burner supports and more especially to sup-.

ports for oil and gas burners used in conjunction with metallurgical furnaces.-

It is an object of the invention to rigidly and correctly apply burners to furnaces 7 Another object is to provide adjustable means for varying the distance between burner outlet and furnace wall.

.-A further. object is to obtain accurate .alinement of burners with respect to their combustion chamber, and to maintain this accurate andproperalinement during their adjustment withthe furnace'wall.

. Another object is to provide means to shut .oflithe fiame inlet opening of the furnace when the burner is not in use for the purpose of retaining all heat possible within the furnace while the burner 1s not at work.

fOtherobjects of the invention will appear in the following. specifications in which a preferred form of ny burner support is described.

My invention refers more particularly to application with. burners so designed and constructed as to provide minute atomization andthorough mixture at their outlets. In these burners ignitionresults almost instantaneously. Combustion is, rapid. The opening through the furnace wall serves as a combustion chamber which should be carefully proportioned and exactly sized. These devices known as mechanically atomizing burners, depend upon high pressure coacting with a spray nozzle to break up the oil into 'a mist, or fog. The most improved type of these burners utilizes air at very low pressure for supporting combustion. This is projected at a suitable angle into the oil mist in proper proportion, instantly forming a highly combustible mixture. k The explosive characteristics of the resulting flame demand careful adjustment of the burner with respect to the furnace wall and accurate alinement with respect to the comb a @h m r,

terbeing-indicated in broken lines;

Inburners of the class described a rigid support fastened to the furnace wall is mechanical necessity. r

To be of maximum efficiency ignition must occur within a limited travel of the-vapor mist. The burner characteristics combined w1th furnace design and method of operating, determine the desired travel. The support therefore must be adjustable to vary the distance between burner outlet and furnace wall to suit different applications.

I attain the objects above described by means of the device illustrated in the accompanying drawing in-which Figure 1 is a vertical longitudinal sectional view of the burner. support withpart of a burner indicated to'illustrate the application and showing a fragmentary section through part of the furnacewall 1 Fig. 2 is an end view of the burner support'proper, the open positionfiofjthe shut- Fig. 3 is a cross sectional view along-the plane of line 3-3 in Fig. 1.; 4

10 1s 'a burner of the externally mixing class. 11 is an oil discharge nozzle. 12 is an air deflecting plate. The furnace end of the burner 10 is exteriorly threaded at 13, to receive-an air deflecting cap 14. All ofthese parts are common to the externally and mechanically atomizing kind of burners, now known in the art as Anthony burners. a i

15 is a part section of the metal shellinclosing the fire bricks, forming the furnace walls proper, of which 16is a fragmentary section.

17 is a ring threaded internally at 18 .to screw onto threaded part 13 of the burner 10. Attached to the ring. 17 and preferably integral therewith, is a tubular socket '19, the axis of which is substantially parallel to the axisof the burner 10. Tubular socketlt) is tapped to receive a'set screw 20 for the purpose set forth hereafter. f r i 21 is a 'flange provided with a circular opening 22, which flange is fastened-to the furnace shell 15 by means of cap screws 23 and 24, respectively. 'At right angles to the face of the flange 21 is a round stud 25, the axis of which is substantially parallel tothe axis of the circular opening j 22- through 'so'cket'19 and stud 25. pe auon or my device isobvious. on .30

As mentioned su ra, it isof fth'e-i'itmost necessity that the alinem'ent' of the combustion chamber and the burner-be accurate,

that is, that their'fcenter lines coincide, as

otherwise the flame is not we'll' vdistributed within the combustion chamber andfmay even-excessively impinge on one side causing "unequal'wear, or it mayfleave a space on an other side permitting the drawing in of free air from the 'atmosphere; .This air may enter the "furnace unmixed width the carbon ele ments of the'fuel, and under-furnace .temperatures usually prevalent, attack the mate- I rial under .treatmentortits containers and V oxidize, burn, scale or otherwise injureor,

In my device, the burner and the combustion chamber cannot get out of alinement.
