Abstract: A method is disclosed for evaluating inerting concentration of a fire suppression agent. The method includes flowing air upward into a chimney tube and flowing fuel into the flowing air in the chimney tube. A targeted concentration of the fire suppression agent is introduced into the flowing air and into the flowing fuel in the chimney tube. An ignitor is ignited to provide ignition energy to the flowing air and the flowing fuel, and the ignitor is deactivated. The targeted concentration of the fire suppression agent is at or above the inerting concentration of the fire suppression agent if combustion of the flowing fuel does not persist beyond three seconds after the ignitor is deactivated.

Abstract: According to an aspect of the present disclosure, an aerosol concentration sensor calibration device includes a mixing column, a sensor, and a collection vessel. The mixing column extends in a vertical orientation between an inlet at a bottom of the mixing column and an outlet at a top of the mixing column, the mixing column configured to receive a mixture of a powder and a compressed gas at the inlet. The sensor is disposed in the mixing column and configured to measure the concentration of the powder in the mixing column. The collection vessel has an inlet fluidly coupled to the outlet of the mixing column. The collection vessel is configured to collect the powder received from the mixing column.
