Abstract
Abstract A flare burner of the ground flare type for incinerating waste combustible gas from refineries and the like is disclosed, for use in populated areas, which has a plurality of waste gas burner heads for simultaneous operation at the same level, which may be utilized as a ground flare or which may, in a modified form, be elevated and provided with a bottom heat shield, which can have additional combustible liquid waste burners in one or more side walls, the flare burner having a combustion chamber with an improved panel construction and a fence of the knock out type to minimize wind effects and to provide an acoustical barrier so that noise transmission horizontally from the lower air inlets is greatly reduced.
