Ecological Assessment of Industrial Waste as a High-Potential Component of Slurry Fuels

Research output: Contribution to journalArticlepeer-review

Abstract

Statistical analysis findings are presented for typical industrial waste accumulated in the Extreme North and the Arctic, as well as abandoned industrial regions. The analysis has been performed of industrial waste formation in regions exporting energy resources (coal, oil, and gas). A group of waste has been identified that is accumulated in the largest volumes. Advanced methods of its recycling are considered. Advantages and limitations of these methods are outlined. An approach is suggested that is based on preparing slurry fuels from industrial waste by adding water. Laboratory experiments with such slurry fuels have been conducted. Typical values of the following energy performance characteristics are determined: ignition delay times, minimum threshold temperature of combustion initiation, maximum combustion temperature, and heat of combustion. Anthropogenic emission concentrations have been measured (the most hazardous of them are sulfur and nitrogen oxides) from the combustion of slurry fuels under study. Economic, environmental, and energy performance indicators of slurry fuels have been compared with those of conventional energy resources. Graphic Abstract: [Figure not available: see fulltext.]
