US Patent:

59414596, Aug 24, 1999

Filed:

Jul 1, 1997

Appl. No.:

8/886189

Inventors:

Donald Duane Brooker - Hopewell Junction NY
Michael Edward Fahrion - Houston TX
Gary Thomas Delgrego - Houston TX
Augustine Camacho - Bethlehem PA

Assignee:

Texaco Inc - White Plains NY

International Classification:

C10J 350
B05B 1500

US Classification:

2393975

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.
