The waste gas generated during the combustion process is fed to an after burning chamber, in which the minimum temperature of between 850 and 1200°C is maintained for a residence time of at least 2 seconds. The waste gas volume from this process is generally assumed to be about 7,000 m3 (dry) per Mg of waste.
