Embodiment 1
[0024] This embodiment takes n=2, m=1 as an example for illustration, as figure 1 As shown, the pneumatic atomizing liquid injector with a wide range of variable working conditions in this embodiment includes a spraying plate 3, grooves are provided on the upper end surface of the spraying plate 3, and each groove forms a first atomizing gas collection chamber 8 respectively. , the fuel collecting chamber 9, the oxidizing agent collecting chamber 10 and the second atomizing gas collecting chamber 11, the first atomizing gas collecting chamber 8 is located at the center of the upper end surface of the injection plate 3, the fuel collecting chamber 9, the oxidant collecting chamber The chamber 10 and the second atomizing gas collecting chamber 11 are annular chambers with the center of the first atomizing gas collecting chamber 8 as the center. In this embodiment, from the outermost circle to the center, there are the second atomized gas collecting chamber 11 , the oxidizing age...
Embodiment 2
[0029] When n>2, it is sufficient to continue to arrange corresponding chambers on the outer ring of the second atomizing gas collecting chamber 11 , and the fuel mist jet and the oxidant mist jet collide at one point through the corresponding atomizing gas nozzles.
