ABSTRACT:
A burner assembly for use in a gas burning fireplace for producing flame patterns simulating flame patterns produced by real burning wood, and a method for producing such flame patterns. A preferably cylindrical bluff body is placed into the gas flow path from a supply line dividing the flow into a first and a second flow and generating Karman vortices within each flow. The vortices between the two flows are staggered. Each flow enters into a burner and exits through the burner ports where it is ignited to produce a flame pattern. The vortices create a rotating turbulence within each flow such that each flow has relatively steady flow portions alternating with turbulent rotating portions. This variance in the flow results in flames that have varying intensity, as well as color, and produces flame patterns simulating those produced by real burning wood.
