Description
Dec. 8, 1936. H. P. PARRIGIN `GAS FUEL BURNER Filed Sept. 17, 1954 irme/vir Patented Dec. 8, 1936 UNITED STATES ,PATENT OFFICE 2 Claims.
My invention relates to improvements in gas fuel burners and the main object is to provide a burner of simple and practical form suitable for use with either low or high pressure fuels.
Another object is to provide a burner of this kind so constructed as to ensure a uniform distribution of air and fuel mixture at all times, to provide a thorough mixing of the fuel and air, and which has no small ports or passages which so often clog up and prevent the operation of a burner.
A further object is to provide a burner having an improved novel and ecient air and fuel mixing assembly wherein the rush of fuel into the burner draws in air and mixes therewith and having also an ecient and novel form of burner or ejector tip having either one or two adjustable ports allowing convenient (and external) adjustment of the exit velocity of the air-fuel mixture so as to vary the spread and length of the flame.
A further object is to provide a burner which is relatively small in size and extremely simple in construction so as to facilitate its installation and its maintenance and which allows it to withstand high furnace temperatures due to its excellent cooling of all parts.
Still a further object is to provide a burner of the foregoing characteristics which comprises a mixing assembly and a burner tip assembly which are separated and connected by a pipe or conduit, the mixing assembly comprising a fuel inlet nozzle supported coaxially within a housing having an annular air inlet port around the nozzle, and the said burner tip assembly comprising a housing and deectors supported in the housing and adjustable to form an annular port around the end of the housing.
With these and other objects in view the invention resides in the novel construction and arrangement of parts as hereinafter fully set forth and claimed, reference being had to the accompanying drawing wherein:
Figure 1 is a medial longitudinal section through one practical form of my burner showing the fuel inlet pipe attached thereto.
Figure 2 is an end view of the burner tip assembly.
Figure 3 is a cross section along the line 3--3 in Figure 1.
Figure 4 is a cross section along the line 4--4 in Figure 1.
Referring now with more particularity to the drawing my invention comprises, a fuel and air mixing assembly designated generally at I0, a
.burner tip assembly II and a connecting pipe or barrel I2. These parts may all be integrally formed. The said mixing assembly I includes a housing I3 threaded at one end I4 on the end of the barrel I2 and flaring or enlarging outward at I6 towards its mouth Il. A fuel nozzle I8 having a tapering nose I9 is supported coaxially just within the mouth Il by wings or ribs extended and fastened radially between the nozzle and housing, the outlet opening 2I of the nozzle being turned inward into the housing I3. The nozzle I8 is also threaded internally at its outer end at 22 to receive the fuel supply pipe 23 and an air inlet adjusting plate 25 is slidably mounted on the nozzle.
The burner tip assembly II also includes a housing 26 which is cylindrical and is internally threaded at one end 2l to screw on the other end of the barrel I2. A spider or radially extended supporting ribs 28 is mounted in this housing 29 and carries a hub 29 having a threaded bore 30 to receive the threaded stem 3| of a deflector ring 32 which is of a diameter substantially larger than the internal diameter of the housing 26. The inner face 33 of this deflector ring 32 is beveled off and cooperates with the flaring mouth 33a of the housing 26 so as to deflect the fuel outward through the annular opening or port 34 formed between these parts,
this opening being of course readily adjustable o by screwing the stem 3| inward or outward in the bore 39. This ring 32 carries a spider 35. having a central threaded socket 36 in which the threaded stern 31 of an outer deflector 38 may be screwed. This delector 38 is in the 3,
form of a disk substantially larger in diameter than the inner diameter of the ring 32 whereby an annular opening 39 is formed as shown.
In operation the fuel is admitted to the nozzle I8 through the pipe 23 (under control of a valve therein) and the inrush of fuel into the housing I3 through the opening 2| sucks or draws in air thru the annular opening or mouth I1 of thehousing. The amount of air drawn in may be adjusted by moving the plate 25 toward or away from the housing to close or open the mouth I1 to any extent. The mixture of fuel and air thus formed passes through the barrel I 2 and emerges from the opening or port 34 aroundr the deilector ring 32 and then is further mixed with air around the burner and burns in a flame which may be adjusted in length and breadth by the aforesaid adjustment of the deflector 32. At the same time the fuel mixture emerging from the said opening 39 will burn in a similar manner. It will be noted that the mixture flowing from the opening 34 Will be directed forwardly at an outward angle and the mixture rushing from the opening 39 will strike this flow and the gas will be further mixed. It is an important feature that this form of burner forms a shorter flame than the burners now in use thus making them suitable for short furnaces and similar applications.
It is thought that further details of the operation, utility and advantages of my invention will be understood by those skilled in the art and While I have herein set forth a certain preferred embodiment of my invention, it is understood that I may vary from the same in minor structural details, so as best to construct a practical device for the purpose intended, not departing from the spirit of the invention and within the scope of the appended claims.
I claim:
l. In a device of the kind described, a barrel, a housing mounted on one end of the barrel and flaring outward towards its outer open end, a nozzle supported coaxially within this open end of the housing, a plate adjustably supported adjacent to and coaxially with the nozzle and adapted to partially close the open end of the housing, and a fuel mixture ejecting and deecting means at the opposite end of the barrel, the same comprising an open cylindrical housing mounted on the barrel, a hub coaxially supported in the housing, and having a threaded bore, a deflector comprising an annular shell and a spider mounted within the shell, the said spider having a threaded socket opening at one side and a threaded stem extended from the other side and threaded in the bore in the hub, a at disk-like outer deector plate, and a threaded stem extended from this deflector plate and threaded in the said socket.
2. In a device of the kind described, a barrel, a housing mounted on one end of the barrel and flaring outward towards its outer open end, a nozzle supported coaxially within this open end of the housing, a plate adjustably supported adjacent to and coaxially with the nozzle and adapted to partially close the open end of the housing, and a fuel mixture ejecting and deflecting means at the opposite end of the barrel, the` same comprising an open cylindrical housing mounted on the barrel, a hub coaxially supported in the housing, and having a threaded bore, a deflector comprising an annular shell and a spider mounted within the shell, the said spider having a threaded socket opening at one side and a threaded stem extended from the. other side and threaded in the bore in the hub, a flat disk-like outer delector plate, and a threaded stem extended from this deector plate and threaded in the said socket, the outer end of the housing being ared out and the adjacent edge of the deector shell being beveled off to guide the fuel mixture outwardly and forwardly into the mixture emerging between the saidshell and the outer deflector plate.
