Abstract
A flame detection system is disclosed. The system may have a flame chamber and a filter, wherein the filter includes filter media configured to collect matter from an engine exhaust. Additionally, the filter may be disposed downstream of the flame chamber. An ignition device may be disposed in the flame chamber and may be configured to ignite a flame in the flame chamber to regenerate the filter. A sensor may be disposed proximate the ignition device, and may be configured to sense a change in electrical conductivity that is indicative of a presence of the flame in the flame chamber.
