Gasifier injector

摘要

A gasifier injection module (10) includes a two-stage slurry splitter (22) and an injector face plate (30) with a coolant system incorporated therein. The two-stage slurry splitter (22) includes a main cavity (38) into which a main slurry flow is provided. The main cavity (38) includes a plurality of first stage flow dividers (42) that divide the main slurry flow into a plurality of secondary slurry flows that flow into a plurality of secondary cavities (46) that extend from the main cavity (38). Each secondary cavity (46) includes a plurality of second stage flow dividers (50) that divide each secondary slurry flow into a plurality of tertiary slurry flows that flow into a plurality of slurry injection tubes (26) extending from the secondary cavities (46). The tertiary flows are injected as high pressure slurry streams into the gasification chamber (18) via the slurry injection tubes (26). A reactant is impinged at high pressure, as an annular shaped spray, on each high pressure slurry stream via a plurality of annular impinging orifices (34) incorporated into the injector face plate (30). The coolant system incorporated within the injector face plate (30) maintains the injector face plate (30) at a temperature sufficient to substantially reduce or prevent damage to the injector face plate (30) by high temperatures and/or abrasive matter created by the resulting gasification reaction.
