Abstract (en)
[origin: FR2858570A1] The organic waste is heated in a fixed or rotating furnace (1) in an atmosphere deprived of oxygen, by intimately mixing previously superheated steel balls or pellets with the waste as it enters the furnace. For thermolysis the steel balls enter the furnace at a temperature of between 600 and 1100 deg. C and leave at a temperature between 500 and 850 deg. C. For drying, the steel balls enter the furnace at a temperature of between 500 and 600 deg. C and leave at a temperature of between 120 and 140 deg. C. The balls are superheated in a gas, induction or electric furnace (10) and are between 20 and 50mm diameter. An independent claim is made for an installation to carry out the above process, with a fixed or rotating furnace into which the waste and steel balls are channeled; means of feeding in the wastes; means of recovering volatile products from the treatment; means of recovering solid residues from the treatment; means of recovering the steel balls for recirculation and a furnace for heating the balls. A further INDEPENDENT CLAIM considers submitting a solid, powdered or paste material to a thermal treatment (heating or cooling) to alter its physical or chemical properties by mixing with steel balls or pellets which have previously been taken to a temperature such that at the outlet from the treatment the treated material and the balls are at the desired temperature.
