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.
