Abstract
A high temperature-high pressure furnace which includes a cylindrical pressure chamber formed of a hollow cylindrical wall and two end closures therefor, a cylindrical sheath positioned within the cylindrical wall to provide a gap therebetween, and heaters positioned within the cylindrical sheath in order to provide a furnace space therewithin. The sheath at one end is sealingly connected to one of the end closures and at the other end is provided with a channel to provide fluid communication between the furnace space and the gap when an insulating lid is positioned over this other end of the sheath. The end closure to which the sheath is sealingly connected is provided with passageways which allow for fluid circulation therethrough and between the gap and the furnace space.
