摘要： The operational life of a synthesis gas generation reactor burner nozzle is improved, at least about 14%, by a faired lip around the nozzle discharge orifice projecting about 0.95 cm from the nozzle end face. The lip is faired with a 45.degree. conical angle from the nozzle face. A smooth transition of recirculated gas flow across the nozzle face into the reactive material discharge column is believed to promote an attached static or laminar flowing boundary layer of cooled gas that insulates the nozzle face, to a degree, from the emissive heat of the combustion reaction.

摘要： A burner nozzle assembly for the production of synthesis gas in a synthesis gas generation chamber has a cooling water jacket face that is protected from hot gas corrosion by an annular shield fabricated from a high melting point material. The heat shield is affixed to the cooling water jacket face by means of a threaded retaining member that engages in one of the surfaces an aligned channel having correspondingly mating threads.

摘要： A coal gasification feed injector is disclosed having an oxidation-resistant insert which prevents oxidative corrosion of the shield, and the subsequent damage to the underlying face of the feed injector. The life of the feed injector, and thus the length of a single gasification campaign, is thereby extended.

摘要： A coal gasification nozzle is disclosed having a barrier, integral with the face of the injector, that fits into a groove of a heat shield attached to the nozzle face. The barrier prevents oxidative corrosion of the shield, and subsequent damage to the underlying face of the feed injector, by preventing diffusion of corrosive species to the threaded ring by which the heat shield is attached to the face of the nozzle. The life of the injector, and thus the length of any single gasification campaign, is thereby extended.

摘要： The water jacket face of a burner nozzle for a synthesis gas generator is protected from hot gas corrosion by an annular heat shield of high temperature melting point material. The heat shield element is secured to the water jacket face by means of six, for example, radially aligned bayonet mounts. Along each of the radial mounting lines, a pair of radially aligned posts project from the water jacket face. Blind sockets in the heat shield back side surface are aligned to receive the posts therein. Radial bayonet channels between the heat shield face side and backside surfaces connect the inner outer heat shield perimeters through the posts and post sockets. Bayonet wires through the bayonet channels secure the heat shield position relative to the water jacket face.

摘要： The water jacket face of a burner nozzle for a synthesis gas generator is protected from hot gas corrosion by an annular heat shield of high temperature melting point material. The shield material is formed into two ceramic rings that face or cover the nozzle water jacket face. A circular joint between the outer perimeter of an interior shield annulus is stepped to provide a protective lap with the interior perimeter of an exterior shield annulus. The interior ceramic ring is secured in place around the burner nozzle orifice by external lugs projecting radially from the nozzle extruder lip. A second set of external lugs is provided around the outer perimeter of the water jacket face. Internal sectors within a perimeter cuff bracket secure the outer ceramic ring to the water jacket face.
