Abstract
A method and apparatus for flaring a gas stream such as the gas mixtures formed in landfills while retarding the backward propagation of flame thereto are provided. The method comprises conducting the gas stream to a burner structure having a plurality of flow passages therein configured such that the gas stream can flow through the passages, but the backward propagation of flame therethrough is retarded; flowing the gas stream through the flow passages of the burner whereby the gas stream is jetted therefrom and initially mixed with air; igniting the gas stream; and mixing the ignited gas stream with additional air by confining the jetted and ignited gas mixture within a stack configured to allow the admission of air around the burner structure and to discharge products of combustion into the atmosphere.
