PURPOSE: To shorten the plant idle time for repair by removing a high temperature lower part, arranging a preheated reserve unit at an operating position and introducing a combined burner with an oxygen supply tube into the cooling jacket of the reserve unit. CONSTITUTION: Molten liquid is drained from a molten bath and a combined burner with an oxygen supply tube, which is provided with a cooling jacket, guided through the wall of a lower hearth is removed from the cooling jacket. Removing a connecting element between an upper hearth and the lower hearth of the high temperature reactor and slowly lowering the lower hearth, the high temperature lower hearth is removed from the operating position of it. Arranging a preheated reserve hearth to the operating position and connecting it to the upper part of the high temperature reactor by press fitting, the combined burner with the oxygen supply is introduced into the cooling jacket of the reserve unit of the lower hearth. Therefore, a worn part with high load can be restored rapidly to a necessary operating state.
