Abstract: An engine component for a turbine engine includes a particle collector having a substrate configured to retain at least some particles from a particle-laden stream passing through a portion of the engine. A fluid bypass around the substrate of the collector enables the particle-laden stream to bypass the substrate if the substrate is filled with particles.

Abstract: A fruit cutting device includes a divider and a pusher. The divider includes a closed-shaped divider frame, blades connected with and positioned within the divider frame, and divider handles on opposing sides of the divider frame. The blades include an upper edge and a lower cutting edge. The divider is configured to be pushed in a cutting direction through a fruit to divide the fruit into sliced segments. The pusher is configured to push the sliced segments through gaps between blades in a pushing direction, which is away from the cutting edges of the blades, and is configured to connect with the divider.

Abstract: A mountable enclosure can include a base and a door pivotally connected along a vertical axis. The base and door can include electronic component mounting areas, horizontal cable management areas, and vertical cable management areas. A mounting system can include at least one enclosure and at least one bracket, the bracket having a rigid body with first, second, and third parallel surfaces wherein the first and third surfaces are on one plane and the second surface is on a different plane. The bracket can be fastened to the wall and the enclosure can be fastened to the bracket and the wall. Multiple enclosures can be installed in vertical alignment through a method that can require only one installer and the leveling of only the first bracket wherein notches in subsequent brackets are mated with pegs extending from the base of previously installed enclosures.

Abstract: Gasification cooling systems provided herein may include a housing having a fluid passage extending in a flow direction lengthwise along the housing and an annular wall disposed about the fluid passage and having one or more annular steps. Such systems may also include a plurality of heat exchanger tubes downstream of the one or more annular steps and adapted to cool a syngas in the gas passage as the syngas flows in the flow direction.

Abstract: A gasification quench chamber is disclosed. The gasification quench chamber includes a reservoir that contains liquid coolant in its lower portion and an exit for the cooled syngas in its upper portion; a dip tube that is configured to introduce a syngas mixture to contact the liquid coolant which produces the cooled syngas; a cooling device configured to further cool the cooled syngas in its upper portion; and a stability device in the lower portion that is configured to mitigate coolant level fluctuation and sloshing. In an embodiment of the quench chamber, the cooling device includes a heat exchanger pipe. A quench chamber and scrubber assembly is also disclosed.

Abstract: A gasifier includes a combustion chamber in which a fuel is burned to produce a syngas and a particulated solid residue. A quench chamber is disposed downstream of the combustion chamber. A dip tube is disposed coupling the combustion chamber to the quench chamber. The syngas is directed to contact liquid coolant in the quench chamber and produce a cooled syngas. A draft tube is disposed surrounding the dip tube such that an annular passage is formed. A baffle is disposed proximate to an exit path of the quench chamber. The cooled syngas is directed through the annular passage and impacted against the baffle so as to remove entrained liquid content from the cooled syngas before it is directed through the exit path. A cross sectional area of the annular passage is larger towards the bottom of the quench chamber and smaller towards the top of the quench chamber.

Abstract: Embodiments of gasification cooling systems provided herein may include a housing, an annular wall, and one or more tangential fluid jets circumferentially disposed about the annular wall. The housing includes an inlet, an outlet, and a fluid passage disposed between the inlet and the outlet. The annular wall is disposed about the fluid passage, and a fluid stream is configured to flow in a flow direction from the inlet toward the outlet. The one or more tangential fluid jets are adapted to inject fluid into the fluid passage to annularly circulate the fluid stream throughout the fluid passage as the fluid stream flows in the flow direction.

Abstract: A stator-rotor assembly is described, including at least one interface region and a gap between a surface of the stator and a surface of the rotor. The stator is a nozzle or vane that includes circumferential endwalls. Each endwall includes at least one leading edge and one trailing edge, relative to a hot gas flow path. A trailing edge of at least one of the endwalls includes a pattern of cavities that are capable of impeding the entry of hot gas into a wheelspace region that adjoins the gap between the stator and the rotor. The cavities can also be formed on various sections of the rotor. The stator-rotor assembly can be incorporated into various turbomachines, such as gas turbine engines. Related processes are also described.
