(EP750731-A1)      In a process to fully incinerate hydrocarbon compounds mixed with halogens such as PVC, the substances are incinerated in a fluid bed chamber in the presence of a fluidising agent in both solid and gaseous form. The novelty is that the hydrocarbon compounds are first mixed in a preliminary stage (7) with recirculated hot sand as the heating agent, preventing the formation of high molecular condensation products. During this process water is separated from the residues. The hydrocarbon compounds are split into hydrogen and transient low-molecular hydrocarbons in a stream atmosphere. The combustible residues are then burned with the now cool sand, and the hydrogen gas mixture generated in the preliminary stage is then burned with the effluent gas in the fluid bed combustion chamber. The hot gases are then cooled in the normal way.    USE -   The process incinerates hydrocarbon compounds arising from pre-sorted domestic refuse such as plastics, hydrocarbons, coated, uncoated paper, sludge and material containing halogens such as wood waste mixed with PVC.    ADVANTAGE -   The process prevents the formation of plastic slag, soot and dioxin, and maintains the fluid bed temperature in the sand non-molten range, preventing the formation of excessive CO and organic hydrocarbon emissions in smoke.    (EP750731-B1)      Process for complete combustion of carbon composites, for example plastic materials, hydrocarbons, uncoated or coated paper, sewage sludge and mixed wood wastes with halogen containing material, such as PVC, in a fluidised bed combustion chamber (1) in the presence of fluidising material in a solid a gaseous form, for example sand and water vapour, and the carbon composites are initially partially decomposed in a pre-stage (7), whereafter still combustible remainders are combusted and gaseous reaction products produced in the prestage (7) are combusted with the waste gas of the fluidised bed combustion chamber (1), characterised in that, for the purpose of preventing a formation of high molecular condensation products, the conversion of carbon is carried out in two stages, and carbon composites to be combusted are entered with at least 30 times the weight volume of hot sand from the recirculation as a heat carrier in low exygen atmosphere into a turbulent fluidised bed, which is fluidised by delivery of water vapour (13), of the pre-stage (7) of the fluidised bed combustion chamber (1), and the carbon composites are split in a water vapour atmosphere whilst forming water gas and light volatile low molecular hydrocarbons, and discharging decomposing reactions of light volatile low molecular hydrocarbons, which formed during gasification by melting or splitting the hydrocarbon composites, in a water vapour containing atmosphere at temperatures above 400oC, and gaseous reaction products, such as water gas and light volatile low molecular hydrocarbons, are separated from sand and remaining solid and low volatile portions of the carbon composites, and in the fluidised bed combustion chamber (1) the remaining solid or low volatile portion of the carbon composites, such as hydrocarbons and produced carbon, are combusted with further combustible materials, such as coal and/or gaseous reaction products from gasification reaction, with a surplus of air whilst heating the sand.
