Abstract
A tubular reactor for heat treatment of granular material in suspension has a vessel (1) up through which a flow of gas and burning fuel passes. The vessel contains vanes (20) which cause the gas to follow a helical path and fling outwards entrained material, which falls down the vessel wall and is displaced inwardly by frusto-conical rings (30).
