Abstract

The estimation of laboratory researches of quantitative and qualitative indicators of toxic compounds in the process of combustion of solid domestic wastes is given. A schematic diagram of an installation for analyzing samples of combustion products during the combustion of solid domestic waste samples is presented. It is concluded that a reliable assessment of hazardous situations in case of fires in solid domestic waste landfills and prediction of their development can be ensured by using experimental laboratory studies to obtain reliable data. The proposed methods for determining the fire and technical characteristics of combustible materials of solid domestic waste during fires, the corresponding measurement procedures and modern analytical equipment have made it possible to obtain high-precision initial data characterizing the concentration and composition of the smoke particles, the dispersed composition as a function of the aerosol size distribution and the aerodynamic diameter. According to the calculations, graphs of emission of heavy metals into the atmosphere and their content in the ash during the burning of briquettes of solid domestic waste, as well as the speed of the emission of smoke particles with different densities in the air were constructed
