20130081925 | SYSTEM AND METHOD FOR TRANSPORTING SOLID FEED IN A SOLID FEED PUMP - A system includes a solid feed pump configured to transport a solid feedstock. The solid feed pump includes at least one passage for the transport of the solid feedstock. The solid feed pump also includes at least one movable wall configured to move along the passage. The solid feed pump further includes a retractable gripping element configured to extend from the at least one movable wall into the at least one passage to grip a portion of the solid feedstock. In addition, the retractable gripping element is configured to retract away from the at least one passage. | 04-04-2013 |
20130180175 | GASIFICATION SYSTEM AND METHOD FOR GASIFYING A FUEL - A system includes a gasification feed injector. The gasification feed injector includes a first injector portion configured to inject a first fuel at a first flow rate and a second injector portion configured to inject a second fuel at a second flow rate. The system also includes a fuel circulation system configured to circulate at least one fuel and supply the at least one fuel to the gasification feed injector and a controller configured to transition the gasification feed injector from injecting the first fuel to injecting the second fuel based at least on a pressure downstream of the gasification feed injector. | 07-18-2013 |
20130192137 | SYSTEM AND METHOD FOR HEATING A GASIFIER - A system includes a gasifier injector configured to inject a heat control fuel and a mixed air into a gasifier for combustion during a heat control mode. The heat control fuel is the same or different from the gasification fuel, and the system is configured to create the mixed air from independent supplies of oxygen and nitrogen. | 08-01-2013 |
20130192139 | SYSTEM AND METHOD FOR HEATING A GASIFIER - A system includes a gasifier configured to gasify a gasification fuel during a gasification mode. The system also includes a first injector configured to inject a heat control fuel and an oxygen enriched air into the gasifier for combustion during a heat control mode. The heat control fuel is the same or different from the gasification fuel, and the oxygen enriched air includes air enriched with additional oxygen. | 08-01-2013 |
20140150288 | SYSTEM AND METHOD FOR REMOVAL OF LIQUID FROM A SOLIDS FLOW - A system includes a multi-feeder assembly. The multi-feeder assembly includes a first solids feeder, a liquid removal section, and a second solids feeder. The first solids feeder is configured to receive a solids flow from an upstream system. The liquid removal section is configured to reduce an amount of liquid in the solids flow. The second solids feeder is configured to receive the solids flow in series with the first solids feeder and output the solids flow to a downstream system. | 06-05-2014 |
20140150873 | MULTI-STAGE SOLIDS FEEDER SYSTEM AND METHOD - A system includes a multi-stage solids feeder. The multi-stage solids feeder includes a first solids feeder having a first inlet and a first outlet, a second solids feeder having a second inlet and a second outlet, and a conduit disposed between the first outlet and the second inlet. The second solids feeder is disposed adjacent to the first solids feeder, and the conduit routes a solids flow from the first solids feeder to the second solids feeder. | 06-05-2014 |
20140151191 | SYSTEM AND METHOD TO SUPPLY A SOLID FEEDSTOCK TO A SOLIDS FEEDER - In a first embodiment, a system includes a first solids feeder having a first inlet and a first outlet, a second solids feeder having a second inlet and a second outlet, and an adjustable volume coupled to the first outlet and the second inlet. The first solids feeder is configured to supply a feedstock at a first feed rate and the second solids feeder is configured to supply the feedstock at a second feed rate. The adjustable volume is configured to adjust based at least in part on first feed rate and the second feed rate. | 06-05-2014 |
20150159098 | SYSTEM AND METHOD FOR COOLING SYNGAS WITHIN A GASIFIER SYSTEM - A vessel for use in a gasification system is provided. The vessel includes a shell and a heat exchange structure positioned within the shell. The heat exchange structure defines a central cavity configured to receive and to direct a syngas to a quenching portion positioned downstream of the central cavity along a syngas path. A passageway is disposed between the shell and the heat exchange structure. A liquid seal is positioned upstream of the quenching portion, and the liquid seal is configured to block transport of at least one of the syngas between from the quenching portion into the passageway and inert gas from the passageway into the quenching portion. | 06-11-2015 |
