The invention pertains to a burner assembly for industrial purposes for producing a generally fiat fan-shaped flame from the combustion of liquid fuel and gaseous fuel and developing as much as four and one-half million British thermal units per hour. A wall of a furnace within which heat in such quantities is to be produced is in dicated at 10. An elongated rectangular shaped opening 1 is provided in the wall 10 for accommodating an elongated generally rectangular shaped refractory member 12. The member 12 may be formed of any suitable ceramic material and is adapted to fit within the rectangular shaped opening 11. The downstream end portions of the refractory member 12 may be flush with the inner surface of the wall It The upstream end portions of the refractory member 12 may also be flush with the exterior of the wall it).
The refractory member includes a top wall 26 and a bottom wall 17. End walls 13 and 19 join the top and bottom walls 16 and 17 and the refractory member 12 may be formed as a unitary ceramic body. The end walls 18 and 19 are relatively thick as will be appreciated upon a consideration of FIG. 2. An angular face 21 is formed on the downstream portion of the end wall 1%. The angular face 21 flares from the center line of the burner assembly or the axis of the liquid fuel burner. A simlar angular face 22 is provided upon the downstream portion of the end wall 19 which flares from the center line at the burner assembly. A rectangular shaped opening 24 is provided through the refractory member.
A housing as is provided at the exterior of the wall 15 and may be secured thereto in any suitable manner to span the opening 2d provided through the refractory member 12 and to provide means for supporting the burner heads thereon and to support air registers for controlling quantitles of air admitted to the presence of the burner head for liquid fuel and to the furnace chamber through the opening 2 in the refractory member. The front wall 27 of the houisng 2-6 is provided with an opening 23 which is encased by a stationary air register member 29 of a hernispherical shape having openings 31 therein. A hemispherical shaped sleeve 32 is mounted for rotation on the stationary member 29 and openings 33 may be brought into registration or partial registration with the openings 31. The stationary member 29 of the air control device is supported by the front wall 27 of the housing 26.
A nozzle 3% is arranged within the housing 2.) and is supplied with liquid fuel and an atomizing medium through a supply pipe 37. A guide tube 38 extends through the stationary air register member 2% and provides support for the pipe 37 and the nozzle 36. A shroud 51 is supported by the front wall 27 of the housing 25. The shroud 41 has a top wall 43 and a bottom wa l 44 which are in substantial parallel relationship. The shroud includes angular side walls 46 and 47 which diverge from each other in proceeding downstream of the burner assembly as best shown in FIG. 2. The shroud extends into the opening 2 in the refractory member 12. The inner faces of the side walls 46 and 47 are substantially parallel with respect to the angular faces 21 and 22 formed on the end Walls of the refractory member.
The air register assembly formed of the elements 29 and 32 provides for the control of the volume of air admitted to the presence of the burner nozzle 36. This air register and the openings 31 and 33 therein are such that only limited quantities of air may be admitted to the upstream end of the shroud 41 to permit initial buming of the liquid fuel before additional quantities of air are allowed to move into the presence of the burning liquid fuel. Such an arrangement develops sufiicient heat within the shroud 41 to provide for continued stable burning of the liquid fuel.
The top Wall 51 of the housing 26 is provided with openings 52 and the bottom wall 53 is provided with openings 54. A slidable door 56 mounted under the top wall 51 may be moved transversely of the assembly by mean of a handle 57. The door 56 is provided With apertures which may be brought into registration or partial registration with the openings 52. A similar slidab le door 61 is provided overlying the bottom wall 53; and
is manipulated by a handle 62 to control the admission of air through the bottom wall of the housing 26.
The shroud 41 is spaced from the top and bottom walls of the refractory member 12 and from the side walls 15; and 19 so that the generally rectangular shaped opennaceward. The topwall 16 and the bottom wall 17.
may be arcuate shaped as indicated at 66 (FIG. 6) to facilitate movement of the air through the opening 24.
The assembly includes two burner heads 67 and 68 for the gaseous fuel. The burner head 67 is mounted in a recess 71 (FIG. 3) provided in the top wall 16 of the refractory member. The burner head 68 is mounted in a similar recess 72 formed in the bottom wall 17 of the refractory member. A gaseous fuel mixture is supplied through a conduit 7-6 and conduits 77 and 78 which extend through openings in the wa1l'27 of. the housing 26 and into operative association with the burner heads 67 and 68.
The burner head 67 is provided with a plurality of main discharge ports 81 which may be arranged in a row as shown in FIG. 3. The burner head 68 is provided with a similar group of discharge ports 82. A smaller number of discharge ports 8.3 are provided in' the burner.
The nozzle 36 for the liquid fuel is provided with discharge port 8-6 arranged to project a relatively thin fan-shaped pattern and the ports in the nozzle 36 desirably flare as shown in FIG. 2. The liquid fuel discharged through the ports 86 provides a relatively thin fan-shaped flame. Controlled and limited quantities of air admitted through the opening 28 provide stable burningof the liquid fuel to be attained' before there is any chilling of the burning liquid fuel by additional air which enters through the rectangular opening 24 in the ceramic member 12 downstream of the shroud 41.
If there is simultaneou operation of the burners for both types of fuels fuel streams issuing through the discharge ports 81 and 82 meet each other alongthe plane of the burning liquid fuel and the resulting flamerepresenting a combination of the burning gaseous fuel and v the liquid fuel provides a relatively thin fan-shaped flame.
The gaseous fuel 4i r The quantity of air downstream of the shroud 41 may readily be controlled by'the positioning of the doors 56 and 61.
While the invention has been described with reference to a particular organization of elements it will be appreciated that changes may be made in the components modifications and others may be made Without departing along with alterations inthe overall assembly. Such from the spirit and scope of the invention as set forth in ,refractory member having top and bottom walls and end walls forming'an opening therethrough, said jopening being generally'rectangularly shaped in cross section, faces on the end walls of said'refr'actorymember flaring from each other in proceeding to one end of the refractory member and defining side faces of said opening, a shroud sup- "ported within said opening having top and bottom walls, walls on said shroud diverging from each other and substantially parallelto said faces, said shroud having an upstream end, a liquid fuel burner tip within saidshroud, means associated with the fuel burner tip for developing a thin fan-shaped flame within the shroud and with the flame projecting therefrom into said refractory member,
