ABSTRACT:
The uprating of existing jet engines increases the operating temperatures within the engines and also increases the tendency for flashback in some afterburner type engines. Afterburner type engines include a pilot fuel delivery pipe which is included between inner and outer annular members of a flameholder. Downstream from the pilot, partitions direct an ignited fuel/air mixture into the afterburner chamber. The afterburner flame is downstream from the flameholder, but under conditions of increased temperature the afterburner flame will tend to migrate upstream toward the flameholder. To avoid this tendency, the flameholder includes means for discharging gas which cools the flameholder metal itself while also decreasing the downstream air temperature, thereby decreasing the potential for flashback. In one embodiment, fuel and oxygen depleted turbine discharge gas are used to further decrease the tendency toward flashback.
