Page 25 ABSTRACT OF THE DISCLOSURE Apparatus for conveying particulate material in powdered or granular form from a pressurised container to a collecting container under considerably lower pressure, the apparatus being particularly intended for use in pressurised fluidised bed combustion plants for feeding out ashes and consumed bed material. The apparatus comprises conduit means arranged between the containers and typically built up of a number of tube parts in such a way that, at the transition between the tube parts, a gas/particulate material stream flowing therethrough is bent through an angle, usually either of 90° or of 180°. By choosing a suitable number of tube parts and tube dimensions, a desired feeding capacity and transportation velocites can be obtained. The device has substantially no movable parts, is relatively cheap to produce, has high reliability and is very safe in operation.
