Abstract: The ecological situation in Kemerovo leaves much to be desired. The cause of a strong violation of the environment is the action of the largest enterprises and plants of the chemical industry. The increase in emissions occurs due to an increase in the total fuel consumption at the enterprises of the power system of Kemerovo. Exceeding the established emission standards is largely due to the work of the three power plants of the city. Therefore, the introduction of an aeroacoustic system at various flue gas velocities and scrubber irrigation densities at the Kemerovo State District Power Plant (GRES) is relevant, including today. One of the promising measures to protect the environment from the harmful effects of the Kemerovo State District Power Plant was the modernization of MB-type dust collectors with the installation of an aero-acoustic system. Testing of modernized ash collectors to assess the effectiveness of the applied intensification scheme showed the effectiveness of the aerodynamic system. For the turbulization of the dust-gas flow with sprayed irrigating water, aeroacoustic intensifiers were installed in the throat of the Venturi tubes, which improve the coagulation of the fine fraction of the dust-gas flow. The long-term operating experience of Venturi scrubbers equipped with an aero-acoustic system confirms their reliability, ease of operation and high efficiency. The degree of purification of flue gases from the solid components increased from 96% to 98.1%.
