PURPOSE:To enable maintenance of stable pulse combustion through prevention of staying of water of combustion formation in a combustion exhaust gas path, by a method wherein a tail pipe line and a heat exchanger line are sloped downward in the direction of a decoupler, and a drain pipe for discharging water of combustion formation is connected to the decoupler. CONSTITUTION:The lines of a tail pipe 17 and a heat exchanger 19 are respectively sloped downward toward a decoupler 18, and a drain pipe 22 for discharging water of combustion formation is connected to the base of the decoupler 18. the air for combustion and fuel gas are mixed in a combustion chamber 11 to ignite and explode the mixture. Exhaust gas is exhausted to the tail pipe 17 side by means of an explosion pressure. Since the combustion chamber 11 is brought into a negative pressure state, the air for combustion and fuel gas are automatically fed in the combustion chamber 11, and they are automatically ignited by a combustion residual heat and are explosed. Water of combustion formation, produced when exhaust gas passes through the tail pipe 17, the heat exchanger 19, and an muffler 21, flows in the decoupler 18 and remains therein, resulting in prevention of worsening of combustion properties and of unstabilization of oscillation of pulsatory combustion. |
