An air box below the distribution plate supplies combustion air to the bed material and paper residue above the distribution plate. A heat exchanging section receives in separate parts ambient air and flue gases from the fluidized bed device for exchanging heat between flue gases and ambient air. The heat exchanging section is connected to the air box for supplying the heated ambient air to the air box for use as combustion air. A control system is employed for controlling the amount of bed material and the dimension of its particles and is arranged to monitor and maintain a process parameter within a predefined range.

Abstract: The invention relates to an X-ray device which operates with only a single image detection device whose format corresponds to the maximum exposure format. In order to facilitate the adjustment of the exposure field for an exposure, a respective set of exposure parameters is stored in a memory for each of the various organs to be imaged; this set includes inter alia an adjustment value for the size of the exposure field for an exposure of the relevant organ. This adjustment value is fetched and the diaphragm unit is automatically controlled in such a manner that the fetched adjustment value is (pre)adjusted.

The invention may be used to remove metals before, during or after the combustion or gasification of fossil fuels, biomass and organic waste.

Abstract: A method of making a hydraulic material which contains metakaolinite and calcium hydroxide from a kaolin-containing compound. The method is performed in a fluidized bed installation having a freeboard under conditions such that the amount of calcium oxide formed is minimized. Preferably, the method is performed at a fluidized bed temperature of 780.degree. C. and a freeboard temperature of no more than 780.degree. C. By minimizing the amount of calcium hydroxide formed, the use of an additional installation for converting calcium oxide to calcium hydroxide is avoided. The starting material is typically waste paper and other residues from recycling of waste paper for reuse in the paper industry. The product may be used to form concrete having a high compression strength.
