PULSATING COMBUSTION APPARATUS WITH INCREASED EFFICIENCY AND REDUCED NOISE LEVEL Russian patent published in 2023 - IPC F23C15/00 

FIELD: energy; heating systems.

SUBSTANCE: pulsating combustion apparatus comprises a combustion chamber, an air and combustible gas supply device connected to the combustion chamber, and at least one resonant channel connected to the combustion chamber. The apparatus is equipped with an exhaust Helmholtz resonator, consisting of an exhaust chamber and at least one exhaust channel connected to it, having an acoustic inductance, the exhaust chamber is connected to at least one resonant channel, and the natural frequency of the exhaust Helmholtz resonator is lower than the combustion pulsation frequency by at least 1.7 times. The device for supplying air and combustible gas includes a first air chamber, which houses at least one air check valve connected to the combustion chamber, at least one air supply pipe connected to the specified air chamber, and the specified air chamber and the specified at least one air supply pipe forms the first air Helmholtz resonator with a natural resonant frequency below the combustion pulsation frequency, and the air and combustible gas supply device includes at least one first combustible gas chamber with a combustible gas check valve located in it, connected to the combustion chamber.

EFFECT: invention makes it possible to increase the efficiency of the pulsating combustion apparatus while simultaneously reducing the noise level.
