ABSTRACT:
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.
