The goal of the invention consists in making available a method for supplying fuel to a pressurized gasification system, which ensures, in economically efficient manner, that the emission of pollutants from the coal transfer and the transport is minimized or completely avoided. This is achieved in that a gas that contains at least 10 ppm vol. CO is used for transfer and/or conveying, whereby a gas that contains oxygen is mixed into this gas, and that this gas mixture is heated to a temperature that oxidizes at least 10% of the pollutants contained in the gas.
L'invention vise à mettre au point un procédé pour alimenter une installation de gazéification sous pression en combustible, de sorte à garantir de manière économique une réduction ou une élimination totale d'émissions polluantes dues au sassement du charbon et au transport. A cet effet, il est prévu d'utiliser pour le sassement ou le transport un gaz contenant au moins 10 ppm vol. de CO, un gaz contenant de l'oxygène étant mélangé avec ledit gaz et le mélange gazeux obtenu étant porté à une température entraînant l'oxydation d'au moins 10% des polluants contenus dans les gaz.
