Patented Sept. 8, 1931 UNITED STATES PATENT OFFICE JOHN P. LEASK, OF GLENIBROOK, CONNECTICUT, ASSIGNOR TO PEABODY ENGINEERING CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK OIL BURNING SYSTEM Application filed July 21, 1928. Serial No. 294,464.
My invention relates to oil burning systems and more particularly to'means for varying the capacity of the atomizer, thatis, for varying the amount of oil atomized per burner per hour. The desired Variation is eifected by providing the atomizer with a plurality of independent oil passages and controlling the ports of said passages by a valve or valves. the position of which is determined by the pressure of the oil in the supply line. The invention will be under stood by reference to the accompanying drawings in which Fig. 1 is a longitudinal section on the plane of the line 1-1 of Fig.
5 2 through the rear end of an atomizer havmg means thereln for controlling the distribution of the'oil to the tip; Fig. 2 is a transverse section on the plane of the line 22 of Fig. 1; Fig. 3 is a transverse section on the plane of the line 3-3 of Fig. 1; Fig. 4 is a view similar to Fig. l on the plane of the line 44 of Fig. 5, showing a modified form of atomizer; Fig. 5 is a transverse section on the plane of the-line 55 of Fig. 4; Fig. 6 is a diagrammatic view of a boiler front showing the layout of a system in which the atomizers may be used. reference numerals indicate smiliar parts in the several views.
In F ig. 6 I have, for convenience of description, illustrated the layout of a system in which the invention may be employed. In this figure the letter a designates a boiler having three atomizers b, 0, and d installed therein. The source of fuel supply is through main line 6 to branches 6, e 0 The main line may have therein a valve f automatically controlled by the steam pressure through a diaphragm regulator g. Manually operated valves it may be placed in the main line and in a by-pass 2' thus permitting the oil to flow to the branch connections either through the main line or through the bypass. It is to be understood, of course, that the installation may be equipped with any number of atomizers and that the means hereinafter described may be set to deliver the oil from the main supply line at the same pressure to all of the atomizers of the installation. Stated generally, my
Similar invention utilizes the pressure of the incoming oil itself to control the amount permitted to flow to the atomizer. This control may be effected at any desired point in the oil supply line. One means for so doing is illustrated in Figs. 1, 2, and 3, in which the numeral 1 designates a portion of a burner barrel which, in practice, will be connected to the main supply line directly when there is butone atomizer, or through a branch pipe when there are a number of atomizers in the installation. The burner barrel is exteriorly threaded at its rear end to receive a cap 2 and is bevelled as shown at 3 to provide a seat for a plug 4. The face of the plug is preferably fiat and upon it is seated a tip 5. The latter has a bevelled shoulder at 5 so that the tip will be centered and held in proper position when the cap is screwed upon the burner barrel. A dowel pin 6 secured to the plug 4 and entering a hole in the tip insures proper registration of passages in the plug and tip as hereinafter described. I
The tip is formed with a central chamber 7 and a discharge orifice 8. Formed in the flat face of thetip, and entering substantially tangentially to the wall of chamber 7, are ducts 9, 10, 11 and 12. When the parts are assembled, these ducts are in communication, respectively, with passages 13, 14, 15 and 16 in the extension 17 of the plug 4. The said passages are closed at their forward ends and open at their rear ends as shown in Fig. 1, The extension 17 is formed with a chamber 18 in the end of which is a fixed bushing 19 to limit the outward movement of a valve 20 slidably fitted within said chamber. Between said valve and the rear end wall of chamber 18 is a spring 21 adapted to normally hold the valve against bushing 19.
The passages 13, 14, 15 and 16 communicate with chamber 18 through ducts 13, 14, 15',
and 16, respectively, in the wall between said chamber and passages. These ducts are located along the wall of chamber 18 a suitable distance apart and in different planes as viewed in Fig. 1. By reason of the concentric disposition of the passages 13, 14, 15 and 16 around the chamber 18 the admission of oil from the hurner barrel toc'hamber 18, andq the outflow of the oil from said chamber, is
' ducts 13', 14, 15', and 16C",
determined by the position of valve 20 under the pressure of the entering oil. The tension of spring 21 is so adjusted that when the oilsupply in the main line is completely cut off, valve 20 will be seated against bushing 19. When the oil supply line is open, the
position of valve 20in chamber 18 will be determined by the pressure of the oil and the valve will be moved, against sprin 21, to uncover one or more of the ports the Assuming a line 'pressure'of 50 lbs. per
square inch, the duct 13 will be so located that the movement of valve 20, under such pressure will open the port of said duct to permit the flow of oil from chamber 18 to to open duct 14 thus admitting an additional amount of oil which will reach chamber 7 through tangential duct 10. Upon a further increase in the oil pressure, the ducts ,and 16' will be opened to thus admit the maximum amount of oil to the tip chamber. With the valve at the extreme outward limit of its movement a decrease in the capacity of the atomizer will be effected by reducing the oil pressure and thus closing one or more of the ducts leading from the chamber 18 to the passages 13, 14, 15, and 16. As the oil pressure is decreased the spring 21 will act to move thevalve. toward its seat on bushing 19. From the foregoing description it will be seen that I secure a wide range in capacity by successively opening or closing a series of passages leading to the tip chamber and determine such opening and closing by the pressure of the oil in the main supply line.
Where there are a plurality of atomizers the tension of the several springs 21 may be the same or difierent. If the same, the valves 20 will, of course, be moved to the same extent in all of the atomizers at the same time as the main line pressure is varied. If desired, however, the tension of the springs in the several atomizers may differ one from the other so as to vary the extent of movement of its corresponding valve 20. In that case the capacities of the several atomizers will be correspondingly varied.
While I have shown four passages surrounding chamber 18 it is obvious that there may be a greater or less number with corresponding changes in the number of tangent7ial ducts leading into the tip chamber Instead of forming the plug extension with a central supply chamber 18, I may employ the construction illustrated in Figs. 4 and 5 passages are the same as in Fig. 1. passages 22, 23, 24 and 25 communicate with in which the plug extension 17 is formed with four independent passages 22, '23, 24 and 25 opening directly from the burner barrel 1. Fixed in the outer end of each of said passages is. a bushing26 having ribs 26 ropassage. I
The burner barrel, cap, tip, and tangential The the respective tangential passages to deliver the oil to thetip chamber 7. In this modified form, the amount of oil admitted to the tip chamber is regulated by the tension of the springs 28 in the several passages. That is, assuming the spring 28 in passage 22 of such tension as to permit the opening of valve 27 under a pressure of lbs. per square inch, acertain number of pounds of oil will be permitted to flow to the tip chamber. The
As far as the principle is concerned, the method of operation of the two forms of atomizers shown is the same. In both it may be said that the oil is delivered to the atomizer from the main supply line through independentpassages, and that the admission of oil to said passages is automatically controlled'by the pressure of the oil in the main line.-
What I claim is:
1. An oil burning system comprising a source of fuel supply, an atomizer having a tip and a plurality of independent oil passages leading thereto, a pipe line connection from the source of supply to the atomizer, and means for successively opening said passages actuated by the pressure of the oil in the pipe line.
