Abstract

Embodiments herein relates to a calcination system 100. The system 100 comprises an electrically heated calcination reactor 108. The electrically heated calcination reactor 108 is configured to convert input material into calcination process products comprising a solid compound in the form of calcium oxide and a gas in the form of carbon dioxide. The system 100 further comprises a particle separator 110 arranged to receive input material in the form of particles of lime mud. The particle separator 110 comprises a chamber 401 configured to hold a fluid bed 402 of particles mixed with gas, into which fluid bed 402 gas is fluing from underneath 403, thereby separating smaller particles from larger particles by lifting the smaller particles upwards in the flow of gas. The particle separator 110 is coupled to a transfer channel 404 arranged to provide the flow of the separated smaller particles mixed with gas to an injection arrangement 106 injecting the provided input material into the electrically heated calcination reactor 108.
