Burner with flame ring stabilization chamber

Abstract

Gas burners on modern kitchen cooking appliances are subject to fluctuations caused by drafts, breezes, etc. These burners will require flame stabilization chambers or another suitable engineering solution to overcome this problem. This invention describes a flame stabilization chamber that is constructed exterior to the main burner chamber and covered by the burner cap. The flame stabilization chamber acts to prevent extinguishing of the flame due to a random draft or breeze, by providing additional captured flammable gas/air so as to maintain the flame.
