Abstract
A flameholder stabilization plate attaches to the lower part of a flameholding baffle disposed in an afterburner system of a turbofan engine. The plate includes extension tabs which extend laterally from a main body of the plate and block contact by cool fuel droplets entrained in a cold fan air stream flow with the baffle. The tabs disperse some large droplets into smaller ones which flow to a recirculation flame zone behind the baffle where a leaner fuel-air mixture is formed. Other large droplets of fuel are directed by the tabs to combustion zones at lateral sides of the baffle where a richer fuel-air mixture is formed. The leaner mixture in the recirculation zone will result in a more stable flame which, in turn, will more efficiently burn the richer mixture of fuel in the lateral combustion zones.
