Thermodynamics of the Formation and Condensation of the Vapors of Potassium and Sodium Compounds on the Combustion of Russian and Chinese Coals

摘要

The thermodynamic distribution of potassium and sodium in the products of the combustion of six types of coals was considered. The effects of the mineral matter of coals and various potassium and sodium compounds on the temperature of their transition to a gas phase were studied. It was found that the distribu tion of potassium and sodium in coal combustion products depends on the chemical speciation of the ele ments in the parent coal and on the Ca/Si ratio.
