ABSTRACT A burner assembly is disclosed for the smokeless burning of low calorific value gases, or diluted hydrocarbon gases, which comprises a plural- ity 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 hub of the head, arranged in equally-spaced array, each of the arms having a plurality of ports in the top surface, near the end of the arm. These ports are of selected size and selected angle of their axes, which are tilted inwardly towards the central axis of the burner head. 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 which is positioned beneath the arms to close off the vertical flow to the spaces 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 cylindri- cal tube against which the gas jets, which can be sonic, impinge, so that the jets are diffused throughout the entire volume between the arms and above the arms. Air diffuses inwardly through the surrounding perforated wall to mix quietly with the gas so as to maintain a continuous combustion, with sufficient air to prevent the formation of smoke.
