Abstract

Improvements in continuous firing furnaces of ceramic nuclear fuel pellets, under neutral or reducing atmosphere, of the type comprising a longitudinal axis tubular enclosure, provided with heating means distributed throughout the enclosure, comprising a displacement hearth longitudinal of the wafers containing the tablets, gas injection means in the two end portions of the oven, gas aspiration means in an intermediate zone between the preheating and calcining zones, and condensation of the binder that is contained therein, and means of circulation of the trays along the hearth from a tray for introducing the trays arranged in one extreme portion of the oven to a tray for removing the trays in the other extreme portion of the oven, characterized in that the two traps They are joined in a watertight way by a conveyor that crosses a handling box with n gloves in which a station for loading the wafers is juxtaposed with sub-waffles containing the tablets to be calcined, and a position for unloading the sub-waffles containing the calcined tablets.
