Abstract

Procedure for cooling and keeping the sealing surfaces of the closing flaps of the reserve hoppers of a tank furnace loading installation that are in communication with the furnace head, characterized in that the flaps, during furnace operation, they are constantly bathed by a circulation of a cooling agent that is introduced into the charging installation in the area between the furnace head and the closing flaps, the pressure of the introduced cooling agent being chosen to be somewhat higher than the prevailing pressure into the gullet to produce a stream of coolant toward the interior of the furnace.
