Abstract (en)
[origin: WO2006074907A1] A device for feeding continuously a system for the pneumatic conveyance of refuse-derived fuels (RDF) constituted by a motorized screw feeder, into which the RDF is fed through a supply hopper; by a diverging conical sealing tube, in which the RDF transferred by the screw feeder accumulates; a chamber for mixing RDF and compressed air, in which there is a fan driven by an electric motor. The compressed air fed to the mixing chamber exits, conveying the RDF, from the pneumatic conveyance tube. The device is inclined at least 30° to allow to fill the conical sealing tube and the taper of a few degrees of the conical tube allows to form a plug of material by virtue of the pressure of the pneumatic conveyance air, thus avoiding unwanted seepage into the feeder hopper. The device therefore allows the regular remote conveyance of the RDF by pneumatic methods.
