Process and device for controlling the regeneration of an element filtering oxidable particles carried along by a gaseous stream, by periodic combustion of these particles, such as, for example, the carbon-containing particles carried along in the exhaust gas of a thermal engine (3), retained in an exhaust silencer (1). In an application to a thermal engine, the process comprises detecting the variation, measured by detectors (4, 5), in the oxygen content of the gaseous stream between at least a first point located upstream, in relation to the direction of flow, from filtering element (1) receiving the stream and at least a second point located downstream from the first one, resulting from a reaction of combustion of the particles accumulated in the filtering element, initiated by a management element (6) acting for example on the running of engine (3), which allows the latter to adjust with precision the stage of regeneration of the filtering element and therefore to limit overconsumption as far as possible.

The machine as recited in claim 6, further comprising a non-flammable dryer hose connection to said dryer. 8. The machine as recited in claim 6, wherein said fire extinguisher means is a carbon dioxide extinguisher. 9. The fire arrester kit as recited in claim 6, wherein said delaying means includes a pressure sensor adapted to sense pressure in said flow path of said dryer, said delaying means de-energizing said blower when said pressure in said flow path reaches a pre-selected level. 10. The fire arrester kit as recited in claim 6, wherein said fire detector is a smoke detector. 11. A machine, comprising: a clothes dryer having a flow path from an inlet to an outlet, and an interior volume, said dryer having a blower that forces air from said inlet to said outlet,and a heat source; a fire detector positioned at said outlet of said clothes dryer, said fire detector being adapted to detect a fire and to emit a signal when said fire is detected; means for extinguishing a fire, said extinguishing means being positioned at said inlet of said clothes dryer and responsive to said signal from said fire detector, said fire extinguishing means being adapted to extinguish a fire in said flow path of said dryer; dryer de-energizing means for de-energizing said heat source and said blower of said dryer, said dryer de-energizing means being responsive to said signal from said fire detector; and a filter means positioned near said inlet of said flowpath adapted to filter airborne material from said flowpath. 12. The machine as recited in claim 11, wherein said filter is adapted to be removable for cleaning.
