Flame trap electrically heated for regeneration

A flame trap (10) for use in the exhaust system of a device in which combustion occurs, such as a diesel engine, consists of metal sheets (16, 18) forming a honeycomb-like structure with many parallel flow channels (20) through it. The flow channels (20) are less than 5mm wide. The sheets (16, 18) a...

Zusammenfassung:	A flame trap (10) for use in the exhaust system of a device in which combustion occurs, such as a diesel engine, consists of metal sheets (16, 18) forming a honeycomb-like structure with many parallel flow channels (20) through it. The flow channels (20) are less than 5mm wide. The sheets (16, 18) are connected to electrode terminals (24) so they can be heated electrically to about 600 DEG C at intervals, so as to burn off any carbon particulates which settle on them. The metal sheets are corrosion resistant at temperatures of up to 600 DEG C. Two flame traps may be used in an exhaust system. The two flame traps may be connected in parallel and valves (36, 38, figure 3) may be provided to isolate the flame traps from the outlet during regeneration.
