Next, with reference to FIG. 1, a first embodiment of the flame injection device according to the present invention will be described.
In FIG. 1, parts corresponding to those in FIG.
In the first embodiment of the flame injection device M according to the present invention, the fuel F is supplied from the fuel source (not shown) through the fuel pipe 12 as in the case of the conventional flame injection device M described above with reference to FIG. The flame injector 11 is provided with a flame injector 11 mounted at the front end thereof and a blower (not shown) for sending out an oxygen-containing gas G made of oxygen or a gas containing oxygen. 11, a blower pipe 21 concentrically extending forward with the axis of the flame injection nozzle 13, a through hole and a circular disk shape, and the flame injection nozzle 13 of the flame injector 11. And a wind-cut plate arranged concentrically with the axis of the flame injection nozzle 13 so as to be orthogonal to the axis of the flame injection nozzle 13 at a fifth position P5 in the vicinity of the tip of the gas. The oxygen-containing gas G is introduced into the blower pipe 21 in an air current state. By supplying the fuel F from the fuel source to the flame injector 11 through the fuel pipe 12 in a state where the oxygen-containing gas G is sent forward through the blower pipe 21 and the wind cut plate 41. The fuel F is ejected from the fuel injection nozzle 13 of the flame injector 11 into a sprayed state, and the fuel F in the sprayed state is ignited. The flame B, which is composed of the high-temperature outer flame b2 and has a shape that greatly expands toward the front, is injected, and the position of the extended end of the blower pipe 21 is set to the flame injection nozzle 13 of the flame injector 11. The third position P3 between the first position P1 at the tip of the flame B1 and the second position P2 at the tip of the inner flame b1 of the flame B injected from the flame injection nozzle 13 is set as the third position P3. nozzle 3 and the outer diameter at the second position P2 of the tip of the inner flame b1 of the flame B injected from the flame injection nozzle 13 is set to the first position P1 of the tip of the third pipe. It has a configuration in which the diameter φ2 is larger than φ1 and the fifth position P5 of the wind cutting plate 41 is located behind the first position P1 of the tip of the flame injection nozzle 13.
Further, the first embodiment of the flame injection device M according to the present invention has the above-described configuration, and the blower pipe 21 in the first position P1 of the tip of the flame injection nozzle 13 and the fifth position P5 of the wind-cut plate 41 is provided. The fourth position P4 between the sixth position (not shown) near the tip of the flame B and the second position P2 of the tip of the inner flame b1 of the flame B is set to the fourth position P4. An outer diameter that is larger than the outer diameter (not shown) at the fourth position P4 but smaller than the diameter φ2 of the tip opening of the blower pipe 21 and smaller than the diameter φ2 of the tip opening of the blower pipe 21 An annular plate 31 for generating a turbulent vortex flow having a diameter φ4 is arranged concentrically with the flame B with its plate surface lying on a plane perpendicular to the axis of the flame B.
The above is the configuration of the first embodiment of the flame injection device M according to the present invention.
According to the embodiment of the flame injection device M of the present invention having such a configuration, as in the case of the conventional flame injection device M described above with reference to FIG. In a state where the position P3 is the first position P1 at the tip of the flame injection nozzle 13 of the flame injector 11, adjustment of the injection amount and injection speed of the fuel F in the spray state from the flame injection nozzle 13 in the flame injector 11 By adjusting the flow rate and flow rate of the oxygen-containing gas G from the fuel source to the fuel pipe 12 and adjusting the diameter φ2 that is the diameter of the opening at the extended end of the blower pipe 21 as a pre-adjustment, flame injection By adjusting the shape and temperature of the flame B injected from the flame injection nozzle 13 of the vessel 11 in advance, it can be widely used, for example, as the flame injection device M itself or for boilers.
By the way, in the case of the first embodiment of the flame injection device M according to the present invention, it is close to the tip of the blow pipe 21 in the first position P1 of the tip of the flame injection nozzle 13 and the fifth position P5 of the wind-cut plate 41. A position from the sixth position to the second position P2 of the tip of the inner flame b1 of the flame B is defined as a fourth position P4, and the turbulent flow generating annular plate 31 is disposed at the fourth position P4. Therefore, the oxygen-containing gas G to be sent forward through the blower tube 21 and the wind cut plate 41 is blocked by the plate portion 32 of the turbulent vortex generating annular plate 31, and the turbulent vortex generating annular ring. Between the inner surface of the hole 33 forming the inner diameter φ3 of the plate 31 and the outer peripheral surface of the flame injection nozzle 13 of the flame injector 11, the outer peripheral surface of the turbulent flow generating annular plate 31 and the inner surface of the blower tube 21 Pass through. For this reason, the negative pressure of the oxygen-containing gas G is generated in front of the back surface side of the turbulent flow generating annular plate 31, and thus the oxygen-containing gas G is the first position P <b> 1 that is the position of the tip of the flame injection nozzle 13. The oxygen-containing gas G that is sent forward as turbulent vortex E in front of the back side of the turbulent vortex generating annular plate 31 that is further forward, and thus becomes turbulent vortex E, is flame. It acts with the fuel F in the spray state injected from the flame injection nozzle 13 of the injector 11.
Incidentally, in the case of the conventional flame injection device M described above with reference to FIG. 22, since the turbulent flow generating annular plate 31 is not disposed, the oxygen-containing gas G is the position of the tip of the flame injection nozzle 13. In front of the position P 1, the turbulent vortex flow is sent forward as a steady flow that is not turbulent, and such a steady flow of oxygen-containing gas G is injected from the flame injection nozzle 13 of the flame injector 11. It only works with the sprayed fuel F.
From the above, in the case of the first embodiment of the flame injection device according to the present invention, the oxygen-containing gas G is used for generating turbulent flow to the fuel F in the spray state injected from the flame injection nozzle 13 of the flame injector 11. This is more effective than the conventional flame injection device M described above with reference to FIG. 22 in which the annular plate 31 is not disposed.
For this reason, the fuel F in the spray state injected from the flame injection nozzle 13 hardly remains or remains in the flame B injected from the flame injection nozzle 13 in a state where it does not become the flame B but is mixed as unburned fuel. However, there is much less remaining than in the case of the conventional flame injection device M described above with reference to FIG. 22, and the fuel F hardly scatters from the flame B to the outside of the flame B as unburned fuel. However, even if it is scattered, it scatters much less than in the case of the conventional flame injection device M described above with reference to FIG. 22, and therefore, in the case of the conventional flame injection device M described above with reference to FIG. In comparison, the fuel F can be burned with high efficacy and the flame B can be injected at a high temperature.
