根据作者提出的“充分发挥向火侧一次风着火优势，形成稳定着火源”的燃烧稳定性原理，研制了一种适用于四角燃烧煤粉锅炉的新型燃烧器──调峰型低NOx可调水平浓淡燃烧器。该燃烧器的煤粉浓缩机构及煤粉浓度调节机构简单、可靠。向火侧与背火侧浓度比在1～4的大范围内可调节，保证了锅炉在变负荷工况下实现最佳浓淡比燃烧。工业应用证明：该燃烧器在燃用陕西贫煤时，机组负荷≥50％时不需投油助燃而能稳定燃烧。
According to the combustion stability principle of “giving full play to the advantage of a fire on the fire side to form a steady source of ignition” proposed by the author, a new type of burner suitable for a four-corner pulverized coal fired boiler Adjust the level of light burner. The burner of the pulverized coal concentration mechanism and pulverized coal concentration adjustment mechanism is simple and reliable. To the fire side and the back side of the concentration ratio of 1 to 4 in the large range can be adjusted to ensure that the boiler under varying load conditions to achieve the best shading than burning. Industrial application shows that when the burner burns lean coal in Shaanxi, the unit can be stably burned without oiling and combusting when the unit load is over 50%.
