Title (EN) METHOD AND APPARATUS FOR CARRYING OUT CHEMICAL AND/OR PHYSICAL PROCESSES IN A FLUIDIZED BED
(FR) METHODE ET APPAREIL POUR LA MISE EN OEUVRE DE PROCEDES CHIMIQUES ET/OU PHYSIQUES DANS UN LIT FLUIDISE
Abstract:
(EN) A method and an apparatus for carrying out, at least two fluidized beds (4, 5), different chemical and/or physical processes between a heavier medium and two or more mutually different, lighter fluidizing media (F1, F2), for example combustion and gasification of solid fuel by means of air and water vapour, respectively. The beds are disposed spaced from each other but with an open communication between them at their lower ends and the one fluidizing medium (F1) is utilized for circulation of the heavier material (H) between the beds. This one fluidizing media (F1) is blown in at the open communication such that it does not mix with the other fluidizing media of the beds and the fluidizing media are led off from the beds in separate paths (16, 19).
(FR) Methode et appareil pour la mise en oeuvre, dans au moins deux lits fluidises (4, 5), de differents procedes chimiques et/ou physiques entre un milieu plus lourd et deux milieux de fluidisation differents ou plus (F1, F2), plus legers, par exemple la combustion et la gazeification de combustibles solides par l"air et la vapeur d"eau, respectivement. Les lits sont ecartes l"un de l"autre mais il est prevu une communication entre eux a leurs extremites inferieures et le milieu de fluidisation (F1) est utilise pour faire circuler le materiau plus lourd (H) entre les lits. Le milieu de fluidisation (F1) est insuffle au niveau de ladite communication de telle facon qu"il ne se melange pas a l"autre milieu de fluidisation des lits et les milieux de fluidisation sont canalises vers l"exterieur selon des trajets separes (16, 19).
