PURPOSE:To stabilize the flame current detection of a burner by providing a number of burner ports on the periphery wall of the burner body and forming auxiliary burner ports at the lower parts of the burner ports placed in opposition to a frame rod, in the burner of a space heater or the like. CONSTITUTION:A plurality or auxiliary burner ports 26 are provided at the lower parts of burner ports 17 that are placed at parts provided with a frame rod 25. Thus, the quantity of flame in the vicinity of the frame rod 25 increases, and a flame current of the frame rod increases. Accordingly, even when the fitting position of the frame rod 25 is slightly irregular, it is possible to detect the stable flame current, and hence to widen the flame detection range of the frame rod 25. |
