Description
Feb. 8, 1949. M. w. HoENsHELL GAS BURNER CONSTRUCTION Filed Aug. 5, 1946 INVENToR.
kM. W. Hafen sb e BMW ATTORNEY Patented Feb. 8, 1949 UNITED STATES PATENT oFFlcE 2 Claims.
The present invention relates to combustion appliances, and particularly to fuel burners for furnace apparatus designed for the combustion of gaseous fuel, and Vaims to devise an improved construction for the more eflicient combustion of such fuel by improving the method of supply of the combustible mixture to the burner zone.
Accordingly, I have devised an improved burner construction for regulating the supply of the gas and air ow to the burner zone in such a way 'as to maintain a well dened path or course of movement of the mixture and at ,the same time avoid any conflict between the incoming air and gas iiow and the outgoing fuel mixture which is being supplied to the fire chamber of the furnace.
To this end I provide a burner construction comprising a cylindrical housing member to which the combustible mixture is fed in tangential relation for producing a circular movement of the fuel mixture about a cylindrical block of refractory material located centrally of said housing member, and an improved structural means operating to conne the flow of the out-v Figure 1 is a vertical sectional view illustrating a burner construction equipped with the-'improvements of the present invention, said view being a section taken on the line I-I of Figure 2;
Figure 2 is a horizontal sectional view, representing a section taken on the line 2-2 of Figure l; and l. Figure 3 is a transverse sectional view (with portions broken away), representing a section taken on the line 3-3 of Figure 2. -V
Referring now to the accompanying drawing detail, this shows the burner -appliance as comprising a, metallic boxing member having a rectangular portion I2 for projection through the front of the furnace ashpit, and a cylindrical burner housing portion I4 which is open at the top as indicated at I5, while both the portions I2 i and I4 of the boxing are provided with a. continuous bottom I6 designed to rest upon the oor of the furnace Iashpit.
The boxing portion I2 communicates with the burner housing portion I4 by way of a reduced neck portion I 8 so arranged as to provide an outlet passage 20 from the boxing I2 communicating in approximately tangential relation `to the housing I4 and thereby correspondingly directing the ow of air and gas into the annular space 2| surrounding a refractory block structure II located centrally within said housing portion I4. Preferably the bottom I6 is formedwith a spur 22 or the like engaging in a corresponding recess 23 of the refractory block structure in position for locating the latter in substantially central relation to the space enclosed by the housing I4.
In burners of this type the fuel supply is admitted entirely by way of the passage through the boxing portion I2, the main flow of gas being supplied by a pipe 25 terminating in a nozzle 26 at the aforesaid passage 20. A similar gas supply pipe 21 terminates adjacent to said vnozzle 26 for maintaining a pilot flame adjacent to the tip of the nozzle, and a proper supply of air is of course admitted to the housing portion I2 in the conventional manner as provided for in the apparatus set forth in Patent No. 2,027,159, dated January 7, 1936.
The upper end of the refractory block structure II may be formed with an outwardly pro'- jecting margin I3 overlying the annular space 2| ,v the outer face of which margin slopes upwardly and thereby provides a baille for deflecting the flame outwardly and at the same time permitting upward movement thereof in the direction of the interior surface of the walls of the furnace re chamber. Y
For carrying out the purposes of the present invention I make provision for further controlling of the movement of the combustible'gmixture by introducing an additional block element 30, of fire brick or like refractory material and of substantially quadrantal shape, into that portion of the annular space 2| which completes the circuit of the combustible mixture withinthe housing portion I4, around the block structure II. This block element 30 has a flat base portion 32 for resting upon the bottom I6 of the housing I4,
and the upper face 34 of the block is of helicalV contour and extends from the level of said bottom I6 (i. e., from the bottom of the annular space 2|) to approximately the same elevation asthe top ot the passage 20 representing the entrance opening of said space 2| within the housing I4.
By this 'means the now of the entire combustible mixture of air and gas is directed upward prior toits completing a circuit around the refractory block structure and finally discharged above the level of the incoming gas and air from the housing portion I2. This has the important advantage ci preventing any interference with the movement o the incoming air and gas supply, and also blocks any tendency of the latter from following any other course than the intended or forward tangential course around the refractory block as indicated by the arrows in Figure 2.
The operation of the burner is substantially as curved and sloping upper face acting to direct the set forth in the aforesaid patent, as regards pro-I intermingling of the gas and air, as well as uniform distribution of the combustible mixture all around the burner and even flame distribution around the base of the furnace re chamber; but with this increased importantadvantage .that the provision of the helical block member 33 efectively eliminates any possible chance of interference between the flow of the incoming gas and air flow from the housing i2 with the combustible mixture in its course around the annular space 2i, since by the improved construction the paths of movement of these two ilows are thus kept den nitely separated until the dual combustible mixture is discharged at a level entirely above the opening by way of which the incoming gas and air Vare admitted to said annular space 2l. `By means oi the foregoing improvement the operation of the burner appliance is very greatly increased in its eiiiciency, and at a relativelyvery small expense for theY addition of the simple accessory feature necessary for tlius altering or modifying the basic structural combination of the burner` illustrated in the patent referred to.
-While I have illustrated and described a very simple expedient for the carrying out of the pro-vv posed features oi improvement, I desire .tol be understood as reserving the right to make such changes or modifications as may fairly fall within the spirit and scopev of my invention asdened f Y course of the fuel mixture to a level entirely above that of the flow through said fuel supply passage,
said helical block terminating in an end face in the sametang'ential relation to said cylindrical bloclras said fuel supply passage.

A fuel burner construction comprising, a cylindrical housing member open at its upper end, a cylindrical refractorybloeitV mounted centrally within Sad housing member and in ,spaced relation to the inner w21-1,1 thereof to provide an an: nular space around said block, the lower DQltion of said housing member being provided with a fuel supply passage for supplying a. combustible fuel mixture to said annular space and communicatme therewith anancle Substantially tangential to the Acylindrical face of said block, and a helical refractory block in the space traversed by said iuel mixture as it .completes its circuit thrcugh'said `annular space and provided With a Curved and Ysloping upper face to .direct the course of the fuel mixture to a level entirely abovethat of the flow through said fuel passage, said helical bloclterminating in a vertical end face extending in the ysaine tangential relation to said cylindrical block as said fuel supply passage and forrnmg the inner kside Wall of said passage.
