ABSTRACT:
A hot gas cyclone separator is provided with a segmented dip tube whose smooth sheet metal dip-tube segments have tops which are securely fastened to a cap of the separator in hook like manner by U-shaped angle rails. The adjacent lower ends of the dip-tube segments may also be interconnected by angle rails having U-shaped profiles which serve to protect the lower end of the dip tube from excessive wear caused by the impinging hot gas/solids suspension.
