Abstract: The fuel injector nozzle (10) for a gasifier includes a protective recfracto ry sheath (70) that is flush mounted at a downstream end proximate the nozzle outlet portion (40). The refractory insert (72) is of annular form to surrou nd the nozzle outlet. The annular refractory member can be a one-piece structur e or a multi-segment structure. Whether the annular refractory member is a one - piece structure or a multi-segment structure, it is recessed in a downstream end surface of the fuel injector nozzle and retained in the recess by locati ng pins (110) or by thread-like engagement between a projection (144) and a groove (172) that are provided on complementary inter-engaging surfaces of t he recess and refractory member. The enduring presence of the annular refractor y member prolongs the service life of the fuel injector by protecting the vulnerable surface areas at the downstream end of the fuel injector nozzle that are close to a hot and corrosive reaction zone within the gasifier.

Abstract: The fuel injector nozzle for a gasifier includes a protective refractory sheath that is flush mounted at a downstream end proximate the nozzle outlet portion. The refractory insert is of annular form to surround the nozzle outlet. The annular refractory member can be a one-piece structure or a multi-segment structure of preferably not more than four pieces. Whether the annular refractory member is a one-piece structure or a multi-segment structure, it is recessed in a downstream end surface of the fuel injector nozzle and retained in the recess by locking pins or by thread-like engagement between a projection and a groove that are provided on complementary inter-engaging surfaces of the recess and the refractory member. The retaining structure provided on the annular refractory member and at the recess in which the refractory member is disposed securely maintain the annular refractory protective member in position. The enduring presence of the annular refractory member prolongs the service life of the fuel injector nozzle by protecting the vulnerable surface areas at the downstream end of the fuel injector nozzle that are close to a hot and corrosive reaction zone within the gasifier.
