本燃烧器 (专利号 :ZL0 1 2 0 1 75 6 0 )应用于电站切圆燃烧的煤粉锅炉上 ,取代原来的直流煤粉燃烧器。该燃料器将原喷口分成 3个动量相差悬殊的小喷口 ,通过大动量喷口喷出气流的强烈卷吸作用 ,使小动量气流在喷口外速度不断降低甚至滞止 ,其携带的煤粉颗粒由于惯性作用在喷?
The burner (patent number: ZL012107560) used in power plant tangentially fired pulverized coal boiler to replace the original DC pulverized coal burner. The fuel injector divides the original spout into three small spouts with a great difference in momentum. The strong scrolling effect of the spouting airflow through the large spout causes the small momentum stream to continuously decrease or even stagnate outside the spout. The pulverized coal particles carried by the fuel Inertia effect in the spray?
