Abstract (en)
[origin: WO9958902A1] The invention relates to a method for the heat treatment of solids (3), especially waste products, during which the solids (3) in a first stage (5) are burnt/gasified or pyrolysed in the presence of an oxygen deficiency, after which the exhaust gases (6) resulting from the first stage (5) are mixed in a secondary combustion chamber (14) with an oxygenated gaseous medium (15) and are fully burnt. Before being mixed with the oxygenated medium the exhaust gases (6) resulting from the first stage (5) are actively homogenized in a mixing stage (7) with addition of a gaseous medium (8) containing little or no oxygen. The homogenized exhaust-gas stream then passes through a steady-state zone (13) in which it remains for at least 0.5 seconds before the medium (15) is added in a secondary combustion stage (14) to ensure that the exhaust gas is fully burnt. The method provided for in the invention is characterized by simple process steps and a reduced content of pollutants, notably NOx, in relation to prior art.
