METHOD OF ACOUSTIC SUPRESSION AND DEVICE FOR ACOUSTIC ENERGY UTILISATION IN EXHAUST SYSTEMS OF ENERGY INSTALLATIONS Russian patent published in 2017 - IPC F01N5/04 

FIELD: engines and pumps.

SUBSTANCE: acoustic energy utilisation device comprises an acoustic path (waveguide) 1, a pulsation turbine unit 2 (one or more), a resonator 3, and an electric generator 4 (can be combined with a turbine). Pulsation turbine 2 includes an electric generator 4, guiding devices 5, and an impeller 6.

EFFECT: reduced energy of the alternating pulsating gas flow by utilising part of its acoustic energy and converting it into electrical energy, which results in a reduction in the noise level, obtaining additional electricity, and increasing the efficiency of obtaining or consuming energy.
