PULSATING COMBUSTION HEAT GENERATOR Russian patent published in 2019 - IPC F23C15/00 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering. Pulsed combustion heat generator comprises combustion chamber with valve-mixer and resonator tubes, wherein combustion chamber with resonator tubes is arranged in jacket with heat carrier, forming heat exchanger, and an exhaust pipe consisting of an additional resonating device in the cylindrical chamber and a resonator in the form of a pipe with length equal to 10…12 pipe diameters, and reactive active noise silencer. Cylindrical chamber of additional resonating device is made coaxially relative to heat exchanger and communicated from below with pipes-resonators through end cavity formed by heat exchanger flange and heat exchanger bottom, and from above with additional resonating device resonator through branch pipe, wherein volume of cylindrical chamber of additional resonating device is 50…200 % of total volume of combustion chamber with resonator tubes, wherein the heat carrier jacket is made coaxially relative to the cylindrical chamber of the additional resonating device and formed from a shell, a lower and an upper flanges, which is interconnected by means of, for example, a connection pipe with a jacket of the heat exchanger.

EFFECT: increased heat removal, reduced noise of installation up to 65 dB due to increased resonance frequencies of pressure fluctuations.
