The rotary hearth furnace plant for heating granular high-carbon solids comprises an approximately funnel-shaped hearth, which rotates on a vertical axis and has a central outlet, which is disposed over a rotary table, on which the heated solids are moved by means of blades to an exit. The outlet of the rotary hearth furnace is disposed over the radially outer portion of the rotary table, which has a raised rim and a centrally disposed exit. A gastight hood is disposed between the rim of the rotary table and the rotary hearth. |
