저 NOX 연소 방법Low NOX Combustion Method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제 1 도는 본 발명의 연소 방법을 보일러에 적용하는 경우의 보일러 화로(火爐)의 단면도 제 2 도는 제 1 도의 보일러 화로의 측벽(側壁)의 버어너부의 상세 단면도 제 3 도는 제 1 도의 보일러 화로를 사용하여 연소 실험을 행하였을 경우의 부(副) 버어너와 주(主) 버어너의 각 공연비(空燃比)의 비(比)와 배출가스중의 NOX 농도와의 관계를 표시하는 도면 제 4 도는 아프터 버어너를 비치한 본 발명에 의한 보일러 화로 측벽의 버어너부의 단면도 제 5 도는 주버어너와 부 버어너의 한짝을 2단으로 배치하고 또한 아프터 버어너 및 프레임 요동 방지기(frams tabilizer)를 설치한 보일러 화로의 단면도 제 6 도는 제 4 도의 화로에 사용한 프레임 요동 방지기의 부분 상세 단면도1 is a cross-sectional view of a boiler furnace when the combustion method of the present invention is applied to a boiler. FIG. 2 is a detailed cross-sectional view of a burner part of a side wall of the boiler furnace of FIG. FIG. 4 shows the relationship between the ratio of the respective air-fuel ratios of the primary burner and the main burner and the concentration of NOx in the exhaust gas when the combustion experiment is performed using Fig. 5 is a cross-sectional view of the burner section of the sidewall of the boiler furnace according to the present invention having an afterburner. The first and second burners are arranged in two stages. Section 6 of one boiler brazier is a partial detailed cross-sectional view of the frame oscillator used in the furnace of FIG. 4.
