Modular Burn Chamber for Flame Testing
- Self-contained, enclosed space built from metal-lined, flame retardant materials
- Suitable for installation within a laboratory space or outdoors by adding protection from direct weathering
- Supplied with pre-engineered ventilation system to supply oxygen for combustion, and to vent the heated chamber space after a burn.
- Built-in safety sensors and interlocks to protect operators and equipment
- Large viewing window in wall, and safety window in access door.
Fully ventilated, fire-resistant burn enclosures with viewing window and access door with window are provided to house the manikin and burner apparatus. Concept drawing of the Modular Burn chamber is shown in the figures below. The chamber will be sized to meet the F1930 standard’s minimum dimensions of 2.1 x 2.1 x2.4 meters, to provide a uniform flame exposure and sufficient space for safe movement around the manikin for dressing without accidentally jarring and displacing the burners. A properly sized forced air exhaust system permits rapid removal of combustion gas products and aid in cooling after the data acquisition period.
A system of propane gas piping, pressure regulators, valves, and pressure sensors are used to safely deliver gaseous fuel to the ignition system and exposure torches. This delivery system is sufficient to provide a uniform heat flux of at least 2.0 cal/cm2·s (84 kW/m2) for an exposure time of at least 5 seconds.
