Abstract: The present invention relates to a fluidized bed system having a sparger capable of minimizing a blockage by solids and controlling method thereof. And, more specifically, the present invention relates to a fluidized bed system having a sparger capable of minimizing a blockage by solids comprising a fluidized bed reactor to store a solid layer with a certain height and to fluidize the solid layer by using fluidization gases; a sparger having a pipe shape submerged in the solid layer and having a plurality of gas-discharging holes to spray fluidization gases onto the solid layer; and a gas-supplying line having its one end contacting a gas-supplying source and the other end connected to the sparger, wherein fluidization gases are introduced through the gas-supplying line into the sparger by driving the gas-supplying source, the fluidization gases are sprayed through the gas-discharging holes onto the solid layer, the gas-supplying source is placed higher than the sparger and the height difference (Hg) between the gas-supplying source and the sparger is greater than the height of the solid layer.

Abstract: The present invention relates to a CLC and operation method thereof equipped with a loop seal separator using magnetic oxygen carrier particles and a magnetic separator. And more particularly, the present invention relates to a loop seal separator using magnetic oxygen carrier particles and a magnetic separator, wherein the loop seal separator comprises a duct into which the ash and magnetic oxygen carrier particles, discharged from a reducer, flow; a magnetic separator to separate the ash from the magnetic oxygen carrier particles, flowing into the duct, by magnetic material; an ash discharge pipe to discharge the ash, separated by the magnetic separator; and an oxygen-carrier-particle discharge pipe to encourage the magnetic oxygen carrier particles, separated by the magnetic separator, to flow into an oxidizer.
