Device for providing and feeding a burner feed consisting of non-torrefied fibrous carbonaceous feedstocks for pressurized entrained flow carburetors

Abstract

Device for processing non-torrefied fibrous carbonaceous feedstocks into a burner feed for a zip-flow gasifier, comprising a mechanical grinding and classifying device, wherein the grinding and classifying device is upstream of a pressure inlet and burner feed device of the zip-flow gasifier and is configured to mechanically grind and classify the feedstocks without prior torrefaction, wherein the grinding and classifying device has a classifying or separating device for limiting, separating, removing or recirculating oversized, long-fibered, splinter-shaped, needle-shaped, foil-like or agglomerated components, so that a burner feed with a limited coarse fraction and a limited proportion of elongated or fibrous contaminants can be provided, and wherein the burner feed can be fed to the pressure inlet and burner feed device and is suitable for pressure inlet,Suitable for conveying with high solids loading and burner input into the pressurized entrained flow carburetor.
