Abstract: 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.

Abstract: A system includes a gasifier, which includes a reaction chamber configured to convert a feedstock into a synthetic gas, a quench chamber configured to cool the synthetic gas, a quench ring configured to provide a water flow to the quench chamber, and a quench ring protection system configured to protect the quench ring from the synthetic gas or a molten slag. The quench ring protection system includes a protective barrier disposed within an inner circumferential surface of the quench ring. The protective barrier substantially overlaps the inner circumferential surface in an axial direction along an axis of the quench ring.

Abstract: A system, in certain embodiments, includes a gasification cooling system having an annular seal with a bellows. For example, the gasification cooling system may include a housing with an inlet, an outlet, and an interior between the inlet and the outlet, wherein the interior has a throat adjacent the inlet, and the throat expands in a flow direction from the inlet toward the outlet. The annular seal may be disposed in the throat of the housing, wherein the annular seal includes the bellows.

Abstract: A vessel comprises a probe oriented downward from an outside surface of the vessel to an inside surface of the vessel. A method of operating a vessel, the vessel comprising a vessel wall having an inside surface and an outside surface, comprises: defining a hole extending through the vessel wall, the hole being oriented at a downward angle from the outside surface to the inside surface; and placing a probe in the hole; and preventing slag buildup around the probe during operation of the vessel.

Abstract: A refractory wall is provided. The refractory wall includes a plurality of wall bricks coupled together to define an inner surface of the refractory wall, and a sensor port coupled to the plurality of wall bricks. The sensor port includes an outer wall defining a radial cross-sectional shape of the sensor port and defining a top ridge of the sensor port, an inner wall defining an opening extending through the sensor port, and an end wall extending between the outer wall and the inner wall. The end wall is positioned radially inward a distance from the inner surface. A method for fabricating the refractory wall is also provided.
