Abstract: A system includes a radiant syngas cooler which receives and cools syngas generated in a gasifier. The radiant syngas cooler includes an outer shell of the radiant syngas cooler defining an annular space of the radiant syngas cooler and a heat exchange tube of the radiant syngas cooler positioned within the annular space and configured to flow a cooling medium. The heat exchange tube is configured to enable heat exchange between the syngas and the cooling medium to cool the syngas. The radiant syngas cooler includes a downcomer tube of the radiant syngas cooler which supplies the cooling medium to the heat exchange tube, where the downcomer tube includes a downflow portion positioned outside of the annular space of the radiant syngas cooler. The downflow portion is fluidly coupled to a header, and the header fluidly couples the downcomer tube to the heat exchange tube.

Abstract: A system for preheating a pressure vessel includes a throat including an area of excess heat and a dome having an area of deficient heat. The throat includes a conduit extending from a pressure vessel opening to the pressure vessel interior. A plenum is defined between the throat and a seal within the dome. The throat extends from the dome toward a dome floor. The floor is substantially perpendicular to the throat. A conduit is coupled to the plenum and channels a flow of purge fluid into the plenum wherein heat from the throat is transferred to the flow of purge fluid and carried by the flow of purge fluid into the area of deficient heat via a gap defined between the seal and the floor such that the flow of purge fluid reduces temperature differential stresses within the pressure vessel and purges the area of deficient heat.

Abstract: A syngas cooler is configured to cool a syngas. The syngas cooler includes a superheater heat exchanger, which further includes a first header configured to receive saturated steam, a second header configured to discharge superheated steam, and a first group of tubes directly coupled to and vertically extending between the first and second headers. Each tube of the first group of tubes includes an outer surface that interfaces with the syngas and a respective length between the first and second headers, and each tube of the first group of tubes does not contact another tube along the respective length to enable a flow of the syngas around each tube's outer surface along its respective length and between each tube.

Abstract: 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.

Abstract: A syngas cooler system includes a pressure vessel, a conduit, a plenum, a plenum, a conduit, and a bellows assembly. The pressure vessel includes a throat and a dome adjacent to the throat. The throat includes an area of excess heat, and the dome includes an area of deficient heat. The plenum extends between the throat and the bellows assembly. The bellows assembly is coupled at least partially within the dome. The conduit is coupled to the plenum for channeling a flow of purge fluid from external to the pressure vessel into the plenum such that purge fluid transfers heat from the area of excess heat into the area of deficient heat to facilitate reducing temperature differential stresses within the dome and the pressure vessel.
