The composition, physical properties and volume stream of exhaust gases emitted into the atmosphere as a result of biogas combustion in gas-powered energy generator as well as chemical composition of precipitates formed in the exhaust gases/water crossflow heat exchanger are investigated. The content of such basic components of combustion gases as CO2, O2, H2O, N2, such toxic substances as SO2, SO 3, NO, NO2, CO, HCl as well as acid and water dew-points are determined. Precipitate analysis included determining loss on ignition and the content of sulphur compounds, Fe, Mn and Mg. The results of the study allow us to evaluate the noxiousness of exhaust gases in the atmospheric air, to identify the causes of precipitate formation in the heat exchanger and to explore the ways of dealing with the problem of deposit precipitation.
