摘要： The present invention relates to a method and a plant for treating carbon-containing waste that may comprise mineral fillers and/or potential contaminants.This method comprises: preparing a molten glass bath at a temperature between 1100° C. and 1600° C.; loading the waste to be treated into said molten glass bath; injecting an oxidizer and optionally a fuel under pressure into said molten glass bath by means of at least one hose, one end of which is immersed in said bath, said oxidizer being introduced in a molar amount less than the molar amount of the carbon-containing compounds, thus causing combustion of said waste and generation of hot synthesis gases; implementing heat exchange between a heat-transfer fluid and the hot synthesis gases in conditions allowing simultaneous recovery of at least part of their heat energy and at least part of the heat energy released by their combustion, air being injected sequentially into said gases during said heat exchange to cause self-ignition of the mixture of said gases and air, each injection increasing the degree of combustion.

摘要： The present invention relates to a process and a facility for the continuous vitrification treatment of fibrous materials, and in particular of asbestos and/or of asbestos-containing materials.According to the invention, this process comprises the following steps: a bath of molten glass at a temperature of 1300° C. to 1600° C. is prepared; introduced into said bath of molten glass are said fibrous materials and optionally melting additives chosen so that said bath has, after addition of these fibrous materials and melting additives, the following composition: SiO2: between 30% and 55% by weight; FeO: between 25% and 45% by weight; alkali and alkaline-earth metal oxides: between 15% and 25% by weight; an oxidizer and a fuel are injected under pressure into said molten bath by means of at least one lance, one end of which is immersed in said bath; said oxidizer being introduced in a molar amount greater than or equal to the molar amount of fuel needed to maintain the temperature of the bath between 1300° C. and 1600° C.; and the temperature of at least one portion of the molten glass is lowered so as to render it solid.
