<p>A gas burner is disclosed which includes a fire cover, a flame spraying unit, a base and a gas supply unit. There are a central flame ring, an inner flame ring, and an outer flame ring provided on said flame spraying unit. A central gas mixing chamber is formed in the central flame ring while a central gas mixing tube is provided in said central gas mixing chamber. At least three periphery gas mixing chambers distributed uniformly are formed between said inner flame ring and said outer flame ring, and a periphery gas mixing tube is provided in the central section of each periphery gas mixing chamber. On said base there are provided a central nozzle chamber corresponding to said central gas mixing tube and a periphery nozzle chamber corresponding to said periphery gas mixing tube. On said gas supply unit there are provided a central nozzle corresponding to said central nozzle chamber and a periphery nozzle corresponding to said periphery nozzle chamber. The gas burner according to the invention not only has simple structure and can be machined easily, but also can form uniform flame and large flame in the middle, with three flame rings being used simultaneously or the central flame ring being used alone.</p> |
