PURPOSE:To improve an ignition performance at an ignition time by forming a cross section of a flow passage from a rectifying plate to a ceramic plate burner in a manner that it becomes narrower gradually, with providing a rectifying plate in the flow passage of a burner case. CONSTITUTION:To provide an uniform velocity distribution of a mixed gas flowing out from the ceramic plate burner 7, a cross section of a flow passage 8 from a rectifying plate 9 to a ceramic plate burner 7 is formed in a manner that it becomes narrower toward a top of the ceramic plate burner 7. Thereby, besides an uniform combustion is took place, a volume of the passage 8 can be reduced and an ignition performance at an ignition time improved, moreover, a generation of a bad smell can be reduced at an extinguishing time. |
