PURPOSE: A gas burner is provided to withstand an air turbulent flow comparatively well particularly when the inflow of burner fuel is small in the quantity. CONSTITUTION: A gas burner assembly for connection to a gas source comprises a burner body having a sidewall(16) and a main gas conduit. The burner body further includes a number of primary burner ports(32) disposed within the sidewall, each for supporting a respective main flame. Additionally, a main fuel chamber(24) is disposed within the burner body to provide fuel to the primary burner ports. A burner cap(22) is disposed atop the sidewall. A stability channel is disposed within an outer portion of the burner cap. The stability channel is positioned adjacent the primary burner ports to capture a supply of gas and hot products from the burner assembly to re-ignite the primary burner ports after flameout. The configuration creates a repository of fuel and combustion products during normal burner operation within the stability channel for re-igniting the primary burner ports after flameout, thereby reducing the sensitivity of the burner assembly to pressure disturbances, while allowing a symmetric appearance to be maintained.
