PULSATING COMBUSTION DEVICE WITH INCREASED EFFICIENCY AND REDUCED NOISE LEVEL Russian patent published in 2022 - IPC F23C15/00 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy and can be used in heating systems, in particular in water heaters or boilers; in utilization systems operating on associated gas flaring. The pulsating combustion device comprises a combustion chamber, a unit for supplying air and combustible gas connected to it and a flue duct connected to it, including at least one resonant tube connected to the combustion chamber and at least two Helmholtz resonators located in series after at least one resonance tube , each of which is formed by a smoke chamber and a chimney located after it, while the natural resonance frequency of each of the Helmholtz resonators is lower than the combustion pulsation frequency. In the presence of at least three Helmholtz resonators, at least one Helmholtz resonator is connected through the second chimney bypassing the next downstream flue gas of another Helmholtz resonator to the smoke chamber of the third Helmholtz resonator along the flue gas flow.

EFFECT: invention improves the efficiency of the pulsating combustion device while reducing the noise level.
