1,141,888. Making fuel gas. BADISCHE ANILIN- & SODA-FABRIK A.G. 17 June, 1966 [18 June, 1965], No. 27161/66. Heading C5E. An apparatus for mixing gaseous and vaporous hydrocarbons with air or oxygen, optionally with steam, for flameless catalytic partial combustion reactions, comprises inner and outer tubes 1, 7 respectively, a spindle 2 in the tube 1 carrying guide blades 3 and a member 4, and a mechanism 5 connected to the spindle 2 for axial adjustment thereof to enable the member 4 to regulate the outlet cross-section of the tube 1. The mechanism 5 may be automatically controlled, e.g. by a device 9 responsive to the pressure difference across the tubes 1, 7. Hydrocarbon is delivered by the tube 7, and air &c., with or without steam, by the tube 1, the amount of air &c. being thus controlled to match the richness of the hydrocarbon. The tubes 1, 7 lead to a diffuser 8 which communicates with a catalyst chamber.
