Abstract
Thermodynamic analysis of the composition of combustion products have been performed for 15 types of coals with and without allowance for potassium and sodium aluminosilicates. Based on the results obtained, a closed model has been proposed for the formation of submicron particles in the combustion products of the coals, which enables one to obtain the upper estimate for the content of submicron particles in these products. The bulk condensation of potassium sulfate vapor in the flow of the combustion products and upon their cooling along a technological path has been numerically simulated by means of computer-assisted realization of the proposed model. The number concentration and size distribution of the formed particles have been determined. Agreement with experimental data on the average particle size has been reached at a reasonable value of a free parameter of the model.
