[0033] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0034] Working principle of this utility model:
[0035] The gas enters the gas pipeline 1 through the gas input pipeline 2 of the first gas combustion zone, and is ejected from the gas burner 3 and ignited by the ignition needle 4. When the temperature monitored by the temperature controller rises to the set value, the ignition of the first gas combustion zone is completed; the gas enters the gas pipeline 1 through the gas input pipeline 2 of the second gas combustion zone, and is ejected from the gas burner 3 and ignited by the ignition needle 4. When the temperature monitored by the temperature controller rises to the set value, the ignition of the second gas combustion zone is completed; the gas enters the gas pipeline 1 through the gas input pipeline 2 of the third gas combustion zone, and is ejected from the gas burner 3 and ignited by the ignition needle 4. When the temperature monitored by the temperature controller rises to the set value, the ignition of the third gas combustion zone is completed. At this time, all three gas combustion zones are ignited, forming a low-fire combustion state;
[0036] The gas enters the main gas pipeline 5 through the main gas input pipeline 6 of the aviation kerosene combustion zone, and is ejected from the main gas burner 7 and ignited by the main ignition needle 8. At this time, the aviation kerosene is transported to the medium-fire kerosene nozzle 10 through the medium-fire kerosene input pipeline 9. At the same time, the pressurized air is also transported to the medium-fire kerosene nozzle 10 through the medium-fire pressurized air pipeline 11, so that the aviation kerosene is ejected under the pressure of the pressurized air and ignited by the burning flame. When the temperature of the aviation kerosene combustion monitored by the temperature controller rises to the set value, the ignition is completed, forming a medium-fire combustion state;
[0037] Aviation kerosene is delivered to the high-fire kerosene nozzle 13 through the high-fire kerosene input pipe 12. At the same time, the pressurized air is also delivered to the high-fire kerosene nozzle 13 through the high-fire pressurized air pipe 14, so that the aviation kerosene is sprayed out under the pressure of the pressurized air and ignited by the burning flame. When the temperature controller monitors that the temperature of the aviation kerosene combustion rises to the set value, the ignition is completed and a high-fire combustion state is formed.
[0038] When conducting engine fuel flow combustion fire extinguishing training, use a fire hydrant special nozzle to spray water on the fire point. When the water is sprayed on the flame, the flame temperature drops. When the temperature drops to the high fire extinguishing setting value, the high fire is extinguished; when the temperature drops again to the medium fire extinguishing setting value, the medium fire is extinguished; when the temperature drops again to the low fire extinguishing setting value, the low fire is extinguished; at this time, all flames are extinguished, and the fire fighting training is completed.
[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
