Abstract
The HTW-pilot plant (circulating fluidized bed) of the institut of Fer rous Metallurgy of the Technical University of Aachen is used for lean gas production with carbon containing fuels. Theoretical consideratio ns about increasing residence time of solid matter and decreasing unwa nted discharge of finest particles by changing the free-boards geometr y have been investigated in a 1:1 modell at room temperature. The disc harge could be decreased by up to 34%. The diameter of the discharged particles decreased. The residence time of solid matter increased sign ificantly by building up two fluidized beds one upon another
