NL1033701C1 - Fire simulator for training purposes, includes extinguisher detection system and smouldering fire simulating structure - Google Patents

Abstract

The simulator (1) includes a smouldering fire structure (2) comprising an arrangement of round or rectilinear structures (6) covered with heat resistant metal gauze, which are heated from the inside so that they glow red hot. A fireplace (13) is located beneath these structures and an extinguisher detection system (12) is also provided in the simulator. The fireplace and burners (3) for the smouldering fire can be controlled independently.

Description

Title: Smeulbrand Simulator

The invention relates to a fire simulator for use during training in the context of fire fighting.

The Smeulbrand simulator is used to simulate a solid fire that has not been extinguished sufficiently. This keeps the solids so warm that they continue to glow or smolder. This can result in re-ignition. The combination of the smoldering fire integrated into other fire simulators and linked to an operating system with which various scenarios can be completed is unique. By scenario is meant: a succession of events in which a sea of flames 10 (gas-fired or with another fuel), after extinguishing, changes into the smoldering effect. This smoldering effect is realized by the Smeulbrand simulator. The intensity, duration and degree of difficulty of extinguishing the smoldering fire can be adjusted in specially designed software. The sea of flames can also re-ignite after "bad" extinguishing.

The invention relates to a training unit for training in fire fighting, comprising at least one fire simulator 1 consisting of glowing structures 2 placed above a firebox 13.

This smoldering effect is obtained by means of a specially developed gas-fired burner 3. By using heat-resistant mesh material 4, wrapped around a burner bed 5, the red glow is obtained.

The gas-fired burner consists of a number of specially designed round or square structures 6 made of heat-resistant material. These structures represent a solid, such as wood.

A gas / air mixture is introduced into these structures via a gas supply 7 and an air supply 8 which is ignited by an ignition pin 9. This causes fire in these structures, the structures heat up and the heat-resistant material starts to glow.

The fire in the burners is controlled, for example, by a thermocouple 10. The thermocouple is used as safety. Only when it is heated can the gas mixture continue to flow.

If insufficient heat is generated in the heat-resistant structures, the gas supply will be cut off.

The glowing material emits a red glow which can be observed up to a distance of at least 3 meters.

These burners provide a realistic smoldering effect, not only because of the red glow, but also because of the heat emitted by the 5 burners. When in practice a solid substance still swamps, this is primarily due to the heat still present.

Another advantage of this arrangement is the fact that the structures are made of metal, just like the environment in which these burners are placed. By warming up the metal, extra steaming will occur during extinguishing.

By applying thin heat-resistant mesh material, this burner will glow quickly and achieve the desired effect, namely a red glow. On the other hand, the red glow when extinguishing rapidly decreases due to cooling of the mesh material, so that a clearly recognizable image of a well-extinguished smoldering fire is created.

The entire burner will operate independently with specially developed control 11. This control also controls a fire detection system 12, of which various parameters can be programmed. As a result, the degree of difficulty of extinguishing can be set, and a follow-up reaction can be started to another firebox 13 with real flames 14. This can also be an external firebox. The burner can also be combined with other types of fireplaces to provide a realistic exercise.

The aim of this smoldering effect to be achieved is to enable trainees to recognize a solid fire that has not yet been extinguished properly or is about to be re-ignited by the temperature present.

It will be clear that the scope of the invention is not limited to the examples discussed above, but that various variations and modifications thereof are possible without departing from the scope of the invention as defined in the appended claims.
