“…2 and 3 show, respectively, the schematic diagram of the simulated tangential burner device and the used computational grid. The papers [15,16] present the results of comparing the data obtained by calculation and in an experiment performed at the Institute of Thermal Physics of the Siberian Branch of the Russian Academy of Sciences when burning diesel fuel [15] and a mixture of diesel fuel and coal [16]. It is shown that the calculation model reproduces the experiment well, both in terms of temperature and gas composition (Fig.…”

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.

“…Therefore, the problem of further developing mathematical models of the studied process of liquid fuel combustion with steam injection is topical. This study is a continuation of the numerical studies of the authors [42,45]. Unlike previous studies, which were focused on the features of the physicochemical processes occurring in the burners under consideration, this study examines the influence of various numerical methods on the accuracy of the simulation of the combustion processes.…”

Currently, thermal power plants operating on hydrocarbon fuels (gas, fuel oil, peat, shale, etc.) are one of the main sources of electricity. An effective and promising method for suppressing harmful emissions (NOx, carbon oxides, soot) from the combustion of fossil fuels is the injection of steam into the combustion chamber. The influence of various mathematical submodels was studied on the accuracy of the numerical simulation of the process of n-heptane combustion in a laboratory burner with steam additive to the reaction zone as a promising chemical engineering method for the disposal of substandard liquid fuels and combustible waste with the production of thermal energy. The problem was solved in a three-dimensional stationary formulation. Systematic verification of these submodels, and a comparison of the results of the calculation with the experimental data obtained were carried out. The comparison with the experimental data was carried out for gas components and temperature distribution at the burner outlet; high agreement of the results was achieved. Optimal submodels of the methodology for calculating the process of fuel combustion in a jet of steam were determined. The best agreement with the experiment data was obtained using the EDC model in combination with a mechanism consisting of 60 components and 305 elementary reactions. More correct simulation results were obtained using the RSM turbulence model and the DO radiation model.
