SEPARATION DEVICE FOR OXYGEN CARRIER PARTICLES FROM ASH AND CHEMICAL-LOOPING COMBUSTION FACILITY

摘要

The present invention relates to a device for separating discharged particles, which are discharged from the combustion reactor of a chemical-looping combustion facility after combustion, into ash and oxygen carrier particles. The device for separating oxygen carrier particles from ash for a chemical-looping combustion facility comprises: a supply pipe for supplying discharged particles; a main body connected to the supply pipe to intercommunicate and having an inner space partitioned into a space for separating oxygen carrier particles and a space for discharging ash so that the discharged particles supplied through the supply pipe can be separated into the ash and the oxygen carrier particles; a floating means for separating the oxygen carrier particles among the discharged particles by exerting a floating force to the discharged particles in the space for separating oxygen carrier particles to float the ash and drop the oxygen carrier particles with a specific gravity greater than the specific gravity of the ash; a discharge pipe for oxygen carrier particles arranged to discharge the dropped oxygen carrier particles; and a discharge pipe for ash arranged to discharge the ash.
