Apparatus for burning combustible gases at very low pressure, in combination with a combustion chamber having an opening through one wall. The burner system comprises a burner tube for supplying the low pressure gas, comprising a tube of selected diameter and length, with an annular flange extending inwardly at the end inserted into the opening in the wall. A steam tube of smaller diameter than the burner tube, is mounted axially inside of the burner tube, and has a closed end in the plane of the inwardly extending flange. A plurality of orifices are drilled through the closed end of the steam tube at a selected angle to the axis, whereby when steam is supplied to the steam tube, at 5#gauge or more, high velocity jets of steam will flow outwardly through the orifices along the surface of a cone, and will aspirate into the steam streams the low pressure gas, which will be mixed with the steam, and will flow as a conical wall of steam and gas. This high velocity flow will aspirate air into the steam-gas streams for provision of air for burning the gas fuel completely.

Apparatus for burning very low pressure gas which, by its pressure and velocity, is unable to aspirate air sufficient for combustion in combination with a combustion chamber, having an opening through one wall, and a source of very low pressure gas, comprising a burner axially positioned into said opening, said burner comprising; (a) a burner tube into which the low pressure gas is supplied, the tube of selected diameter and length, and having an annular inwardly extending flange at the flame end of selected radial width, said flange beveled around its inside upstream edge, said burner tube closed at the other end, (b) a tube positioned axially inside said burner tube, said tube passing through said closed end into said burner tube and terminating with a closed end below the top of said annular flange said end machined with its outer surface conical, (c) a plurality of orifices or ports drilled into and perpendicular to said conical surface of said tube, (d) means supplying steam, at pressure of at least 5 psig, into said tube, whereby high velocity jets of steam issuing from said orifices will flow in the form of a conical wall through the annular opening in said wall into said combustion chamber, whereby said low pressure gas will turbulently mix and flow with said conical wall of steam, and thence through said opening into said combustion chamber, and whereby said flow of steam and gas will aspirate combustion air which surrounds said burner tube into said opening to mix with said steam and gas for burning.
