An Experimental Study on Oil Combustion Technology with High Temperature Preheated Air

고온공기이용 오일 연소기술

The objective of this study is to develop a new oil combustion technology concerning industrial furnaces and kilns, not only to save energy but also to reduce environmental emissions. Of many kinds of such technologies we chose the high temperature air combustion technology which was initiated by the British steel company in '80s and developed further by the American burner company "North American". In this study it was carried out to test regenerative burner experimentally and to have an applicability to industry. 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.
