N2 - This project was a joint venture between Austrian Energy and Environment Co. and the Institute of Process Technology and Industrial Environmental Protection. The aim was to build a downsized Circulating Fluidized Bed (CFB) cold model whose height is about 4.5m based on the commercial CFB boiler at RV-Lenzing of AVE Co. to investigate and optimize the current CFB boiler in Lenzing as well as any CFB boiler to be built in the future. This paper includes the domcumentation of the installation and the sesnoring system. Furthermore, the experimntal results are documented, as there are the test operations of the built system, tests with a new designed siphon, bd material behavior in the external Fluidized bed Heat Exchanger(FHE) as well as in the CFB parts, the relationship of the mass rate of circulating particles with pressure drop in a riser and the influences of particle loading in the cyclone on the cyclone pressure drop.
