C. with a residence time of at least about 0.1 second, an excess of at least about 5% by weight of oxygen, based on the organic carbon to be burnt, being present in the combustion chamber. Advantageously the polychlorinated organic compound is present in the fuel feed in about 0.1 to 30% by weight.
