Abstract

950,345. Oxidizing carbonaceous material in gaseous suspension. BADISCHE ANILIN- & SODA-FABRIK A.G. Oct. 31, 1961 [Nov. 4, 1960], No. 38864/61. Heading B1X. [Also in Division F4] Carbonaceous material in suspension in an oxidant-resistant liquid is oxidized in a chamber wherein the liquid is evaporated by the combustion of auxiliary fuel and the material is mixed with an oxygen-containing gas stream by an orifice plate. A slurry of carbon black in water is delivered to a combustion chamber 1 through an atomizer 8. Air and fuel are supplied tangentially at 9, 10 to burn in a chamber 7 surrounding the atomizer 8 and entrain the slurry in a whirling stream of hot gases. Additional air or oxygen introduced at 15, 16 cools the chamber walls and the carbon black burns in a ring of flame above an orifice plate 11 which causes the intimate mixing of the gases so that combustion is completed in a chamber 3. The chamber 3 discharges tangentially to a cylindrical separator 4 and the gases are fed to a heat exchanger 13 to preheat air or fuel, and used to concentrate the aqueous slurry in a vessel 5. A condenser 6 allows the liquid to be recovered.
