Gasifier injector

A method for gasifying a carbonaceous material, said method comprising:

• supplying a main slurry flow to a main cavity of a two-stage slurry splitter of an injection module;
• dividing the main slurry flow into a plurality of secondary slurry flows that flow into a plurality of secondary cavities extending from the main cavity at distal ends of a plurality of first stage flow dividers;
• dividing each secondary slurry flow into a plurality of tertiary slurry flows that flow into a plurality of slurry injection tubes extending from each secondary cavity at distal ends or a plurality of second stage flow dividers;
• injecting the tertiary slurry flows into a gasification chamber coupled to the injector module, via the slurry injection tubes;
• impinging each of a plurality of annular shaped sprays of a reactant onto a corresponding one of the tertiary slurry flows within the gasification chamber, via a plurality of annular impinging orifices incorporated in a face plate of the injector module, wherein each impinging orifice surrounds a corresponding slurry injection tube;
• and
• cooling the face plate so that the face plate will withstand high temperatures and abrasion caused by a gasification reactant generated by impinging the reactant onto the tertiary slurry flows.
