Abstract
A burner device for use inter alia in the preparation of finely-divided metal oxides by the method of Specification 1,047,713, comprises a metallic tubular pre-combustion chamber of which one end is in open communication with a metallic, tubular mixing chamber and having a common axis therewith, the end of the pre-combustion chamber furthest from the mxing chamber having a centrally located inlet conduit directed axially into the pre-combustion chamber and at least one annular orifice surrounding said inlet conduit, for feeding separately to the pre-combustion chamber a free oxygen-containing gas and a combustible gas, a plurality of conduits of small diameter opening radially into said mixing chamber for feeding a mixture of metal chloride vapour and oxygen to the mixing chamber, and means for contacting the exterior of the pre-combustion chamber and mixing chamber with a cooling fluid. In Fig. 1, for example, oxygen is passed into a pre-combustion chamber C through inlets g1 and g2 passing fins h2. Carbon monoxide or other inflammable gas is passed into C through inlet k1 <PICT:1047714/C1/1> passing fins k2 and k3. Nitrogen may pass through l1 into C. The gases are ignited and the burnt gases violently directed into mixing chamber D where they meet jets of, for example, titanium tetrachloride and excess oxygen from m4 and m5 and similar peripheral inlets, which mixture has been introduced at m1 and passed through pipes thermally insulated from the cooling fluid e.g. oil or water, entering at n1 and leaving at n2. The reaction forming the oxide starts in the burner and is carried to completion in the oxidation furnace. The burner may be of aluminium. Chambers C and D may form a Venturi tube with inlets m4 and m5 at the neck. Modifiers such as steam may be added to the oxidizing gas or the monoxide, or chlorides, such as aluminium or silicon chloride may be added to the stream of volatilized chloride. Oxides of titanium, zirconium, aluminium, tin, chromium, iron, silicon, hafnium and niobium may be made in the burner.
