Abstract: A feed injector for providing feed to a gasifier of an integrated gasification combined cycle system includes: a base leading to a body and terminating in a tip, the tip including an exitway for injecting feed into the gasifier; the tip including a mating of an inner shell disposed within a core insert, with an outer shell in which the core insert is disposed; a plurality of spacers disposed between the core insert and inner shell thus providing an inner annular space, and another plurality of spacers disposed between the core insert and outer shell thus providing an outer annular space; the inner annular space and the outer annular space being in fluid communication at the tip and providing for a flow of coolant from the base to the tip and back to the base. A method of fabrication and an integrated gasification combined cycle power plant are also disclosed.

Abstract: A fuel injector is provided. The fuel injector includes a nozzle, a cooling assembly, and a tip coupled to the nozzle. The tip includes a base including a cooling channel defined therein, a first transition member extending outwardly from the base and in flow communication with the cooling channel, and a second transition member extending outwardly from the base and in flow communication with the cooling channel, wherein the base, the first transition member, and the second transition member are formed integrally together. The tip is configured to couple to the cooling assembly to channel a flow of cooling fluid through the cooling channel via the first transition member and the second transition member.

Abstract: Methods and systems for a feed injector are provided. The feed injector includes a conduit including a flow passage extending along a longitudinal axis of the conduit to a distal end opening and a cooling passage integral to the conduit circumscribing the distal end opening. The cooling passage is configured to channel a flow of coolant circumferentially about the distal end opening wherein the cooling passage comprising a plurality of axially-spaced flow chambers.

Abstract: A quench ring rim and methods of fabrication are described. In one aspect, a method for fabricating a rim for use in a gasification system includes providing a hollow pipe, forming the pipe into a circular pipe, wherein a first end of the pipe is coupled to an opposite second end of the pipe, and cutting the pipe to form a rim having a desired circumference.

Abstract: An x-ray detector is provided for use in imaging systems. The x-ray detector includes a detector subsystem configured to output electrical signals in response to reception of x-rays. The x-ray detector also includes a single-piece protective enclosure having at least one opening to receive the detector subsystem.

Abstract: In one embodiment, a portable imaging device is provided with an enclosure, an imaging panel disposed in the enclosure, and shock absorbent material holding the imaging panel within the enclosure without a rigid connection between the imaging panel and the enclosure. In another embodiment, a portable imaging device is provided with a housing, an x-ray detector panel disposed in the housing, and shock absorbent material disposed between, and in contact with, both the housing and the x-ray detector panel, wherein the x-ray detector panel is generally free floating within the housing via the shock absorbent material.

Abstract: An x-ray detector is provided for use in imaging systems. The x-ray detector includes a detector subsystem configured to output electrical signals in response to reception of x-rays. The x-ray detector also includes a single-piece protective enclosure having at least one opening to receive the detector subsystem.

Abstract: Nozzles having variable geometry are disclosed that are comprised of a plurality of vanes that contact one another and can slide with respect to one another. A control element forces the vanes to slide, with contacting sides of the vanes defining an inner flow path through which a fluid may pass. The vanes may be self-similar or different from one another to define the desired geometries of the opening in the nozzles. The vanes may be configured to provide convergent, divergent and convergent-divergent nozzles for a range of applications.
