  • This cold water injection into the raw synthesis gas stream also binds liquid or solid particles entrained in the gas stream, so that a well pre-cleaned raw synthesis gas is obtained after the rapid cooling.

Les étapes de traitement comprennent une étape basse température avec exclusion d'oxygène, ainsi qu'une étape haute température avec apport en oxygène à des températures supérieures à 1000 °C. L'étape haute température présente une zone de stabilisation et une sortie destinée au mélange gazeux produit durant l'étape haute température, en particulier dans la zone de stabilisation. La zone de stabilisation est dotée de dispositifs servant à l'injection d'oxygène et de carburant, lesdits dispositifs permettant d'injecter du carburant et de l'oxygène en excès du point de vue stoechiométrique durant le démarrage du processus de chauffage de la zone haute température. Les gaz d'échappement sont alors directement acheminés vers une cheminée via au moins une soupape.
