Lean-burn is one of the most common low nitrogen combustion techniques. The lean combustion is to divide the flame into two types in order to suppress the generation of NOx, one type is a lean flame in which fuel gas burns under a relatively rich condition and the other type is a lean flame in which fuel gas burns under a relatively lean condition. The principle is that the farther the primary air coefficient deviates from alpha=1 point, the smaller the NOx generation amount, the more the thick flame and the thin flame are combined, and the less the NOx is generated after the thick flame and the thin flame are combined. The rich-lean burner can greatly reduce NOx emission and simultaneously can also stably burn, and the main reasons are the stretching flame stabilizing effect of the rich flame on the lean flame under the flame stretching theory, and the flame stabilizing combustion advantage of the lean combustion as a full premix combustion form; meanwhile, a flame root isolation area is additionally arranged between the thick flame and the thin flame, and the main function is to isolate the lower part of the thin flame from the lower part of the thick flame, so that the overlapping of the thin flame and the thick flame at the position of the flame root is prevented, and the thick and thin combustion effect is lost.
What has been described above is merely a preferred embodiment of the present invention.
