Abstract

Pour une production rationnelle d'énergie électrique, un gaz chaud dépoussiéré (10) est envoyé dans une turbine à gaz. Le gaz chaud chargé de poussière (1), produit par combustion en lit fluidisé sous pression ou par gazéification du charbon, à une température de 850 °C et sous une pression de 16 bars, est ensuite épuré dans une installation de dépoussiérage (4, 8, 9). Cette dernière comprend un coagulateur (4) pour la fixation des particules de poussière les unes sur les autres et deux cyclones montés en série (8, 9) pour la séparation de la poussière (13, 14). Le coagulateur (4) présente un faisceau de tubes (5) équipés de vibreurs (6). Un premier cyclone (8) est équipé d'une électrode (11) assurant une séparation plus efficace de la poussière. Des filtres à lit tassé ou des dispositifs d'injection de produits chimiques peuvent être prévus en amont, à l'intérieur ou en aval du coagulateur (4), afin de réduire les gaz à effet de serre et/ou les gaz corrosifs.
