Abstract
Applying the oxyfuel process to the circulating fluidized bed technology, one of the major process concerns is the possible deposit formation on the immersed surfaces of the external heat exchangers caused by the recarbonation of unused calcined desulphurization sorbent (CaO). This paper presents first results from experiments carried out under air- and oxyfuel atmospheres in a lab-scale BFB of calcined limestone with an in-bed cooled deposition probe. It was found, that under oxyfuel conditions, the strong recarbonation of calcined particles on the cool surface lead to hard and stable carbonate depositions.
