GASIFIER INJECTOR

摘要

A gasifier injection module includes a two-stage slung splitter and an injector face plate with a coolant system incorporated therein. The two-stage slurry splitter includes a main cavity into which a main slurry fl ow is provided. The main cavity includes a plurality of first stage flow dividers that divide the main slurry flow into a plurality of secondary slurry flows that flow into a plurality of secondary cavities that extend from the main cavity. Eac h secondary cavity includes a plurality of second stage flow dividers that divide each secondary slurry flow into a plurality of tertiary slurry flows that fl ow into a plurality of slung injection tubes extending from the secondary cavities. The tertiary flows are infected as high pressure slurry streams into the gasification chamber via the slurry injection tubes. 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 incorporated into the injector face plate. The coolant system incorporated within the injector face plate maintains the injector face plate at a temperature sufficient to substantial ly reduce or prevent damage to the injector face plate by high temperatures and/or abrasive matter created by the resulting gasification reaction.
