Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates generally to fire fighting training equipment. And in particular, the present invention relates to a fire fighting training device having a liquid propane burner system and having a diffuser utilizing a diffusion medium, such as water or other gravel.

2. Description of the Related Art A conventional fire extinguishing training device is 1989
It is described in U.S. Pat. No. 4,861,270, which was granted a patent on Aug. 29, 1996 and is assigned to the same assignee as the present specification.

Prior art fire fighting training devices include a burner system and a support for the burner system. The burner system includes a discharge pipe having a hole for injecting propane to create a flame, a control unit connected to the discharge pipe, a igniter unit for igniting the injected propane to create a flame, and a discharge pipe. And a ignition unit for igniting the injected propane. One prior art system uses pressurized propane gas. Another prior art system uses pressurized liquid propane.

[0004]

One problem with prior art systems using pressurized liquid propane is that the pressurized propane is generated by injecting pressurized liquid propane from a discharge pipe into a propane vapor. The point is that it is relatively difficult to ignite and control the steam. Another problem is that the flame near the emission in the prior art is
The point is that when a liquid fuel such as combustion of gasoline, oil or jet fuel is scattered, it does not look like a flame.

[0005]

A fire fighting training device is provided by the present invention. This training device comprises a burner system, a diffuser and a support for them, the burner system having a discharge pipe with a hole for ejecting liquid propane, and a starter connected to the discharge pipe. A control unit having a unit, the diffuser having an open tank, and the discharge pipe having a quantity of water or other medium contained therein which is submerged therein.

By using an open tank with large amounts of water or other medium in which the discharge pipe is submerged, the difficulty of igniting and controlling propane vapor is minimized. Also, the flame of propane vapor takes on the appearance of a flame when liquid fuel is sprinkled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIGS. 1 and 2, a fire fighting training device 10 is provided, which comprises a diffuser 11, a burner system 12 and a support 20. The diffuser 11 has an aboveground water tank or open tank 21, and in this embodiment a large amount of water 22 is contained in the tank 21.

The burner system 12 has a lateral liquid fuel or pressurized liquid propane discharge pipe 23. pipe
23 has a plurality of holes 24. Burner system 12 also includes an igniter or igniter 25 that provides igniter 26.
The pipe 23 has a pressurized liquid propane 27 which is jetted or shot into the water 22. There, the liquid propane 27 suddenly transforms into propane vapor 28, which diffuses through the water 22 as bubbles of propane vapor. The propane vapor 28 forms a flame on the fire 29 and is placed on the surface of the water.

Burner system 12 also includes a control or valve unit 30. The control unit 30 has a line 31 connected to the lateral pipe 23. The control unit 30 is also connected to the supply line 32. The igniter device 25 also has a igniter line 33 connected to a suitable gas source (not shown). Firefighters 34,35 as shown in FIG.
Use to extinguish the fire 29. The tank 21 is made of steel or other suitable refractory material. Support 20 is made of concrete or other suitable material. Pipe 23,31,32,3
3 is made of metallic material.

In operation, when the liquid propane is subjected to pressure and directed to the propane discharge pipe 23, the liquid propane 27 is jetted out of the hole 24 of the pipe 23 and suddenly changes into gas,
It diffuses through the water 22 as bubbles of gas 28. Propane vapor
When 28 reaches the surface 22 of the water, it creates a flame 29 that is ignited by the igniter 26 and burns on the surface of the water. Flame 29
The size of can be changed from a relatively small size to a large size by the control unit 30 that regulates the flow velocity. The controller 30 can be used to instantly interrupt the flow of liquid propane in an emergency.

In summary, the training device 10 has an open water tank 21 and a propane discharge pipe 23 installed below the surface of the water 22. The pipe 23 has a hole 24 drilled along its submerged length. When liquid propane is directed into the discharge pipe 23 and out through the hole 24, it suddenly transforms into propane vapor and diffuses through the vicinity of the pipe 23 into the water 22. Propane vapor rises to the surface,
When ignited by the previously identified ignition 26, it burns on the surface of the water 22 in the form of a sprinkled liquid fuel such as petroleum, gasoline or jet fuel.

The training device 10 may use clean-burning propane as fuel within the device to train the firefighters 34,35. The training device 10 avoids the need for burning oil or jet fuel that produces relatively large amounts of pollutants that prior art training devices have. The advantages of the training device 10 are shown below.

A) The training device 10 uses liquid propane to train firefighters in extinguishing a relatively large fire that can be compared to a fire when fuel is sprinkled or a fire caused by a plane crash. B) The training device 10 produces a controlled, simulated fire that can be compared to an actual burning liquid fire.

While the invention is described in its preferred embodiments, the words that have been used are words of description rather than of limitation, and variations are a true version of the invention in its broader aspects. It should be understood that it can be made within the scope of the appended claims without departing from the scope and intent. For example, the tank 21 can be installed in the soil instead of on the ground. As another example, tank 21 may utilize other diffusion media instead of water, such as gravel. Another example is a pipe
23, 31, 32 can be made of plastic material instead of metal material. As yet another example, the ignition device 25 may be an electric ignition device instead of the igniter device. Further by way of example, the training device 10 may include a security monitor and sensing device or the like. Still further by way of example, the pipe 23 can have different configurations. Also, multiple juxtaposed open tanks can be used instead of a single tank 21.
