Example Embodiment
[0027]Example 1: Such asfigure 1 As shown, the direction of X in the figure is the axial direction described in this embodiment, and is also the front-to-rear direction, and the direction in which the Z-axis in the figure extends is the radial direction described in this embodiment, which is also a top-down direction. , The Y-axis in the figure is the horizontal direction described in this embodiment, and it is also a left-to-right direction. The horizontal direction in this embodiment is a direction parallel to the plane formed by the XY axis. The vertical direction of is the direction parallel to the plane formed by the ZY axis.
[0028]Such asfigure 1 withfigure 2 As shown, the thin-film evaporative flame stabilizer of the present invention includes a cavity flame stabilizer 1 and a horizontally extending first splitter plate 2 arranged at the front end of the cavity flame stabilizer 1. The cavity flame stabilizer 1 includes a vertical upward extension The front edge plate 11 of the...
Example Embodiment
[0033]Example 2: Such asFigure 6 As shown, the thin-film evaporative flame stabilizer of embodiment 1 is applied to a rectangular combustion chamber, the ignition nozzle 7 of the combustion chamber opens on the main board 12, and the trailing edge of the liquid film covering plate 4 preferably does not exceed the opening of the ignition nozzle 7 position. The cavity flame stabilizer 1, the first splitter plate 2 and the second splitter plate 8 are fixedly connected to the side walls of the rectangular combustion chamber 9 through two side surfaces; the upper end surface of the supporting plate flame stabilizer 3 is fixedly connected to the front splitter plate 4, supporting The lower end surface of the plate flame stabilizer 3 is fixedly connected to the lower wall surface of the rectangular combustion chamber 9. The supporting plate flame stabilizer 3 is a thin-walled hollow piece, the outer shell 32 forms a triangular bluff body structure, and the ignition nozzle 7 is welded or me...
