4 Claims. (01. 158-7) the more efncient combustion of such fuel by improving the method of supply of the combustible mixture to the burner zone.
Accordingly, I have devised a construction and arrangement whereby the gas and air flow is supplied to the burner zone in such a manner as to produce a turbulent movement of the combustible mixture about the axis of the burner proper, for
insuring thorough intermingling of the fuelingredients as well as an effective distribution of the combustion action around the fire chamber.
To this end I provide a burner construction comprising a cylindrical housing member to which the combustible mixture is fed in a tangential relation for producing a circular movement of the fuel about a cylindrical block of refractory material located centrally of said housing member, the structure of said block being designed to promote the most effective distribution of the flame action throughout the combustion zone'at the top of the block and housing member.
with the foregoing general objects in view, the invention will now be described by reference to the accompanying drawing, illustrating a suitable and practical construction for the eflicient practice of the invention, after which those features and combinations deemed to be novel will be particularly set forth and claimed.
In the drawing- Figure 1 is a front elevation illustrating a furnace equipped with a burner embodying the preaent invention;
Figure 2 is a horizontal sectional view, representing a section taken on the line 2-2 of Fig-' ure 1;
Figure 3 is an enlarged vertical sectional view as indicated by the section line 3-4 of Figure 2;
Figures 4, 5 and 6 are sectional views as indicated by the section lines 4-4, H and M, respectively, of Figure 3; and
Figure '7 is a detail section illustrating a modifled form of refractory block member.
Referring now to the drawing in detail, this shows the improved burner appliance as installed in the ash pit I of an ordinary type of warm air furnace 9, the two principal elements of my construction comprising a metal boxing member designated generally by the reference numeral II, and a refractory block ii. The boxing member comprises a rectangular portion I! projecting through the front opening it of the ash pit I, and a cylindrical burner housing portion it which is open at the top as indicated at ll. while both portions l2 and ll of the boxing are provided with a continuous upon the floor of the ash pit. The boxing portion l2 communicates with the burner housing It by way of a reduced neck portion is so arranged as to provide an outlet e from the boxing it, communicating approximately tangential- 1o ly with the housing ll, thereby correspondingly directing the iiow of airand gas into the annular space 2| surrounding the block ll, asindicated by the arrows in Figure 4. Preferably, the bottom I! is formed with a spur "or the like, en- 15 gaging ina corresponding recess 28 of the block Ii, in position for locating the latter in correct central relation to the space enclosed by the housing it.
In assembling the appliance in operating rela- 20 tion, the fire grate and ash pit door of the furnace are removed, andthe opening 33 sealed by means of a suitable cover plate 24 having an openin accommodatingthe projecting portion of the boxing it, so that the'fuel supply is admitted entirely 25 by way of the passage through said boxing. The main flow of gas. is admitted through the pipe line 25 extendingthrough the side of the boxing and terminating in a suitable nozzle 26 at the passage A similar gas pipe 21 is also connected with the pipe 25 and terminates adjacent to said nozzle 28 for maintaining a pilot flame adlacent to the tip of the nozzle 20. The outer end of the boxing is equipped with a casting it fitted with a swinging damper plate 30 having a spring con- 36 nection 2i with an operating arm 32, as illustrated in Figures 1 to 3.
A pressure controlled valve 84 is provided in the gas line 25. and the usual control devices for thermostatic operation of the furnace are also 40 provided, such as the combination gas-valve and damper operating motor 3! and safety-pilot switch II, having the electric connections 31 with a thermostat (not shown), the operating features of which are all common and well known.
The upper portion of the burner housing it and top of the block II project into the lower portion of the fire bowl of the furnace from which the grating has been removed, and preferablyso the upper end of the block II is formed with an outwardly projecting margin It overlying the space II, the outer face of which margin ll slopes upwardly as represented in Figures 3 and 5, thus providing a baiiie for deflecting the flame bottom I. designed to rest 5' 2 ace-7,159
outwardly and at the same time permitting upward movement thereof in the direction of the interior surface of the walls of the fire bowl.
A slight modification of this feature of the construction is shown in Figure 'I, where the top marginal flange of the refractory block is omitted, while the block ii itself is made of downwardly tapered or sloping design, tending to direct-the flame both outwardly and upwardly in the direction of the interior face of the fire bowl.
In the operation of the apparatus it will be understood that the pilot flame is of course intended to burn constantly, and the control devices produce intermittent operation of the damper and of the gas flow through the pipe 25 to the nozzle 26, in the usual manner, in response to the thermostat-control device. The flow of air through the boxing l2 and thence through the restricted passage 20, where it is combined with a flow of gas from the nozzle 26, and the later combined flow of gas and air through the space 2! around the block I i are indicated by the series of arrows in Figure 4. The combustible mixture is ignited by the pilot flame adjacent to the nozzle 28, and the energy of the gas flow is suificient to produce a circular movement of the combustible mixture around the block I i, which action is of course further promoted as soon as the conditions of proper draft are established byv the heating up of the burner. This produces a vigorous turbulent condition within the space 2!, resulting in an intimate intermingling of the gas and air, as well as uniform distribution of the fuel supply all around the burner, and also an even flame distribution-around the base of the fire chamber. A state of combustion is established which is of maximum efliciency, as regards.
developing an intense heat-producing action which operates uniformly within and all around the fire bowl.
It will therefore be apparent that I have produced a thoroughly practical as well highly em cient construction for carrying out the aforesaid objects of my invention, and while I have illustrated and described what I now regard as the preferred form of construction for this purpose, it will of course be obvious that minor changes and modifications may be made without departing from the spirit and principle of the invention,
such as variations in the size or contour of the refractory block, or in the number of the gas nozzles 26; I therefore desire to be understood as reserving the right to make whatever changes or modifications may fairly fall within the scope of the appended claims.
Having thus described the invention, what I claim and desire to secure by Letters Patent is:
