Application June 9, 1933, Serial No. 675,019

3 Claims.

My invention relates to gas burners.

The object of my invention is to provide a gas burner of a type to promote effective combustion of a mixture of inflammable gas and air. A further object of my invention is to provide a gas burner of the kind described which embodies the use of concentric bowls or annular deflectors and a core centrally positioned over a burner of a kind now in common use, and a perforated dome.

A still further object of my invention is to provide a burner of the kind described in which passages are arranged to cause an impingement of the flow of an inflammable mixture in order to approach a more complete combustion.

These and other objects will hereinafter be more fully explained:

Referring to the drawing in which like characters apply to like parts in the different, views:

Fig. 1 is a plan view of the burner, the perforated dome not shown.

Fig. 2 is an elevation of the burner with parts broken away andparts shown in section for the purpose of illustration.

Fig. 3 is a perspective view of one of the annular deflectors.

A burner of a conventional type now in common use, comprising a hollow cylindrical body 1, having perforations or jets 2 on its upper surface, a mixing chamber 3, and a valve 4 is connected to a supply of inflammable gas at A.

The core 5 and the annular deflectors 6, 7, and 8 respectively are concentrically positioned on the burner as shown. The core 5 is shaped to flare at the points B and C.on its periphery. The deflector 6 is formed to flare at D and E on its outer, and at Fon its inner, periphery. The deflector 7 is formed to flare at G on its outer, and at H on its inner, periphery. The deflector 8, which in the instance illustrated is the outer deflector, is formed to flare at I on its inner periphery. A dome 9, perforated at J is positioned as a top for the burner and rests on the deflector 8 at K. Vents L are provided at the lower extremity. of each of the rings.

The flared portions onthe various deflectors and on the core 5 are positioned to provide a tortuous path between the walls of the deflectors and between the inner deflector and core, for the buming gaseous mixture in the manner indicated by the arrows; Impingement of the mixture against the surfaces of the deflectors occurs at each flared portion during its upward movement between the deflectors and between the inner deflector and core, and finally against the dome before escaping through the perforations J. v

The primary addition of air is accomplished at M and the secondary addition of air occurs through the vents L.

The deflectors and core may be composed of any material capable of withstanding high temperatures; however a refractory material is preferable.

In operation the burner described functions to provide a very effective combustion of inflammable gaseous mixtures, under comparatively low initial pressures. Such modifications may be employed as lie within the scope of the appended claims and what I claim as new and desire to secure by Letters Patent is:

1. In a burner of the kind described, in combination with a perforated cylindrical discharge device, a plurality of annular deflectors, flared portions on the walls of the deflectors, a core, flared portions on the core, the said core and deflectors concentrically disposed on the discharge device and arranged to receive a gaseous mixture therefrom.

2. In a burner of the kind described, a discharge device for a gaseous mixture, a plurality of bowl shaped annular deflectors, 'said deflectors concentrically disposed, flared portions on the surfaces of the deflectors, a core, said core positioned concentric to the deflectors, flared portions on the core, a dome having perforations, the said deflectors positioned on the'discharge device to re- .ceive the gaseous mixture and the said dome positioned above the deflectors.

3., In a burner of the kind described, a discharge device for a gaseous mixture, a plurality of bowl shaped annular deflectors, flared portions on the surfaces of thedeflectors, a core, flared portions on the core, the said core and deflectors concentrically positioned on the discharge device and arranged to receive a gaseous mixture therefrom.
