Numerical simulation of co-combustion of diesel and pulverized coal fuel in a small-sized furnace

Abstract

The article is devoted to numerical simulation of diesel and pulverized coal flaring in a small-sized furnace with a vortex oil-steam burner. The results of modeling a small-sized combustion chamber with a steam-oil burner operating in combination with diesel fuel and micro-milled coal are presented. The simulation results showed that the combustion chamber with a steam-oil burner works stably in a wide range of coal dust flow rates. The obtained results of a numerical study can be used in the design of a new burner and furnace device, choosing the optimal operating modes to reduce the concentration of harmful emissions and fuel underburning at the output.
