Premixed multi-jet H2/O2 flame reactor was designed after analyzed the principle of H2/O2 flame reactor and disadvantages of tradition auxiliary reactor in this paper. Meantime, flame forms of premixed multi-jet H2/O2 flame reactor were observed by use of “empty model” experiment of heat fluid after combustion. Besides, qualitative discussion was carried out for influence of flame combustion form on temperature and concentration field of reaction zone. Finally, by use of multi-jet H2/O2 flame reactor and use TiCl4 as precursor material, TiO2 nanoparticles were prepared. It was high-temperature hydrolysis of gas phase by controlling process conditions such as TiCl4 concentration, reaction temperature, H2 flow of center loop and second loop. They had uniform particle size from 16 to 34 nm and rutile content 20%. Rutile content was controllable from 9 to 81%.
