Abstract

The invention relates to a technology for pressurizing dust. The dust is fed from a storage hopper of a feeding device, the storage hopper being at ambient pressure. In the feeding device, the dust is pressurized by introducing high-pressure inert gas and fed to a high-pressure apparatus. By means of a hydraulically deflected membrane in the feeding device, the remaining volume to be relaxed after the dust sluicing and the consumption of inert gas are minimized.
