Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulated fire generating device for fire fighting training products.

[0002]

2. Description of the Related Art FIG. 14 shows a conventional example of a simulated fire generating device for fire fighting training products. A fuel pipe 2 having a burner 1 for generating a flame is installed in the device, and an extinguishant container 3 for collecting the extinguishant is installed under the pipe 2. An extinguishant detection sensor 4 for detecting the amount of the extinguishant is attached to the side of the receiving box 3. Reference numeral 6 is a fuel tank, 5 is a fuel source valve, and 8 is a control panel which receives the detection signal from the extinguishing agent detection sensor 4 and opens and closes the fuel source valve 5 based on the detection signal.

In the simulated fire generating apparatus configured as described above, when a simulated fire occurs, the fuel source valve 5 is opened to send the fuel contained in the fuel tank 6 to the burner 1 and the igniter 7 Then, a flame is generated by igniting this fuel. On the other hand, when the extinguishant enters the collection box 3 for recovery, the sensor 4 detects the amount of the extinguishant,
The flame is suppressed by closing the fuel source valve 5 as necessary.

[0004]

However, the above-mentioned conventional simulated fire generating device has the following problems.

(1) Burner 1 for combustion and fuel pipe 2
However, the receiving box 3 for collecting the extinguishant and the extinguishant detection sensor 4
In this model, the extinguishant will fall on the burner 1 for combustion and the fuel pipe 2 since it is arranged immediately above. During combustion of fuel, the temperature of the combustion furnace becomes high, but if a large amount of cold extinguishant suddenly falls on this high temperature part, it will be cooled. When such an action is repeated, the burner portion such as the burner 1 is heated and cooled to cause thermal fatigue, and durability and safety are significantly impaired.

(2) Since the above-mentioned simulated fire generator is often installed indoors, the fuel needs to be cleanly burned without soot after burning. The flame color changes from red to blue as the clean combustion is performed, that is, as the combustion is almost complete. Therefore, there is a contradiction that the difference from the color at the time of the actual fire becomes large.

An object of the present invention is to prevent the extinguishant from falling on equipment such as a combustion device during fire extinguishing work, thereby preventing deterioration of durability of the combustion device and the like.
It is an object of the present invention to provide a simulated fire generating device that has no difference in color from an actual fire flame and that can obtain flames of various colors.
