Abstract: An arrangement for gasification of fuels within the range from fine grain fuel to dust shaped fuels, in a dust cloud with gas comprises a gasification reactor provided with at least two burners, a supply container for accommodating a fuel, a distributor connected to the supply container for receiving the fuel from the supply container, and a plurality of conduits connected with the distributor and supplying the fuel from the latter to the burners, the conduits having a different geometrical parameter including at least one of a length and a direction.

Abstract: An arrangement for monitoring pressure pulses in gas/particulate material media flowing through pipelines and/or containers includes an annular metallic housing which surrounds a flow passage and has in its interior an annular chamber which extends around the flow passage and is separated therefrom by a barrier layer of a wear resistant and porous material. Connecting ports for connecting the annular chamber respectively to a pulse conduit leading to a pressure measuring device and to a source of a rinsing gas open into the annular chamber.

Abstract: A Venturi tube which is especially suited for the differential pressure measurement of flowing gas/particulate material media with high dust loading at temperatures exceeding 100.degree. C. and at elevated pressures includes a pressure-resistant metallic jacket and an inner lining of wear-resistant porous material which is accommodated in the jacket and bounds a flow-through passage with the Venturi configuration. Respective annular chambers are situated at the inlet region and at the smallest-diameter region of the flow-through passage, there annular chambers being separated from the flow-through passage by respective layers of wear-resistant porous material and being connected by respective pulse conduit with a differential pressure measuring device.
