For feed this is equal to the PSD of the limestone, since Ca is practically only the compound CaCO 3. The cumulative PSD is shown in Figure 3. In air combustion, the bed material containing Ca is smaller than in the feed or in oxy-fuel combustion, which is probably due to primary fragmentation in the calcination stage.
