This paper discribes a convenient system for preparation of zinc oxide nano particles by water solution combustion method . This system consists of three main parts: injection control system, combustion chamber, and cold surface collector, respectively. The most important control parameters such as flow rate of heat combustion gas and raw material solution, injection back pressure, and temperature of cold collector can be easily controlled in this system . we ran combustion tests for solution combustion and emulsion combustion method (ECM) in preparation of zinc oxide nano particles; and it was found that this system was more efficient in solution combustion method specially in water based solution combustion than ECM in preparation of zinc oxide nano particles.
