Abstract The paper gives results of an analysis of the fundamental processes for the injection of CaCO3 and Ca(OH)2 for the removal of SO2 from combustion gases of coal-fired boilers, on the basis of experimental data and a comprehensive theoretical model. Sulfation data were obtained in a 30-kW isothermal gas-particle transport reactor at conditions simulating those of upper-furnace injection. The theoretical model accounts for particle structure, calcination, sintering, sulfation, and heat and mass transfer. Pore diffusion, product-layer diffusion, and sintering appear to be the principal processes that govern the rate of SO2 capture for the hydrate particles of interest for commercial dry sorbent injection.
