Abstract

Closure for top charging structure for high pressure shaft furnaces consists of an outer bin discharging into an inner buffer storage chamber which in turn discharges into the furnace incorporating a lid-operated seal consisting of a hinged lid which is pressed against the inlet hold of the buffer chamber from the inside and which, engaged a circular seal round this hole, thus making the chamber gas tight.
