Heat shield for feed injector

摘要

A system includes a gasification feed injector. The gasification feed injector includes a tip portion that has an outer wall and a feed outlet, and an injection axis of the gasification feed injector extends through the feed outlet of the tip portion. The gasification feed injector also has at least one fastener extending radially from the outer wall relative to an injection axis of the gasification feed injector through the feed outlet of the tip portion. An attachment location of the at least one fastener is located away from the feed outlet of the tip portion. The system also includes a heat shield, which includes a tile radially disposed on the at least one fastener and radially secured to the outer wall via fastening the tile to the at least one fastener. In addition, the tile wraps around a distal end portion of the tip portion.

1. A system comprising:
a gasification feed injector, comprising:
a tip portion comprising an outer wall and a feed outlet, wherein an injection axis of the gasification feed injector extends through the feed outlet of the tip portion; andat least one fastener extending radially from the outer wall relative to the injection axis wherein an attachment location of the at least one fastener is located away from the feed outlet of the tip portion; and a heat shield, comprising:
a tile radially disposed on the at least one fastener and radially secured to the outer wall via fastening the tile to the at least one fastener, wherein the tile wraps around a distal end portion of the tip portion; andan insulation layer disposed between the outer wall and the tile, wherein the insulation layer has a first surface and a second surface disposed opposite the first surface, and the first surface directly contacts the outer wall and the second surface directly contacts the tile, and wherein the at least one fastener extends through a portion of the tile having the insulation layer disposed radially inward of the portion of the tile.
