DEFINITION

Classification: 60/749

Having bluff flame stabilization means:

(under subclass 734) Device having means positioned to stabilize the flame as it flows in a combustion zone by creating therein a zone of decreased linear flow velocity, said means being (a) aerodynamically designed to cause the formation of eddies, vortices, etc., or (b) aerodynamically smooth with means for selective modification thereof to create a stabilization zone as by the use of fluid injected into the surrounding flow to create flow separation.
