Thermodynamic assessment of the possibility of emission of submicron particles in the process of coal combustion

Methods of chemical thermodynamics of multicomponent reactive systems are used to study the distribution of the most volatile components (potassium and sodium) in the products of combustion of 15 types of coal. The effect of the mineral part of coals and various potassium and sodium compounds on the temperature of their transition into the gas phase is investigated. It is shown that the distribution of potassium and sodium in the products of coal combustion depends on the speciation of these elements in the initial coal; the mineral part composition; the ash content of coals; and the sulfur, potassium, and sodium content of the initial coals.
