PURPOSE:To decrease a lifting combustion and to enlarge the width of combustion so that a good burning state can be attained, by disposing burner ports on the circumferencial wall of a burner body, giving each of them the shape of T consisting of a circumferencial slit portion and a horizontal slit portion. CONSTITUTION:Combustion flames of fuel-air mixture, injected from a burner port 12 of a burner body 2, form a combustion of high calorific capacity and large combustion rate at the T-shaped crossing portion 12c of a circumferencial slit portion 12a and a horizontal slit portion 12b, and a combustion of relatively low carolific capacity and small combustion rate in the rest of the burner port, namely, forming a trigonal-pyramid-shaped flame in a reversed triangular shape, with the flame ends at top of the circumferencial slit 12a, at both ends of the horizontal slit and at the crossing portion 12c respectively, constituting apex of said pyramid. The T-shaped burner ports 12 and small round holes 13, interacting each other, improve their flame-holding condition, making more difficult the occurrence of the lifting combustion, expanding the width of combustion, thus resulting in a stable combustion, limiting red heating of the multiholed cylinder.
