されるようになっている。At startup, air is supplied from the air supply pipe into the mixing chamber by the blower, which is driven only during startup, and fuel is supplied from the fuel supply pipe via the fuel flapper valve and mixed within the mixing chamber. A mixture of air and fuel is ignited by a spark plug, causing explosive combustion within a combustion chamber. In this case, the air flapper valve and fuel flapper valve connected to the air supply pipe are each closed by the explosion pressure in the combustion chamber, and the combustion gas in the combustion chamber is discharged from the tail pipe connected to the combustion chamber. It is designed to be exhausted to the outside via a large coupler and an exhaust pipe. Also, when the pressure inside the combustion chamber decreases due to the exhaust of combustion gas, both the air and fuel flamper valves are opened, respectively, and air and fuel are supplied again, and the air and fuel mixed in the mixing chamber are mixed. The gas is ignited by the high-temperature residual gas remaining in the combustion chamber or by contact with the high-temperature combustion chamber wall surface, etc., and explosive combustion occurs again. From then on, the same operation causes explosive combustion within the combustion chamber to occur in pulses. is repeated. In addition, when starting, send I! When one unit is driven, combustion air is supplied from the air supply pipe to the pulse burner through the air flapper valve, and after startup, the drive of the ms is stopped and the combustion gas is Combustion air is drawn into the pulse burner from the air supply pipe by the negative pressure within the combustion chamber created during exhaust.

があった。Incidentally, conventionally, it has been considered to connect a plurality of pulse burners having the above configuration to form a combustion apparatus main body having a large heat capacity. In this case, it may be possible to connect the air supply pipes of multiple pulse burners to a common air supply source to create a common air supply system.
When the drive of III is stopped and combustion air is drawn into the pulse burner from the air supply pipe due to the negative pressure in the combustion chamber, differences in the intake pressure of each pulse burner tend to occur due to differences in combustion heat load, etc. When a difference occurs in the intake pressures of the pulse burners, a large amount of combustion air is taken in by the pulse burner with a high intake pressure, and there is a risk that the pulse burners with a lower intake pressure will be insufficiently supplied with combustion air. Therefore, there have been problems such as pulse oscillation becoming unstable after starting, or pulse burners having stopped pulse oscillation.
