A screw feeder can be used to transport a high temperature particulate material. A housing contains the material within the screw feeder which includes an inlet and an outlet port. A screw is rotatably positioned within the housing to advance the material from the inlet port to the outlet port, which rotates axially. A labyrinth seal can be formed around and in communication with the screw to eliminate reverse movement of the material. A cooling medium can be directed into contact with at least the housing. A fluid can be injected through the screw to prevent blockage of the particulate material. A pressure differential is created from the inlet to the outlet port of at least 0.069 MPad.

A cyclone separator includes a body having a side entry fluid inlet, a first outlet and a second outlet both aligned substantially transverse to the fluid inlet, and has the first and second outlets opposing each other. A cyclone tube assembly is positioned within the body having at least a portion of the cyclone tube assembly positioned in a direct unobstructed alignment path with the fluid inlet. The cyclone tube assembly includes a plurality of cyclone tubes, each including a first tube section and a second tube section partially positioned within the first tube section. A ceramic material forms at least a portion of the second tube section of each cyclone tube. A first tube connection plate supports the first tube section of each of the cyclone tubes. A second tube connection plate supports the second tube section of each of the cyclone tubes. The first tube connection plate is angularly offset from the second tube connection plate.
摘要:
A combustor and injector system to inject a selected fuel into a combustor of a gas powered turbine. Generally, the injector is able to inject a selected fuel into a stream of an oxidizer to substantially mix the fuel with the oxidizer stream before any of the fuel in the fuel fan reaches an auto ignition temperature. Therefore the fuel may be substantially combusted at once and without any substantial hot spots.

A gasifier injection module includes a two-stage slurry splitter and an injector face plate with a coolant system incorporated therein. The two-stage slurry splitter includes a main cavity into which a main slurry flow is provided. The main cavity includes a plurality of first stage flow dividers that divide the main slurry flow into a plurality of secondary slurry flows that flow into a plurality of secondary cavities that extend from the main cavity. Each secondary cavity includes a plurality of second stage flow dividers that divide each secondary slurry flow into a plurality of tertiary slurry flows that flow into a plurality of slurry injection tubes extending from the secondary cavities. The tertiary flows are injected as high pressure slurry streams into the gasification chamber via the slurry injection tubes. A reactant is impinged at high pressure, as an annular shaped spray, on each high pressure slurry stream via a plurality of annular impinging orifices incorporated into the injector face plate. The coolant system incorporated within the injector face plate maintains the injector face plate at a temperature sufficient to substantially reduce or prevent damage to the injector face plate by high temperatures and/or abrasive matter created by the resulting gasification reaction.
摘要:
A system for providing highly pressurized raw fuel to a pressure reactor. The system includes an inlet for receiving the raw fuel and a roller system communicating with the inlet. The roller system includes a plurality of independent rollers arranged in two converging planes. The rollers of the roller system successively compress the raw fuel as the raw fuel passes through the roller system between the rollers, such that the fuel is highly pressurized when it reaches an output end of the roller system. An outlet is located adjacent the output end of the roller system to dispense the pressurized raw fuel to the pressure reactor.

A gasifier system is provided that includes a gasification chamber spool that has a ceramic matrix composite (CMC) liner adapted to form a solidified slag protective layer on an interior surface of the liner from molten slag flowing through the gasification chamber spool. The gasification system additionally includes a heat exchanger (HEX) quench spool that also includes a CMC liner adapted to form a solidified slag protective layer on an interior surface of the liner from molten slag flowing through the HEX quench spool. Additionally, the HEX quench spool includes a parallel plate HEX core having a plurality of CMC panels. The CMC panels are adapted to form a solidified slag protective layer on exterior surfaces of each respective CMC panel from molten slag flowing through the HEX quench spool. Furthermore, each CMC panel includes a plurality of internal coolant channels adapted to exchange sensible waste heat from the hot product flowing through the HEX quench spool with a coolant flowing through the internal coolant channels. The sensible waste heat absorbed by the coolant is recovered by the gasification system by utilizing the heated coolant in various operational phases of the gasification system.
摘要:
A combustor for a gas powered turbine which employs a heat exchanger and a catalyst 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. A catalyst is employed to lower the combustion temperature of the fuel. The catalyst is placed on a set of tubes in the heat exchanger such that a portion of the thermal energy may be transferred to the air before it engages the catalyst. After encountering the catalyst, the combusted fuel increases the temperature of the air to an auto-ignition temperature so that no other ignition source is needed to combust additional fuel.

A system, such as a turbine power production system, including a plurality of combustion chambers. The combustion chamber may be provided with an ignition system that allows for substantially simultaneous ignition of each of the plurality of the combustors. Generally, a detonation wave may be provided to each of the combustion chambers substantially simultaneously from a single ignition combustion wave chamber.
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.
