which, together with its associated' parts, constitutes the air inlet control means. The construction of this air inlet control means is fully set forth and claimed in the co-pending application above referred to and is merely illustrated in the present instance for the purpose of showing the manner of use of the drum; The drum 14 hasan inlet 19 with which the gas line 15 communicates and which is formed at one end of the drum.
The opposite end of the drum has a wall 20 which has a central aperture 21 and grouped about. this aperture are a plurality of nozzles 22 which project outwardly from this end wall. Arranged within the drum adjacent the end wall 20 is a steam chamber 23 preferably circular inform and having projecting toward this rear wall and in alignment with the bores of the nozzles 22 jet nozzles 24. This chamber has likewise projecting therefrom an axial nozzle .25 which is directed through the axial opening 21 of the end wall and which is of such length that it projects beyond the outer ends of: the nozzles 22. Arranged adjacent the inlet end of the drum is aninletcfitting26 having a T-head, both ends of which-are open .and with one end of which the steam line 16 is engaged. The opposite end of the fitting will accommodate either a steam line leading to a further drum or a plug sealing this end. Interiorly of the'drum, this inlet communicates with a conduit 27 extending longitudinally of the drum and communicating with the chamber 23 adjacent. the lowerendthereofand atthe rear wall thereof. Extending rearwardly from the rear wall of the steam chamber is a semi-circular flange 28 receiving within its b ight the conduit 27, the end of this flange being closed by a wall 29.
Arranged adjacent the inlet end of the drum at the upper surface thereof is an oil inlet 30 which is similar to the steam inlet :26 and which interiorly of the drum comof which is positionedto .discharge into the :trough formed by the .rear wall of the chamber 'the semi-circular flange 28 and the wall 29. Mounted in the walls of the chamber are tubes 32, one of which is arranged at each side of the lowermost nozzle 22 which is vertically below the axis of the drum. Each of these tubes projects from the front face ofthe chamber 23 a short distance and has its endsopen so that-one end is in communication with the trough and the opposite end in communication with the interior :ofthedrum 14 adjacent the wall thereof.
In the use of this form of any .device, whengasalone is being used,-steam entering through the inlet and passing through the chamber is injected at the nozzles 2st and passing through the nozzle 22, because of the form of these nozzles, sets up a suction within the drum, withdrawing gas from "the drumand reducing the pressure of the drum so that low pressure gas will readily enter thereinto. At the same time, the steam and gas are thoroughly mixed and in passing from the nozzles will be further mixed with air entering through openings formed in the sleeve theamou-nt of air which is mixed depending upon the adjusted position of the sleeve. The central steam =nozzle will serve to produce a blast and a tendency toward a vacuum at the nozzles 22 so that the mixture :ejected from these nozzles will be drawn into the steam passing from the nozzle 25 and thoroughly mingle therewith. The gas being heated will, .of course, ignite very readily and will provide a steady hot flame at the outlet 12 of the combustion chamber. When oil is being used, the oil passing from the pipe 31 into the trough is highly heated with the result that a cer-. tain proportion thereof is vaporized and passes off with the gas through the nozzles 22. The remainder of this oil througl'i the suctioncreate'd at the nozzle end of the ,drun Will be drawn off in the form of a spray and v intermingle with the gaseous fuel and steam. In the combustion chamber, the additional heat supplied together with the steam will serve "to completely evaporate this oil so that ,gas is supplied at the outlet 12 for burning. It will be obvious that where no oil isito be employed in the burner, the form of construction shown in Figures '7 to 9 may be employed, the trough formed by the flange 28-and end wall-29 and the oil inletand conduit 31 being eliminated as are the tubes 32.
With a device of this character, I preferably provide at the outlet vof the burner a spreader such as more-clearly shown in Figure 1. This spreader-is formed by .providing the outlet 12 which is tubular with an outstanding flange 33, the outer edge of which is raised above the inner edge so that a dish effect is obtained. :Supported in alignment with the outlet-is a concaved disk 314 having an axial opening and above this disk is arranged a solid concaved disk 36, the concave'd seats of the'diskbeing arranged upwardly. Tn supportingthedisks, 1 preferably provide .a rod 37 axially directed through the outlet 2 and threaded at its lower end in the wall of the combustion chamber.
To the outer end of .this'rod, the disk 36 is threaded and the outer edge of this disk has depending arms 38, the .lower ends of which are secured tothe disk 34. With a spreader of this character, a portion of the contents of the combustion chamber will pass outwardly between the disk 3% and the flange 33 while the other portion thereof will pass through the opening 35 and impinge against the lower face of the disk 36 and pass out between the disks 35 and .36, thus providing adouble circular flame which the pressure of the blastemitted when steam is being employed to provide means for drawing gases into the gas drum.
Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of my invention, I do not limit myself to such specific structure except as hereinafter claimed.
