Aug. 22, 1950 A. G. PARKES BURNER APPARATUS Filed June 25, 1949 INVENTOR.
BY I 0 Patented Aug. 22, 1950 UNITED STATES PATENT OFFICE BURNER APPARTUS Alfred G. Parkes, Toledo, Ohio, assignor to Surface Combustion Corporation, Toledo, Ohio, a
corporation of Ohio 3 Claims.
This invention relates to combustion apparatus and more particularly to an adapter comprising a slender oil Aejecting tube for use with gas burners to permit oil instead of gas to be burned as during severe winter weather when gas is likely to be in short supply.
For a consideration of what I consider to be novel and my invention attention is directed to the following specication and the claims appended thereto.
In the accompanying drawing- Fig. 1 shows the manner of applying the present invention to a well known type of gas burner to permit oil instead of gas to be burned.
Fig. 2 is an enlarged detail sectional view of the present invention.
Fig. 3 is a View on line 3-3 of Fig. 2.
The gas burner with which the present invention has special utility comprises a burner head 5 having an outlet port 6 which forms in eiiect the inlet to a refractory combustion tun- Vnel 'l wherein gas with its full complement of 'air burns to substantial completion before entering the furnace chamber in whose wall 8 the tunnel is ordinarily positioned. The fuel entering the combustion tunnel from the port 6 will ordinarily be ignited by dame issuing from a premix pilot burner I mounted on the casting of which the burner head is comprised.
The burner head 5 will ordinarily comprise a relatively short tubular extension II adapted for connection at its intake end With a pipe T I2 which in turn connects with a fuel supply pipe i3 leading from a source of supply of the airgas mixture which is normally supplied to the burner.
When gas is in short supply the problem is how to switch to oil with minimum trouble and expense. In Jthe present invention this problem is solved by the use of an adapter comprising a relatively slender oil ejecting tube I5 and a supporting head I6 from which the tube extends. As will presently appear, the head I S is hollow and has separate inlets for oil and a gaseous medium for propelling the oil through the tube l5. A threaded extension Il! on said head permits the latter to be screwed into the outer end of the pipe T I2 for support thereby with the tube l5 within the burner head extension Il to discharge the atomized oil through the burner port The oil propelling medium will ordinarily be air under pressure but the amountl of required for this purpose is only a small proportion or what is required for combustion of the fuel. The additional air required iin @Qm-A bustion is delivered under appropriate pressure to the burner head extension I I by a supply pipe which may comprise the pipe I3.
The oil ejecting tube I5 is required to be in line with the burner port but in the absence of special alining means there is no assurance that after the threaded extension l of the tubesupporting head l@ has been screwed into the pipe T I2 the discharge end of said tube I5 will be in proper alinement with said port 6 as iS required for proper functioning of the burner when cil instead of gas is to be burned; hence Athe primary object of the present invention is to provide in conjunction with the adapter a tube-alining means which shall be well adapted for its intended purpose.
The adapter head I6 is a hollow structure defining a chamber l'l wherein the intake end of the oil eje-:ting tube l5 is housed to receive the oil and the propelling medium therefor. The chamber has separate inlet apertures I8 and I9 for said oil and propelling medium, respectively. The supply pipe for the propelling medium is indica-ted at 20, the same having a control valve 2l. The supply pipe for the oil is indicated at 22, the same having a control valve 23. The oil inlet proper is defined by a metering nozzle 2d from which the oil issues as a fine spray. The intake end of the tube I5 has a flaring mouth and is close enough to said nozzle to receive all of the oil spray therefrom. The intake end of said tube l5 is in open communication with the chamber il' hence air entering said chamber from the sup-ply pipe 2@ flows directly into the tube for flow therethrough and thereby propels the oil through the tube and through the multiple orceg 25 in the disk 26 which normally closes the discharge end of the tube. The oil issues from the orifices 25 as a fine mist in a carrier stream of air as will now be readily understood.
The structure which denes the tube supporting head IE is comprised of a base member 33 and a bell type cover 39 removably secured to said member to permit access to the parts within the chamber Il. The base member 38 has a central bore through which the tube I5 freely eX- tends, the bore at its inner end having a spheri- -cal seat 2l for a ball 28. A clamping sleever 29 mounted on the base member 38 is adapted to clamp the ball in adjusted position on said spherical seat. The ball has a tubular stem which at its outerl end is adapted to receive a packing nut 3l to provide a fluid tight joint between the tube I5 and the bore of the ball 28 and to releasably hold tube in position in the borel oi the ball. The normal position of the tube in the ball is such that the mouth of the tube is close enough to the metering nozzle 24 to receive the oil spray therefrom while at the same time permitting unrestricted flow of air to said mouth from the chamber l1. For manufacturing reason the tube I will ordinarily consist of two alined front and rear portions 32 and 33 of r-.f-'hich the rear portion has relatively thinner walls than the front portion. 32 will ordinarily be machined to a standard length whereas the rear portion 33 will be of such length as circumstances may require.
Assuming now that the threaded extension I4 has been screwed tight into the pipe T l2 the procedure to be followed in centering the tube l5 with respect to the burner outlet port is substantially as follows: The bell member 39 is unscrewed from the base member 33 to permit access to the interior of the head IS. The packing nut 3l is released or removed to permit the tube l5 to be withdrawn from the bore of the ball 28. A centering mandrel (not shown) is then inserted in the bore of the ball and extended into the burner outlet 6. The ball clamping sleeve 29 is then screwed tight against the ball to hold it in adjusted position. The mandrel is then with drawn-and the tube l5 reinserted and the clamping` nut 3! tightened to hold the tube in proper axial position in the ball and with respect to the metering nozzle 24. The bell member 39 is then screwed ba k on the base member 39 and the proper connections made with the oil and air supply pipes 22 and 26 as will now be readily understood.
An oil adapter embodying the present invention has the great practical merit of making it possible for even a relatively unskilled workman to quickly align the oil ejecting tube with reference to the burner port 6.
