Abstract:
1. A gas feed injector apparatus, comprising: a mounting flange having an internal surface, and configured to be coupled to a gasifier housing with a reaction zone for supporting a syngas reaction in a temperature range of up to about 2279° F.; a first internal gas inlet pipe coupled to the mounting flange; a second internal gas inlet pipe coupled to the mounting flange; a cooling coil inlet coupled to the mounting flange; cooling coils coupled to the cooling coil inlet, and configured to be positioned internally in a gasifier housing; and an internal gas injection header coupled to the first and second internal gas inlet pipes, and configured to inject a first gas, the internal gas injection header positioned outside the reaction zone and subject to temperatures of about 1192° F., wherein the mounting flange is configured to receive a gas injector barrel in a position adjacent the internal gas injection header and the cooling coils, and configured to inject fuel to mix with the first gas, and wherein the cooling coils are positioned around the gas injector barrel.
