LONG-TERM CYLIND PROCEDURE FOR THE TREATMENT OF MATERIAL AT HIGH TEMPERATURE IN A GAS MOSTER UNDER HIGH-PRESSURE

摘要

Sealing means useful in connection with cylindrical, elongated furnaces wherein materials are treated at high pressures and high temperatures. Such furnaces generally include a cylinder, end closures and a cooling plate structure carried by the end closure and disposed internally of the furnace. The sealing means comprises an attachment ring for retaining the cooling plate in position on the end closure and a number of annular seals disposed in sealing relationship with respect to the gap between the attachment ring and the cooling plate structure. A draining channel is provided to intercommunicate said gap and the atmosphere surrounding the furnace.
