Abstract
The furnace according to the invention makes it possible to continuously vitrify and/or densify toxic materials, such a nuclear waste, by using microwaves. The furnace contains two vertical ends connected by a horizontal melting vessel. The materials to be melted and the microwaves are introduced at the first end. The melting vessel has a constant cross-section as a result of a horizontal upper wall in order to aid the distribution of the power of the microwaves over the surface of the molten bath. Preferably, the second end is provided with a piston making it possible to regulate the return of non-absorbed microwaves.
