Embodiment 1
[0027] refer to figure 1 , figure 2 , image 3 and Figure 4 , a plasma oil-free ignition staged burner of the present invention, including a plasma generator 1 and a burner 2. Two sets of guide vane sets 3 are arranged in the burner 2, the guide vane sets 3 include four guide vanes 5, there are gaps between the guide vanes 5, the guide vanes are arc-shaped, the radius of curvature is the same as the radius of curvature of the burner nozzle Similarly, the center of arc of the guide vane 5 is inside the burner, and the guide vane 5 is connected with a movable guide rod 4 . The guide vane set 3 and the combustor 2 are coaxially arranged. like figure 2 As shown, the movable guide rod 4 radially penetrates into the burner 2, and can drive the radial movement of the guide vane 5, and the radial movement is a linear reciprocating movement.
[0028] Before ignition, such as image 3 As shown, the guide vanes 5 are retracted and attached to the inner wall of the burner. When...
Embodiment 2
[0032] refer to figure 1 , Figure 4 , Figure 5 and Image 6 , the difference between this embodiment and Embodiment 1 is that in this embodiment, the guide vane group 3 includes 6 pulverized coal air flow guide vanes 5, the radius of curvature of the guide vanes 5 is the same as that of the burner nozzle, and the guide vanes 5 arc The center of the surface is inside the burner, and each pulverized coal flow guide vane 5 is inserted into the burner 2 in a circular arc reciprocating motion with a certain center point 6 as the center of the circle (the center point 6 is the rotation center of the blade 5). The vane group 3 can divide the pulverized coal flow into two parts (or approximately into two parts). The plasma generator 1 is axially inserted into the space surrounded by the guide vane set 3, ignites the pulverized coal flow entering the space, and forms a new, stable ignition source with higher thermal power at the outlet of the guide vane set 3 end , using this ign...
Embodiment 3
[0036] refer to Figure 7 , Figure 8 and Figure 9 , the difference between this embodiment and Embodiment 1 is that in this embodiment, the guide vane group 3 includes 5 pulverized coal flow guide vanes 5, the radius of curvature of the guide vanes 5 is the same as that of the burner nozzle, and the guide vanes 5 arc The center of the circle of the surface is outside the burner, the movable guide rod 4 pushes the guide vane group 3 into the burner axially from the burner, and the guide vane group 3 can also be axially withdrawn from the burner through the movable guide rod 4, that is, the guide vane 3 from axial ( Figure 9 Insert or withdraw the burner in the vertical direction of the paper. The vane group 3 can divide the pulverized coal flow into two parts (or approximately into two parts). The plasma generator 1 is axially inserted into the space surrounded by the blade group 3, ignites the pulverized coal flow entering the space, and forms a new, stable, and higher ...
