Abstract:
A combustion apparatus comprising:a burner port assembly comprising an elongated first array of main burner ports for jetting and burning a fuel gas mixture of a concentration to make main flames, the combustion apparatus further comprising at least one second arrays of auxiliary burner ports for jetting and burning a further fuel gas mixture of a different concentration to make auxiliary flames; the second arrays of said auxiliary burner ports being extended along the first array of said main burner ports, and the burner port assembly being constructed using inner and outer wall segments together with outermost bands; the inner and outer segments being corrugated to define between them openings serving as the main burner ports; and the one of said outer segments facing the corresponding one of said outermost bands so as to define between them collateral burner ports, wherein a still further gas mixture to be jetted from and burnt at the collateral burner ports is either of the same concentration as that for the auxiliary burner ports or of a medium concentration between said respective concentrations for the main and auxiliary burner ports.
