PURPOSE:To provide a small-sized pulse burner of which operation is calm and of which composition is simple by a method wherein an ejector producing an effect of ejector is arranged at the downstream side of tail pipes of a plurality of pulse burners. CONSTITUTION:When a pulse burner 1 is ignited, combustion air 24 is passed through an air supplying part 18, air supplying decoupler 17 and an air check valve 7 under an operation of a blower fan and then it is supplied to the combustion chamber 3. Then, a pulse burner 2 is ignited. The ignited gas is flowed out of an outer cylinder 21 connected to the extremity ends of the tail pipes 6 into the discharging decoupler 22. At this time, the combustion gas flowed out of the inner cylinder 20 of the burner 1 shows a high speed and produces a negative pressure area in the outer cylinder 21. The combustion gas of the burner 2 is sucked by this negative pressure. In case that a different frequency is found in the burners 1 and 2 upon ignition, the burner 2 shows that the timing of ignition for the pulse type combustion gradually approaches to the timing of ignition of the burner 1 under an action of the sucking in the burner 1. That is, the pulse frequency of the burner 2 approaches to the pulse frequency of the burner 1, resulting in showing a synchronous combustion. |
