Embodiment
The utility model is described in detail with reference to Figure of description, it should be noted that of the present utility model
Implementation is not limited to following embodiment.
As shown in figure 1, a kind of two-chamber combustion gas low nitrogen burning machine, including 15, I grades of Gas Pipe 13, II grades of airduct airduct 14, point
Fiery sleeve pipe 3, two level airduct 14 are arranged in one-level airduct 13, and Gas Pipe 15 extend into two level airduct from the afterbody of one-level airduct 13
In 14, igniting sleeve pipe 3 is through in 15, I grades of airducts 13 of Gas Pipe and II grade of airduct 14；In one-level airduct 13 and two level airduct 14
Between solar or lunar halo 8 is installed；Front end shower nozzle 2 is installed in the front end of the one-level airduct 13, in the front end of the two level airduct 14
