Abstract
In the method, the liquid waste substance is vaporized and oxidized in a stream of hot flue gas 4. This stream of flue gas 4 contains the oxygen necessary for oxidation. The essence of the method is that the liquid waste substance is sprayed into the stream of hot flue gas 4 as a fan-shaped flat jet with a component which is perpendicular to the main direction of flow, by means of one or more dual-substance nozzles 6 which are operated in a pulsed mode at a frequency of 5 s.sup.-1 to 70 s.sup.-1, and preferably 10 s.sup.-1 to 20 s.sup.-1, a fan-shaped spray carpet 7 with relatively large droplets of large range and a fan-shaped spray carpet 7 with relatively fine droplets of small range being generated in an alternating cycle at each dual-substance nozzle 6, so that the stream of flue gas 4 is supplied alternately with finely sprayed droplets of small range and large droplets which penetrate the flue gas with a relatively large range of throw. Numerals refer to FIG. 1.
