SciELO - Brasil - EVALUATION OF LIMESTONE IMPURITIES

At 12% CO 2 (typical of boilers) the dolomite calcination occurs in a two-step pattern, which is clearer at 80% CO 2 (oxy-combustion), because the separation of peaks increases. Thus, a higher temperature in a CO 2 atmosphere is necessary for the calcination to take place completely (~50 °C higher than in oxidizing conditions).
