Abstract
Experimental modeling of calcination of dusty carbonate particles is performed in an isothermal flow of combustion products in a reactor holding the necessary temperature due to the intermediate introduction of inflammable gas into afterburning. The decomposition kinetics of carbonate particles in combustion products is analyzed applying the available publications in order to predict the efficiency of such reactors for practical use and to determine optimal process modes. Special attention is paid in this study to comparison of theoretical and experimental data in boundary calcination regimes, i.e., at parameters, below which calcination in combustion products is already impossible. Taking into account that one important purpose of rapid dust calcination is the preparation of active lime, which effectively binds “acidic” gases in combustion products of power installations, control over the removal of SO x from gases by dust in a reactor was performed.
