Abstract:
1. An elongated cyclone separator vessel having an upper end and a lower tubular part which has an inner wall defining a lower tubular part cross-sectional area, wherein said elongated cyclone separator vessel is provided with an inlet for receiving gas and solid particles and a gas outlet at said upper end, wherein the lower tubular part is provided with a closed lower end, through which said closed lower end a substantially vertical particle withdrawal conduit, which defines a smaller cross-sectional area, extends from a position below the closed lower end to a position within the lower tubular part and below the inlet for receiving gas and solid particles, wherein said substantially vertical particle withdrawal conduit is provided with an opening for withdrawing solid particles from within the elongated cyclone separator vessel, and wherein said smaller cross-sectional area and said lower tubular part cross-sectional area define a space having a lower part and an upper part between said substantially vertical particle withdrawal conduit and said inner wall of the lower tubular part, and wherein provided within the lower part of said space is main means for adding a primary fluidizing medium.
