Method for glazing residues and apparatus for carrying out this method

摘要

Process for vitrification of waste enclosed in a container (10). According to the invention the said process comprises the stages consisting, in a furnace (200) heated to a temperature Tf higher than the melting temperature Tc of the container by a high-temperature generator (100) with a jet (110) of heat directed along an axis D and in which the jet temperature is Tj, - in arranging the axis D of the said heat jet at an angle ( theta 1) to the normal (N) to the furnace varying from 15 to 20 DEG , - in placing the container in the furnace, the temperature difference Tf-Tc being adjusted so that the said heat jet (110) brings the waste confined in the said container (10) to a temperature Td which is higher than the average temperature Tf of the furnace, - in carrying out the complete vitrification of the container and of the waste into a vitreous magma (11) at a temperature substantially equal to the temperature Tf of the furnace, - in removing and recovering the said vitreous magma from the furnace. Application to the treatment of waste without prejudice to the environment.
