Oxygen-fuel burner with cavity-actuated mixing

An oxy-gaseous fuel burner (400, 500) or a solid fuel burner (700) having an annular cavity (404, 504, 704) upstream from and proximate to an outlet plane (416, 516, 716) and a converging (434, 734) or converging-diverging nozzle (537) located upstream from and proximal to the cavity (404, 504, 704)...

Beschreibung
Zusammenfassung:	An oxy-gaseous fuel burner (400, 500) or a solid fuel burner (700) having an annular cavity (404, 504, 704) upstream from and proximate to an outlet plane (416, 516, 716) and a converging (434, 734) or converging-diverging nozzle (537) located upstream from and proximal to the cavity (404, 504, 704). The solid fuel burner (700) also is preferably operated so that the velocity of gas exiting a second annulus (730) is less than the velocity of gas exiting a central conduit (710). 种氧-气态燃料喷燃器(400,500)或固体燃料喷燃器(700)，具有在出口平面(416,516,716)上游和附近的环形腔(404,504,704)，以及位于腔(404,504,704)上游和附近的会聚喷嘴(434,734)或会聚-发散喷嘴(537)。固体燃料喷燃器(700)还优选操作成使得离开第二环带(730)的气体的速度小于离开中心导管(710)的气体的速度。
