Abstract

The article is devoted to numerical modeling of coal fuel flaring in a steam-oil burner. The results of modeling an oil-steam burner developed at IT SB RAS and a new torch burner operating on diesel fuel with partial replacement of it with micro-milled coal are presented. A comparison of the calculation results with the experimental data showed their good agreement both in terms of the temperature level and the concentration of the gas components of the combustion products. The simulation results showed that the new burner operates stably in a wide range of pulverized coal flow rates. The obtained results of a numerical study can be used in the design of a new burner device, choosing the optimal operating modes to reduce the concentration of harmful emissions and fuel underburning at the output
