Abstract

A gas burner, of the type that receives two separate feeds that allow the formation of a central flame and, at will, another concentric annular flame, and that have an upper part that consists of a ring that adapts leaving multiple steps in its outer periphery to an annular channel that recites the gaseous mixture, and of another central part joined to said ring by radial ribs and which takes the form of a disc or cap that covers peripheral passages leaving the mouth of a vertical cylindrical chamber, at the that the gaseous mixture also arrives, characterized in that said upper part has, along one of the ribs, a radial conduit that communicates said central cylindrical chamber with the outer periphery of the ring so that, upon closing the feeding to the annular channel, but keeping the central flame, a flame remains lit in the terminal opening of said duct, fed from the chamber, whose flame it allows the spontaneous ignition of the annular ring or flame when the corresponding communication is reestablished, leaving the gaseous mixture through the peripheral passages of said crown.
