Conduit 31 is by putting into suitable packing ring passes dish 4 in the mode of sealing bottom.

As shown in Figure 4, wherein arrow i represents the multiply air-flow of upwards discharging from burner to cause a certain amount of water boiling in burner top (shallow) simultaneously.

When this fuel gas was lighted, flame f distributed on the whole surface of dish, has simulated a hydrocarbon like this and has caught fire.

By changing the relative scale of propane and air, can change the color of flame.

The ratio of 20% air and 80% propane can obtain the flame of reddish yellow form and aspect, is similar to the flame of hydrocarbon.

As index, in the scope of 15～20cm, the thickness of burner 5 is in the scope of 8～15mm the degree of depth of water E greatly in the dish 4, and the degree of depth of burner top water is greatly in the scope of 4～5cm.

But as index, if burner is circular, its diameter for example is approximately 60cm.

Certainly, can select other size, this depends on performed manoeuvre.

This device also is furnished with magnetic valve 18.

Be used for being connected to conduit 16 at some place between pressure switch 13 and magnetic valve 14 to the propane supplying duct 17 of igniter 70 supplying propanes.

Before manoeuvre begins, use device 70 will made an inventory.

Air blast 2 is connected, and all propane supply valves are opened, like this:

-admixture of gas supplies to burner 5 (Fig. 1, arrow M) by conduit 31;

-propane supplies to device 7 (Fig. 1, arrow P ') by conduit 17 and nozzle 730; With

-air supplies to device 7 (Fig. 1, arrow A ') by conduit 22 and nozzle 720.

Mist M discharges from burner with the form of the little jet i of air of the ejection that directly makes progress, and the water E in the feasible dish 4 of the little jet of these air produces boiling to a certain degree.

The air and the propane stream that arrive compression in the ducted body 70 are mixed therein, and with respect to the minor diameter of described pipe, resulting mist is blown in the pipe 78 with higher flow velocity.

In the larger-diameter end 780 of described pipe, gas stream expands and speed slows down.

By closed contactor 610, to supply with electric current to spark plug, thereby produce spark at the tip of electrode 62, its tip is positioned at described part 780 inside, is in the center of burning mixture.

This causes mist to be lighted, and the mist of burning spreads in conduit 71 inside, and from then on discharges by reclinate part 710, and by reclinate part 710, the mist of burning points to the water surface of burner 5 tops.

Because burning mixture also emits from described burner, so burning is transmitted in the dish.

A kind of Monitoring and Controlling circuit is provided, and with mark 80 expressions, for example a kind of microprocessor is used for monitoring and controlling this device in Fig. 5.

With the programming of Monitoring and Controlling circuit, under safest state, carry out to guarantee manoeuvre.

As long as sensor 8c detects in the pipe-type outlet 71 and has flame, described circuit 80 will control contactor 610, so that supply to the power-off of spark plug 6.

As long as sensor 8a, 8b detect and have flame in the dish, described circuit will shut off valve 18.

Because ignition system is inoperative, so the burning in the conduit 71 can stop with that.

The training exercise that is used for elimination dish moderate heat just can begin.

The existence of dish top conduit 71 can not hinder the carrying out of manoeuvre by any way.

For horizontal plane in the holding tray constant (burner top), and fall unnecessary water (because the adding firing-fighting medium causes), also can preferably provide a kind of overflow mechanism (not shown) for equilibrium.

On the contrary, also can add a kind of water and fill it up with device, to compensate the loss of the water that causes owing to evaporation.

These two kinds of devices can be merged together and form a kind of water circle device, and this device has water level control and selectively is furnished with a filter.

From the line map of Fig. 5 as can be seen, the information that receives from transmitting of circuit 80 with lower device:

-ultraviolet radiation detector 8a, 8b, 8c and sensor 8d;

-be used to survey the detection circuit 9 of the intensity of anomaly of propane in the area L that fences up or carbon monoxide; And

-hygrosensor 93.

Circuit is programmed for control contactor 610, with the igniting of control electrode, magnetic valve 14 and 18 and fan 92 all control with preset program.

Microprocessor 80 is certainly controlled according to wish, for example, by computer keyboard control, with various operational factors and operation-monitoring parameter input microprocessor, and starts and finish manoeuvre.

In the maneuver period, the trainee must make great efforts to utilize the fire extinguisher of existing adequate types that the flame that the scene of a fire causes is put out.

Utilize range detector 8a, 8b to survey the existence of effective flame continuously.Certainly, if the more complicated that manoeuvre is made can provide plural this detector.

When detector was again surveyed less than flame, fire extinguishing was considered to gratifying, and this just impels the trainee wholeheartedly.

Enough coolings in the scene of a fire also can cause stopping working, and this is detected by sensor 8d, and this sensor has been considered the real time temperature measurement.

Under two kinds of situations, circuit can make magnetic valve 14 close in the above, thereby stops propane to arrive the scene of a fire.

Air can continue to arrive, and this is not insoluble problem.Outside the air of being carried by air blast also can directly lead by valve 21.

Should be appreciated that in the whole operation process, electrode and is subjected to the protection of conduit 71 not in the medium scope that is used to put out a fire, and is not subjected to because the moisture that the water E of boiling is caused in the dish 4 and the influence of water smoke.

Therefore, electrode still can be used for new manoeuvre, and new manoeuvre can repeat in the same manner as described above at once.

Preferably, circuit 80 is programmed for, if through (for example after one minute) after certain preset time, the trainee does not also extinguish the blaze, and still starts magnetic valve 14, supplies with to cut off propane, and therefore automatic fire with the scene of a fire extinguishes.

If detect propane arranged in the area L that fences up (for example owing to leak or loss of ignition causes) by sensor 90, if perhaps detect the horizontal abnormality of carbon monoxide by sensor 91, circuit 80 is connected fan 92 so, thereby by magnetic valve 14 cutting out remove those pernicious gases in the zone, and cut off the supply of propane.

If temperature occurs unusual, this may be that temperature sensor 93 also can cut out magnetic valve 14 because out of control igniting causes, and supplies with thereby cut off to the propane of burner.

A plurality of scenes of a fire of the present invention certainly are provided in identical zone, and each scene of a fire can completely or partially be supplied with by the propane 1 of identical bottle and/or identical air blast 2.

Each sensor 8,90,91 and 93 number and position are suitable for the configuration of mating area and the position in each scene of a fire certainly.

As mentioned above, can be by changing flame detector 8a, the number of 8b and the difficulty that the angle position changes manoeuvre.

Should be appreciated that, if shell 7 place away from any danger, just can the environment for use air as the oxidant that is used to light.For this purpose, remove conduit 22, the air intake air vent 76-77 and 76 '-77 ' of air by regulating suitably 76 enters in the shell 7 by entering the mouth then.The gas of compression enters into ducted body 72 and will produce enough negative pressure, makes air be inhaled into wherein.

The proper proportion of fuel gas and oxidant air can utilize cam bit 75 to regulate, and when feasible, also can regulate by closable air vent 76-77 and 76 '-77 '.

This device can be provided in the fixing or movable zone, for example, above described in the described file EP-0145 465 on the truck of type.
