Patent ID: 8308829

Claim:
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.
