오일이용 고온공기 연소시 NOx 저감기술

An Experimental Study on NOx Emission under the High Temperature Air Combustion with Oil

It's well known that with the increase of preheated air temperature NOx is increasing ,while the energy consumption is decreasing. In this study the experimental study was carried out to find out a new method breaking the above-mentioned old concept. From the variation of configuration of gas nozzle and hot test on the temperature distribution and NOx, it was found out that the reduction of NOx was due to the effect of internal gas recirculation, which will be caused by air emitting velocity from burner nozzle.
