A pump for transporting particulate material includes an inlet, an outlet, a passageway, a first and second load beam, a first and second scraper seal, and a first and second drive assembly. The inlet introduces the particulate material into the passageway and the outlet expels the particulate material from the passageway. The passageway is defined by a first belt assembly and a second belt assembly that are opposed to each other. The first and second load beams are positioned within the first belt assembly and the second belt assembly, respectively. The first scraper seal and a second scraper seal are positioned proximate the passageway and the outlet. The first drive assembly is positioned within an interior section of the first belt assembly and drives the first belt assembly and the second drive assembly is positioned within an interior section of the second belt assembly and drives the second belt assembly.

A slag agglomerator includes an inlet, an outlet and a plurality of obstacles. The inlet receives a flow of gas and slag droplets and the outlet allows the flow of gas and slag droplets to exit the agglomerator. The obstacles are oblique or perpendicular to the flow of gas and slag droplets and have an exterior surface containing a ceramic matrix composite.

A method of assembling a gasification reactor includes extending an injection device at least partially into the gasification reactor. The injection device includes a plurality of substantially concentric conduits coupled to a modular tip and at least one outer surface. The modular tip includes a plurality of cooling channels and a plurality of substantially annular nozzles defined therein. The method further includes forming at least one layer of insulation about at least a portion of the at least one outer surface to facilitate insulating at least a portion of the injection device from heat within the gasification reactor.

A counter-flow system for use in a turbine for selecting various mixtures of fluids for use with the system. The system may be used for a combustor for a gas powered turbine which employs a heat exchanger to combust a fuel without the emission of undesired chemical species. A gas powered turbine requires expanding gases to power the turbine blades. Fuel is combusted to produce the required gases. An oxidizer is introduced into the counter-flow system in a first direction before a first portion of fuel is introduced into the oxidizer. The fuel and oxidizer mixture is then flowed through a second pathway wherein the fuel and oxidizer mixture obtains a selected amount of thermal energy. Moreover, in a second pathway an equivalence ratio of the fuel and oxidizer mixture may be altered from the original fuel and oxidizer mixture.

A hydrogen generation system includes a hydrogen generator reacting a steam/methane mixture. Calcium oxide particles in the hydrogen generator absorb a substantial reacted portion of carbon dioxide from the reacted steam/methane mixture. The hydrogen generator discharges a hydrogen/COx gas volume. A methanation unit subsequently converts substantially all of the COx portion of the hydrogen/COx gas volume to methane gas.
摘要:
A coolant liner for a carbonaceous fuel (coal or petcoke) gasification vessel including a ceramic composite panel and a method of cooling a vessel. The panel includes at least two layers of woven yarns of fibrous material and walls extending between the layers. Accordingly, the layers and the walls define coolant channels that extend in a warp direction. Moreover, one of the layers may be less than about 0.08 inches thick. Materials used to create the composite panel may include alumina, chromia, silicon carbide, and carbon. Additionally, the liners may be shaped in an arc or have coolant channels which vary in diameter in the warp direction. Additionally, the liner may abut a structural closeout of the vessel. The coolant liner provides a significantly more durable component than previously employed liners and is especially well suited to demanding service environments.

A pump system includes a pump that includes a first belt and a second belt that are spaced apart from each other to provide generally straight sides of a passage there between. There is an inlet at one end of the passage and an outlet at an opposite end of the passage, with a passage length that extends between the inlet and the outlet. The passage defines a gap distance in a width direction between the straight sides at the passage inlet. A hopper includes an interior space that terminates at a mouth at the passage inlet. At least one screw is located within the interior space of the hopper and includes a screw diameter in the width direction that is less than or equal to the gap distance.
