An oxygen-containing gas is heated to a temperature between 1,200 DEG C. and 1,800 DEG C. to be used in oxidizing titanium Chloride to titanium dioxide. The oxygen-containing gas is first preheated by known means above the ignition temperature of a fuel used in a burner apparatus having a fuel nozzle. The oxygen-containing gas is then passed rectilinearly around the nozzle between 350 and 1,000 feet per second thereby preventing flame eddies. The oxygen-containing gas is commingled with fuel distributed by the nozzle in a combustion zone resulting in an elevation of the gas temperature and is then transferred to a reaction zone where the oxidation process takes place.
