In other words, when sound travels through the sand as vibrations, the sand 2' of the sand box 2 is polished against itself and energy is absorbed by the friction, resulting in great vibration-proofing and sound-proofing effects. Sand is ideal for absorbing low-frequency, high-energy sounds such as pulsed combustion. The oil tank 1 having such a structure can effectively prevent resonance noise caused by amplifying the vibration sound of the iron plate, and can reduce the conventional noise of approximately 50 horns to about 40 to 45 horns.

The pulse combustion device A forcibly feeds a mixture of fuel gas and combustion air to the combustion chamber 3, causes explosive combustion within the combustion chamber 3, and instantly discharges the combustion exhaust gas to the tail pipe 4. The combustion chamber 3 is temporarily vacuumed and the next mixture is sucked into the combustion chamber 3 again and ignited and exploded.The cycle of air supply, ignition explosion, expansion, and exhaust is repeated 80 to 100 times per second, and the exhaust flow is The gas is discharged outside the vessel via an exhaust pipe 5 connected to the tail pipe 4.

As explained above, this idea is based on the heater main body 1.
It has a simple structure in which the outer wall of the chamber is covered with a damping material filled with granular damping material 2' such as sand or earth.It suppresses the vibration sound of high frequency components of 8000 Hz or more associated with pulse combustion, and also suppresses the vibration sound of the damping material. It has the effect of absorbing low-frequency, high-energy sounds, preventing resonance, and significantly reducing noise. However, when the pulse combustion device A is used as a heat source, its exhaust flow velocity is high, and the heat dissipation effect in heat exchange parts such as the combustion chamber 3 and tail pipe 4 is also high, so the heat transfer efficiency is high and energy saving is excellent. Therefore, it is effective as a heating source for hot water storage type water heaters, hot water heaters, fryers, etc., and the practical value of the pulse combustion type heater is that it can eliminate unpleasant resonance of high frequency components and low frequency components with this invention. can be made more expensive and its spread can be promoted.
