Inert gas fire protection system

Abstract

methods, apparatuses, and systems for harvesting inert gas exhausted from an engine and using the harvested inert gas to prevent an ignition event and/or extinguish an ignition event. The temperature of the harvested inert gas may need to be lowered. Unwanted components may be removed from the harvested inert gas. Combustion components may be completely burned from the harvested inert gas prior to providing the harvested inert gas to a fire protection system. The fire protection system uses the harvested inert gas to extinguish an ignition event and/or to provide a purge flow to prevent an ignition event. The fire protection system may be on an aircraft. Sensors may be used to detect an ignition event. Pressure sensors may be used to monitor the pressure of the harvested inert gas as well as to monitor the purge pressure of areas receiving a continuous purge flow of harvested inert gas.
