The feed tube is enclosed in a gaseous exhaust gas conduit and the bulk of gases from the gasifier passes upwardly through descending coal in the feed tube and through apertures in the wall of the feed tube into a chamber formed between the feed tube and exhaust gas conduit while a portion of hot gases from the gasifier passes directly into the chamber to maintain the temperature of the gases when combined in the chamber above their dew point. The combined gases are tangentially discharged from the chamber and, when a plurality of feed tubes are provided, the discharged gases combined and removed through a common offtake conduit.
