Abstract

Industrialized regions of the world are actively polluting the environment. In this research, we consider one of the developed industrial regions, Siberia (Russia), as an example. The paper presents typical volumes of annually stored waste, in particular, waste of oil production and a refinery (76 800 tons), liquid and watered waste of the municipal sector (167 875 tons), and food waste (5906 tons). The parameters of ignition and combustion of such wastes are studied in the compositions of coal-water slurry fuels with petrochemicals. The experimental results demonstrate that most of the wastes in the industrial region under study have high potential (according to environmental, economic, and energy criteria) as additives to fuels. In particular, a comprehensive comparative analysis shows that the ignition delay time for fuel slurries with waste can be reduced by 10-60%; the minimum ignition temperature, by 10-45 °C; and concentrations of NOx and SO2 emissions, by 5-50%. The combustion heat of composite fuels can be increased by 5-20% when using admixtures from industrial waste.
