Generally, a pulse burner has an air supply pipe and a fuel supply pipe connected to a mixing chamber connected to a combustion chamber. At startup, air is supplied from the air supply pipe into the mixing chamber by driving the blower, which is driven only at startup, and fuel is supplied from the fuel supply pipe via the fuel flapper valve, and the air is mixed in the mixing chamber. The mixture of fuel and fuel is ignited by a spark plug and exploded and burned in the fuel 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. Furthermore, when the pressure inside the combustion chamber decreases due to the exhaust of combustion gas, both the air and fuel flapper valves are opened, respectively, and air and fuel are supplied again, and the air and fuel mixed in the mixing chamber are The air-fuel mixture 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. Explosions and combustion are now repeated in pulses. During startup, the blower is driven to supply combustion air from the air supply pipe to the valve burner through the air flapper valve, and after startup, the blower 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.

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, but in this case, the drive of the blower is stopped after starting and the combustion When combustion air is drawn into the pulse burner from the air supply pipe due to negative pressure in the room, differences in the intake pressure of the pulse burners tend to occur due to differences in combustion heat load, etc. When a difference occurs in the intake pressures, a large amount of combustion air is taken in by the pulse burner with the higher intake pressure, and there is a risk that the pulse burner with the lower intake pressure will be insufficiently supplied with combustion air. As a result, there have been problems such as pulse oscillation becoming unstable after starting or pulse oscillation being stopped in some pulse burners.

定に行うことができる。 What is characteristic here is that this embodiment uses a fluid diode instead of a flapper valve on the air supply side. When flapper valves are used as in the past, the timing at which each valve opens is shifted due to the difference in the intake pressure of each pulse burner 2a to 2c, resulting in a large difference in the supply amount. On the other hand, when the fluid diode 7 is used, each pulse burner 2a
Although there is a slight difference in the supply amount due to the difference in intake pressure of ~2c, since the fluid diode is always open in the air supply direction, the difference in the supply amount is much greater than when using a flapper valve. It becomes small. Furthermore, by constantly driving the blower 10, in combination with the use of the fluid diode 7, it is possible to reliably prevent insufficient air supply to the pulse burner with low intake pressure. Therefore, the plurality of pulse burners 2a to 2c can stably oscillate.

For example, in the above embodiment, the fluid diode 7 is provided only on each air supply pipe 5 side, but the fluid diode 7 is also provided on each fuel supply pipe 6 side instead of the fuel flapper valve 11.
It is also possible to adopt a configuration in which the following is provided. Further, the number of pulse burners in the combustion apparatus main body 1 may be a plurality of pulse burners other than three, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
