Abstract (en)
[origin: WO2009146935A2] The invention relates to a method and a device for feeding conveyable materials to reaction furnaces by means of a hollow space that feeds into the furnace space by way of a connecting tube, said hollow space being sealed air-tight from the exterior air. A tube configured as a lance (6) is fed from the hollow space, which is sealed air-tight from the exterior air, into the furnace space (7), said tube having a cross-sectional area that is less than the conveying line connected upstream, wherein an air or gas stream flows into the furnace space (7) from the region of the hollow space upstream of the lance, said space being sealed air-tight from the exterior air, and is conveyed into the starting region of the lance by way of a mechanical conveyor (5, 15) operating at zero pressure.
