To all 20 7mm it may concern:
Be it known tl l, Jot-IN Earn, a subject of the King of Great Britain, and residing at 3-5) Church street, in the city of New York, in the State of New York, in the United States of America, have invented a new and useful Oil-l3urning-Furnace Front, of which the following is the specification.
The invention relates to oil burning furnace fronts as described in the present speciication and illustrated in the accompanyin drawings that form part of the same.
The invention consists essentially in the novel construction and arrangement of the air guiding walls or baffles, whereby the air in a forced draft system is directed into and distributed between the front and back plates of a furnace front in such a manner as to superheat it or maintain it at a comparatively high temperature until it reaches the flame.
The objects of the invention are to promote the combustion of the fuel. by means of air from which the chill has been thoroughly removed; to economize in the consumption fuel, and at the same time utilize fuel oils of comparatively low grade and yet obtain good results in steaming; to simplify a control of the draft of air forced in a furnace; to avoid complications in the parts and thereby furnish a front that will insure great; facility in repairs and replace ments; to facilitate the installation of furnace fronts particularly in marine engineer ing work, and consequently avoid losses from delays; andgenerally to provide a durable, efficient and serviceablefurnace front.
In the drawings, Figure l is a diagram matic view showing two batteries of furnaces, the blower and the air heater and the connections from the latter tothe furnace fronts.
F 2 is a cross sectional view through the heater and the furnace'front and showin the flue.
l ig. 3 is a sectional view showing a plan view of the air passages, heaters and furnace fronts in a battery of furnaces with the heaters shown as individual to the several fronts.
Fig. 4: is a vertical section of the form of the invention illustrated in Fig. 5.
Fig. 5 is an enlarged View showing in section a single furnace front with the peculiar form of air distributing passage.
Fig. -6 is a slight modification of the form of the invention illustrated in 5.
0 Fig. 7 is a vertical sectional view of the IOI'lIl illustrated in Fig. 6. v l Fig. 8 is still another modification of the invention showing another arrangement of the distributing walls.
Fig. 9 is a further modification of'the form shown in the aforesaid fl 'ures.
Like numerals of reference indicate corresponding parts in the several forms of the invention illustrated in the drawings.
Referring to the drawings, in the preferred form of the invention, the passages 1 lead from an air heater 2 to the air pocket between the front and-back plates 3 and 4:. The entrance 5 to the air pocket is preferably at one side of a furnace front and just within this entrance a valve 6 is installed, which controls the quantity received into said air pocket. I
The entrance 5 isreally the opening to aspiral passage 7 that resembles volute wheel, for the inner wall of the passage '4" terminates to form an inlet 8 to the center of the air pocket, and consequently to the air I cylinder 9 and oil burning equipment. which customarily comprises a burner 10 and cone deflector 11. The outer wall 12 of the spiral passage 7 joins the wall of the passagel, therefore the air is deflected by the inner wall when it reaches the end of the spiral passage 7 and c0 sequently. whirls around the air cylinder, thereby insuring an excellent distribution of air for the better consumption of fuel.
in Figs. 6 and 7, the front is formed with the customary flare .13 and the air shield 1 the latter terminating at the passe e wall 153, the other side 16 of the passage wall terminating at the flare 13 The passage wall, joins the deflecting wall 17, which curves around and forms a similar spiral passage 18 to the passage 7.
In Fig. 8 the air shields l9 and 20 are isolated at each side of the pocket and the central deflecting wall 21 projects upwardly from the flare 22. in this form of the invention, there aretwo air *iassages 23 and 24- from the air heaters and the outer walls of the said air passages 23 and 24: join the flare 22 at the upper flanges thereof and the inner inder until it is well distributed in the air pocket between the front and back plates.
In Fig. 9 there is only the one passage 27, as in the'earlier forms illustrated. The outer wall 28 of this passage joins the flare 29 at the upper flange thereof, and the inner wall and the opposite wall 30 of said passage 27 joins the air shield 31. The shield 81 extends between the front and back plates of the furnace around the upper end thereof to the vertical wall 31 and the latter joins the other upper flange of the flare 29.
The radially pointing deflecting walls 32 and 33 extend from the flare 29, while the inner deflecting wall 34 completes the passage effect. The inner wall 84 extends part way across the air pocket above the air cylinder 35 and downwardly at each side of said air cylinder and terminating slightly below said cylinder. Intermediate of the height of the vertical portions of said inner wall 84, the horizontal deflecting walls 36 extend inwardly.
The transverse section of the inner wall 3'} is formed with a central opening closed by the valves 37. It will be seen that in this form of the invention the same purpose is sought for and obtained, that is to say, thor-i oughly distributing the air in the air pocket between the front and back plates previous to delivering it to the flame, which is an excellent plan, because the temperature of the air is maintained and even heightened,
by its proximity to the firebox.
It may be stated, in the operation of this invention, referring particularly to the forms illustrated from 1 to 5, the air forced in by the blower illustrated to the heater or heaters flows down the several passages to the fronts of the furnaces and whirls around in the volute form of pocket and out through i the cone deflector and their cylinder to the flame. The air in thus making its passage must reach the flame at an even temperature and therefore there can be no chill and con scquently dampening effects of the flame from the forced draft system of air blowing in thereto, in fact all theair coming originally from the blower receives its final heating in the air pocket between the front and back plates of the furnaces and there becomes superheated to a temperature as near as possible to the heat of the firebox.
In the modifications shown, the operation is very much the same, with the difference that the course of the air is obstructed by diverse cross walls, which all tend to retain it long enough in the pocket to get a further heating before it reaches the flame.
Further modifications may be made in the arrangement of the Walls forming the as sages without departing from the spirit of the invention, and so long as such changes are within the scope of the claims for novelty following, the protection accorded shall not be invalidated.
What I claim is 1. In an oil burning furnace front of the forced draft system of furnaces and having front and back plates forming an air pocket therebetween, an air passage from a suitable air supply, one wall of said passage being an intermediate wall distancing said front and back plates and inclosing said air pocket, and a deflecting wall within said pocket as sociated with said outer wall in distributing the air throughout said pocket before reaching the flame.
2. In an oil burning furnace front of the forced draft system of furnaces and having front and back plates forming an air pocket therebetween, an air passage from a suitable air supply having one wall continuing and forming the inclosure for said air pocket and a distancing wall between said plates, and a deflecting wall forming an obstruction in the way of the outlet to the burner and consequently a distributer for the air from I said passage delivering it from many sides to the flame.
3. In an oil burning furnace front of the forced draft system of furnaces and having front and back plates forming an air pocket therebetween, an air passage from a suitable air supply having one wall continuing and forming the inclosure for said air pocket and a distancing wall between said plates, and another wall meeting the aforesaid wall and continuing to the interior of the pocket to spiralize the air passage around and to the air outlet to the flame.
l. In an oil burning furnace front of the forced draft system of furnaces and having front and back plates forming an air pocket therebetween, an air passage from a suitable air supply having one wall continuing and forming the inclosure. for said air pocket and a distancing wall between said plates, and an inner wall starting from the end of the aforesaid wall and extending clownwardly and in a circular path and terminating above the air cylinder and forming with said inclosing wall a spiral passage formed to produce a whirl of air around and about the outlet to the flame.
