연소공기를 2단으로 나누어서 공급하고, 1단째 환원분위기에서 연소되고, 2단째의 공기와 자기 재순환가스를 원주위에 번가라 배열하여 공급하므로서 원심력(遠心的)으로 확산하는 1단째의 고리모양의 환원분위기를 포위하여 조(條)형상 산화염(酸化炎)영역과 조형상 환원염 영역을 교대로 구성하여 분할화염을 형성하도록 하고 상기 조형상 산화염 영역의 연소의 말기에는 잔존하는 공기는 환원염 영역으로 확산하고 3단째의 완만한 연소를 완료하며, 그 말기에는 고리형상의 화염은 차차로 관성을 상실하고 감속하는 동시에 일부는 화염의 외주부로 부터 버너 순환흡입구로 환류하고, 일부는 화염의 중심부에 생긴 부압부(負壓部)로 유입되는 순환류로 되도록 한저 NOx버너.The first stage ring-shaped reduction is supplied by dividing the combustion air into two stages and burning in the first stage atmosphere, and supplying the second stage air and the self-recirculating gas alternately around the circumference. Surrounding the atmosphere, the crude oxidized salt zone and the crude reduced salt zone are alternately formed to form a split flame. At the end of combustion of the crude oxidized salt zone, the remaining air diffuses into the reduced salt zone. At the end of the third stage, the combustion of the annular flame gradually loses inertia and decelerates, and at the same time, some flows back from the outer periphery of the flame to the burner circulation inlet, and some of the negative pressure is generated at the center of the flame. Hanzo NOx burner to be a circulating flow flowing into the back. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
