2 Claims.

My invention relates to improved method and means for burning a gas.

The object is to introduce or project a jet of gas from a source of supply, into a place of combustion where the same is mixed with air, ignited and burned, and to maintain the jet of uniform or constant cross-section and Volume, by initiating the jet at a point substantially in advance of and removed from the place of mixing ignition and combustion.

This object is attained by protecting the jet orifice from the radiant heat of combustion.

By this method the orifice, which initiates the jet, is sufiiciently protected from the heat of combustion, or radiant heat, to prevent the orifice from being clogged.

In accordance with the common practice, the combustible mixture of gas and air'is delivered through the orifice directly to a combustion space, so that the heat of combustion frequently causes accumulations around or in the orifice, which tend to clog or choke the same, as by coking,

sulphurization, or the like.

Referring to the drawing, which illustrates merely by way of example, suitable means for the embodiment of my invention;

Fig. 1 is a view in section showing the relation of the tip or orifice, the protecting channel or passage, the source of gas and the place of ignition and combustion,

Fig. 2 is a-fragmentary plan view.

Similar numerals refer to similar throughout the several views.

In the construction illustrated in Fig. .1, the body 5 is threaded into the wall 6, which separates the place of ignition and combustion I, from the chamber 8 containing the gas supply. The body 5 is provided with the passage or channel 9. Body 5 is also provided with the orifice I0, between the gas supply in chamber 8,'and the channel or passage 9.

The gas is projected through the orifice II], in the form of a jet l I, which passes entirely through parts the passage or channel 9, into the ignition and the combustion space I, where it is mixed with air..

The vent or orific I0 is screened or protected by the wall of the channel 9 from a large percentage of radiant heat of the furnace, since the angle of part of its longitudinal extension, into the chamber 8 containing the supply of gas. The result of this arrangement is that said body 5 is immersed in said comparatively cool gas. This serves further to reduce the temperature of said body 5, and thus protect the orifice. This arrangement permits the use of other than refractory or ceramic'material, such as lava, in constructing the body 5,

The relative dimensions of the body 5 may be varied to suit varying conditions. 1

The variations in the ratio between the orifice and the channel diameter, between the orifice and. the depth or length of channel or passage 9, and the depth of immersion in the gas, will vary depending upon the quality of the gas, as to moisture content, sulphurous compounds, and th temperature at which the furnace operates.

What I claim is:

1. In combination with a furnace combustion chamber and a fuel gas supply chamber, a gas burner tip comprising a chambered body open at one end and provided at the other end with a gas orifice, the open end of said body being seated in a supporting wall between the furnace combustion chamber and the gas supply chamber and delivering directly to said combustion chamber for mixing with air therein, the margin of the open end of said tip being approximate the inner surface of said supporting wall, the opposite end of the tip, which is provided with the orifice, being in communication with the gas supply, the said orifice being positioned at a point sufficiently remote from the place of combustion in the furnace chamber to secure the protection of the orifice by the walls of the chambered body from the heat of the furnace.

2. In combination with a furnacecombustion chamber and a fuel gas supply chamber, a gas burner tip comprising a chambered body open at one end and provided at the other end With a gas orifice, the open end of said body being seated in a supporting wall between the furnace combustion chamber and the gas supply chamber and delivering directly to said combustion chamber for mixing with air therein, the margin of the open end of said tip being approximate the inner surface of said supporting wall, the opposite end of the tip, which is provided with the orifice, being in communication with the gas supply, the said orifice being positioned at a point sufiiciently remote from the place of combustion in the furnace chamber to secure the protection of the orifice by the walls of the chambered body from the heat of the furnace, and the'greater extent of said tip being immersed in the gas supply and partaking of its temperature,
