  • As mentioned, the temperature can be controlled from ambient to 1000°C, with an accuracy of ±2°C. The temperature ramp rate can be adjusted from 1°C per minute to 80°C per minute, allowing for the simulation of both slow and rapid temperature changes. For example, a slow ramp rate can be used to study the thermal degradation of a material over time, while a rapid ramp rate can mimic the sudden heat increase during a fire outbreak.
• Flame Intensity and Control Parameters
  • The flame intensity can be adjusted over a wide range, with a maximum heat output equivalent to several megawatts per square meter. The fuel flow rate can be varied from a few milliliters per minute to several liters per minute, and the air-fuel ratio can be precisely controlled within a range of 1:1 to 14:1. These parameters enable the creation of flames with different characteristics, from a small, stable flame for precision testing to a large, turbulent flame for more severe fire simulations.
• Data Acquisition Rate and Resolution
  • The data acquisition system samples sensor data at a rate of 9000 samples per second. The temperature sensor has a resolution of 0.1°C, the smoke density sensor can detect changes as small as 0.01% opacity, and the gas sensors have a sensitivity in the parts per million (ppm) range for most common gases.
