Abstract
A burner assembly for the smokeless flare burning of low calorific value gases, or diluted hydrocarbon gases, which comprises a plurality of separate burner heads arranged in a horizontal array, each of the burner heads being mounted on top of a vertical pipe through which the low calorific gases are supplied. A plurality of hollow radial arms are inserted into the wall of the head, arranged in equally-spaced array, each of the arms having a plurality of ports in the top surfaces, near the ends of the arms. These ports are of selected size and selected angle of their axes, which are tilted inwardly towards the central axis of the burner heads. Additionally, there is between each pair of arms at least one port drilled downwardly from the inside of the burner head, at a selected angle, so that jets of gas will impinge downwardly on an annular plate positioned beneath the arms, to close off the vertical flow to the space between the arms. The arms are surrounded by a shallow cylindrical wall which is perforated in a selected uniform pattern over its entire surface. Over each of the arms is a cylindrical tube against which the gas jets, which can be sonic, impinge, so that the jets are…
