Abstract
Use of high stacks for removal of hydrocarbon fuel combustion products at thermal power plants allows to significantly reduce air pollution levels. The article discusses a method for estimating the rise rates and buoyancy flows of smoke emissions from thermal power plant stacks based on similarity and dimensionality relationships, hydrodynamic models, and satellite information. The proposed method was tested using a winter satellite image of smoke plumes and their shadows on the earth's surface as applied to the high stacks of the Gusinoozerskaya GRES. The wind and air temperature fields were calculated using the WRF mesoscale model adapted to the Baikal natural territory. The results of the study enable, under conditions of very limited input information, to characterize the active stage of smoke plume rise and to monitor the modes of impurity emissions from industrial enterprise stacks based on buoyancy flow estimates.
