Title
(EN) METHOD FOR OBTAINING PRE-NEUTRALISED, REFUSE- DERIVED FUEL, FUEL OBTAINED IN THIS WAY AND ITS USE IN COMBUSTION
(FR) PROCEDE D'OBTENTION DE COMBUSTIBLE PRE-NEUTRALISE DERIVE DE DECHETS, COMBUSTIBLE OBTENU DE CETTE FAÇON ET SON UTILISATION EN COMBUSTION
Abstract
(EN)
A method is described for the production of refuse-derived fuel, in particular from urban solid waste, which is subjected to rough grinding, aerobic digestion in a closed space and in a flow of air, possible screening to separate the fine screened product and possible removal of metals, final grinding to a medium (approximately 1 decimetre) or fine size (a few centimetres), and compacting for transport and possible storage, before incineration. According to the invention, preferably during the phase of fine grinding, the addition of soda to the waste is foreseen, in at least a sufficient quantity for neutralising the acidity present in the same. The object of the invention is also the refuse-derived fuel obtained in this way, which can be used in incinerators, possibly in co-combustion with waste not neutralised at the outset.
(FR)
L'invention concerne un procédé de production de combustible dérivé de déchets, en particulier issu de déchets urbains solides, qui sont soumis à un broyage grossier, à une digestion aérobie dans un espace fermé et dans un flux d'air, à un éventuel tamisage pour séparer le produit finement tamisé et à un éventuel enlèvement des métaux, à un broyage final jusqu'à une granulométrie moyenne (approximativement 1 décimètre) ou fine (quelques centimètres), et à un compactage en vue de leur transport et de leur éventuel stockage avant incinération. Selon l'invention, de préférence pendant la phase de broyage fin, l'addition de soude aux déchets est envisagée, dans une quantité au moins suffisante pour neutraliser l'acidité qui s'y trouve. L'invention concerne également le combustible dérivé de déchets obtenu de cette façon, qui peut être utilisé dans des incinérateurs, éventuellement en co-combustion avec des déchets non neutralisés au départ.
