<p>The oven comprises a single opening for charging purposes which is obturated by a series of leaves of small longitudinal superposed doors, the lower edge (17) of a leaf covering the upper edge (16) of an immediately lower leaf. The leaves of the small doors may pivot by 190o or slide laterally. The bottom of the oven may be provided with an assembly of doors (33) such as the small doors. A gap separates the front edge of the bed plates (21) and the plane of the inner face of the small doors. The bed-plates (21) are relatively thin and perforated plates. They may be removed. The ends of the hooking bar of a charging system may slide in the uprights of the charging opening or may be retained in stirrups arranged on either side of the small doors.</p> |
