Abstract:
Method for separating entrained particles from a gas in a fluidised bed reactor system which comprises a separation region defined by a cylindrical r-, &phgr;-, z-coordinate system, the method comprising the consecutive steps of:leading the gas in the z-direction (axial direction), diverting the gas to flow substantially in the r-direction (radial direction), while keeping the gas circumferentially distributed in r &phgr;-planes, wherein the gas flows to and/or from substantially the whole circumference of the separation region in the r&phgr;- planes, and mechanically separating the particles from the gas while the gas is flowing substantially in the r-direction, the gas continuing to flow substantially in the r-direction after mechanical separation.
