Abstract
A melting furnace for the thermal treatment of special waste materials containing heavy metal and dioxin is provided. The melting furnace includes a main furnace vessel, the main furnace vessel having a melting end for receiving a melt, and a gas chamber above the melt. The melting furnace further includes at least one charging device for supplying a product to be treated, at least one gas outlet, and at least one discharge chamber, the at least one discharge chamber being separated from the main furnace vessel by a separating wall and being connected to the melting end by a siphon, the at least one discharge chamber having a gas chamber above the melt. At least one first heater projects into an interior of the main furnace vessel, and at least one second heater is provided in the at least one discharge chamber. The separating wall includes at least one opening above a level of the melt, the at least one opening defining a free connection of the gas chamber of the at least one discharge chamber to the gas chamber of the main furnace vessel.
