This paper presents the results of an experimental study of the formation of aerosol particles at the outlet of a flue gas duct of power equipment under the influence of low-frequency sound fluctuations (acoustic field) by burning a gaseous fuel. To measure the concentration and velocities of the aerosol particles in the flue gas, a laser Doppler anemometer, adapted to the conditions of the test rig, was used. The applied technique allowed to detect signals of solid aerosol particles with a size of 4-70 μm directly in a flue gas duct. In our experiments the existence of particles with a size over 40 μm was not detected. That is, there were no large agglomerates of aerosol particles in the flow. Besides, the study of aerosol particles enabled us to explain the (increased content of CO because of the CO)2 decay. Thus, monitoring of aerosol particles allowed to receive additional information about the combustion process. [ABSTRACT FROM AUTHOR]
