摘要
在单元体层燃炉模型炉上,对采用空气分级燃烧技术前后的燃料层温度、烟气中的CO、O2、NOx浓度进行了试验研究。采用分级燃烧技术后,点火时间缩短,燃烧剧烈区出现较晚,CO和O2浓度降低,有利于可燃气体的燃尽,减少了主燃烧区NOx的排放。
With a fixed-grate furnace model, the temperature of fuel layer and the concentration of CO, O2 and NOx in flue gas were studied respectively before and after application of the air-staged combustion technology. Shortened ignition time, delayed appearance of violent combustion and reduced concentration of CO and O2 were attained after the technology was adopted, which were all profitable for burn out of combustible gases. In addition, a reduction of about 20 % NOx emission was obtained.
